Title: '72 Fulvia rebuild
Post by: Keithver on 24 August, 2020, 10:02:39 AM
Hi. I'm new to the forum, new to Lancias and new to rebuilding - my first rebuild project. Thanks to all of you for informing me and for the inspiration, especially Norm Thomas for his detailed 'workshop-manual-like' posts. I bought it at the beginning of March. When I got it home my wife wanted to know why I wanted to rebuild it. She said it looks fine as is.
Besides the odd little bit of rust here and there  ::) ha ha! she didn't run very well. I eventually discovered that the fuel return line inside the tank was blocked causing carb #1 to flood horribly. By the time I had sorted this I had removed the seats and so had to drive sitting on the floor boards. We live on a small holding so quiet and no traffic (also illegal I imagine) I think the engine will be okay. I'll keep you up dated

Keith,
Throw the radio away, fit a blanking panel with the lovely Fulvia script, then listen to the music of a Fulvia engine.
Good luck whichever way you decide to go.

during lockdown, I have stripped everything out of the car so that it is only the shell. While waiting (lock down) to be able to take it for sandblasting I did some investigation of my own.
I removed paint and plenty of body filler as the photos show.
I discovered a fair amount. The car had been resprayed and badly re-assembled. As I was taking it apart and found things missing or badly done, I would go to the spares pile I received with the car and look for things. I was amazed at what I found and how much I was able to re-instate in the car (which could easily have been done by the previous assembler). Once I had worked out where the pile of spares needed to go, I was able to label everything and take photos.
Rust - there was rust all over. A lot of it due to the lousy repairs, the overuse of filler and the respray. All the drain holes in the door bottoms etc. had been closed up. Nowhere for the water to go! The quality of the welds can be seen in the front inner wheel arch (last photo). The bonnet and boot lid skins and inner frames had been attacked. The sills (inner and outer), wheel arches, both floor pans, the battery tray, door lower skins (outer and inner), the petrol tank surround, the rear parcel shelf, The rear window surround, even the middle skin in the rear left C pillar and the rear valance.
She is back from the sand blasting, so all is revealed. I am working through as many of the repairs as I can myself and waiting for a slot at the repair and paint shop for now

Yes Chris. She has been stripped from top to bottom and been given a protective layer. The photo shows her as she is now

Post by: Keithver on 14 September, 2020, 03:35:46 PM
Now that the whole car is in pieces, it is time to start checking everything. I started with the drive shafts. Although it is a Series 2 car, I seem to have Series 1 drive shafts (which is apparently normal???) TAV50 in the book.
To get them apart I placed the shaft in the vice and gave the outer joint a swift tap with a dead-blow hammer. They pop off easily enough. To get the inner(gearbox) joint off, you need to remove the cir-clip on the shaft end (photo 1) and slide the inner joint off. I cleaned off the grease with a power washer as best I could. I nicked alignment marks into the 3 pieces of each joint with the grinder (photo 2) for later re-assembly.

Remove the large cir-clips from the outer sleeve of the gearbox joint. Pull the sleeve off. That releases the 24 x 9,5mm or 3/8" balls (4 per slot). Rotate the middle ring of the joint (photo 4) so that you can remove each ball (6 x 12,8mm or 1/2" per joint). Removing the inners of the joint is a matter of tilting the middle ring (photo 3) to allow one of the 2 larger holes to line up with a nib on the outer housing and jiggling it out. The center piece needs to be turned so that 1 of its nibs line up with a large hole and can be jiggled out.

My ball races seem to be in good condition so I just replaced all the balls which were a little worn. Grease everything up with black CV grease before re-assembling using your alignment marks and insert the balls. The workings of the inner and outer joints is the same process. Make sure that you replace all 4 cir-clips on the gearbox joint. I left one out so had to remove the joint and fit it in  all of that new grease. :'( ::) Not easy!

Put the boots and the alu. cover onto the shaft before fitting the joints. Squeeze the outer wire shaft cir-clips so that they are the proper size and click them into their slots on either end of the shaft. The metal sleeve on the inner end of both the splines needs to be moved up the spline to cover and compress the cir-clip (photo 5). Fill the center (female) holes of the joints with CV grease and slot the joint onto the shaft splines. A bit fiddly, but you can feel when it is correct. Give the joint a good whack with a dead-blow hammer to slide all the way down the shaft.

The new outer boots come with a metal ring instead of a clamp to fix them to the joint. Push the outer joint right into the boot as far as it will go. The steel outer casing of the joint has a lip to stop the boot and clamp from coming off, You maneuver the ring over the boot from the outside of the joint and butt it up against the boot lip (photo 6). Pull the outer joint out of the boot again and the ring will clamp the whole lot nicely in place.

Post by: nistri on 15 September, 2020, 07:46:26 AM
Nice work, well done. Before refitting the small clip to the outer boot, with great care insert a long screwdriver into the boot and move the CV joint around to allow air to escape or vacuum to be formed. This ensures that the CV boot will last more than 1 week. Andrea

I took the exhaust manifold to a specialist to have it checked out. He said that he hadn't seen such a good quality manifold for years. It is brown and surface rusted but seems as if it is in good condition otherwise. He did suggest that I have it cleaned up and ceramic coated inside a out. It seems as if the ceramic stops further corrosion and runs cooler. Has anyone got any experience with ceramic coating and is it worth the price. ZAR2800 to have it done. Probably just over GBP130


Title: Re: '72 Fulvia rebuild
Post by: Walbarr on 16 September, 2020, 05:41:35 PM
Ive seen this done several times on Wheeler Dealers
Its supposed to reduce heat in the engine bay as well helping slightly with power so I would say worth it
Id like to get my Appia exhaust manifold coated inside and out if I can somewhere that does it close by


Title: Re: '72 Fulvia rebuild
Post by: lancialulu on 16 September, 2020, 09:01:35 PM
Fwiiw fulvia exhaust can glow cherry red but are buried on the other side of the engine far away from the carbs. I have travelled all over Europe in my Fulvia sometimes in 30deg plus heat and not had any problems. Ceramic can protect mild steel exhausts from corrosion but my limited experience with this is that it only last c5 years before breaking down (outside gtee period!).


Title: Re: '72 Fulvia rebuild
Post by: Keithver on 15 October, 2020, 12:20:25 PM
The car is about to go to the bodywork/spray painter to do all of the structural work (sills etc) that I'm not comfortable handling. I am checking the fit of windows etc  before she is painted so that I don't have to do it with new bright shiny paintwork.
Am I right in presuming that the outer door edge that takes the s/s outer trim should be a straight line. (see photo)The two "U" channels that secure the vent window at the front give an opening of 16/17mm. should that continue all the way back to just behind the opening for the lock knob. Are the inner and outer lips parallel? mine were all over the place before I straightened the one in the photo


Title: Re: '72 Fulvia rebuild
Post by: nthomas1 on 16 October, 2020, 10:17:54 PM
The sides should be parallel.  The width of the front section where the quarter light fits is determined by the three cross braces where the captive  nuts are located.  I can't recall if the rest of the opening is the same width or slightly different.   You can probably judge by looking at the width of the major portion, then ease (usually) narrower areas out to match. The gap has to take the following, reading from the inside of the car outwards:  rear surface of inner door top grained trim piece; furry weatherstrip; glass; furry weatherstrip; inner portion of external stainless steel trim strip.


Title: Re: '72 Fulvia rebuild
Post by: Keithver on 17 October, 2020, 11:26:25 AM
thanks Norm. The rear flange for the vent fixing was buckled and caused a large crown (horizontally) along the outer lip. Reshaping the flange back to original has lessened the crown and it now matches the other door's slight crown. I have the inner and outer lips parallel. I only have the old trim bits and pieces at this stage (all to be replaced with new), but they seem to fit properly now. Thanks again for the help. Appreciated

I am going to have to make a final choice on the colour of the car soon and rather like the colour in the photo. Can anyone tell me definitely what the name of the colour is please


Title: Re: '72 Fulvia rebuild
Post by: Lightweight_911 on 22 October, 2020, 07:28:05 AM

That looks like 'Turchese Mereweld' - one of my favourite colours for an S1 Coupe ...

I don't think it was offered on S2 models though.

Title: Re: '72 Fulvia rebuild
Post by: lancialulu on 22 October, 2020, 07:37:51 AM
If metallic (hard to tell) then Blue Jamaica (the light version)??


Title: Re: '72 Fulvia rebuild
Post by: Keithver on 22 October, 2020, 01:36:29 PM
The website where I got the photo from said the colour is Blu Mendoza. I think this is too light for Mendoza. The other photos of the same car all show the colour as an almost cyan colour. Turchese Mereveld is a good call, but an internet search shows as many light green cars as light blue????. Paul Mayo (member of the forum) shows it as a green colour in his extensive colour chart. I cant find the cyan colour on his chart though unfortunately.
The colour in the photo above is not metallic. I think my car was originally Blu Jamaica. As in the inner darker ring in the photo. I didn't realize that there was a lighter version of the Jamaica.
I really like the cyan and would like to use it. I'm not building a concourse car. Would it matter if I used a series 1 colour on a series2 car?


Title: Re: '72 Fulvia rebuild
Post by: Lightweight_911 on 22 October, 2020, 02:43:16 PM

Looking at the S1 Coupe shot above on a different screen/device it now looks much 'bluer' so my suggestion of Turchese Mereweld was obviously incorrect ...

You are right Robert - it does look similar in some of the pics. The Turchess (turquoise in Itallian) seems a little green though. Doing a google search for Azzurro (light blue) returns a whole lot of Fulvias in the right colour.
Is there an official Lancia colour chart anywhere that one can look at?
Thanks for all the suggestions so far

I wasn't able to find a comprehensive guide to Fulvia colours. The parts book lists all the names, Lancia numbers and other codes. Nowhere could I find a colour chart with all the colour samples. I googled the different colours and selected paint chips and car colours that seemed right. (when I could find them) I'm not the expert. This is my attempt at making my selection easier and I thought that others might find it helpful. Please let me have comments and suggestions. I'm not sure that this post should be under Fulvia, even though it is about Fulvias, but maybe there is a better place for it. Here is the link

The beginning of a new year! lets hope that we'll get this virus under control soon so that we can return to life as we knew it.
I'm putting my front suspension together and am not sure where all the bits and pieces go on the upper control arm bolt. I know, I should have taken more photos :-\. I'm struggling to work it out from the parts book. Is the order in the photo correct. Thats how I put it together on the right hand side. There seems to be a lot of forward and backwards play on the arm. I'd guess 3 or 4mm in the alu. support frame. I have replaced the rubbers with new


Title: Re: '72 Fulvia rebuild
Post by: lancialulu on 16 January, 2021, 10:12:50 AM
From your photo it looks like you are missing the inner nylon bush that is inside the rubber silent block??

I do not know of a source to one for one replacement - only a modification kit which is different  https://www.pieces-fulvia.com/kit-silent-blocks-upper-arm-lancia-fulvia-serie-1.htm

BTW the nylon disk should be more accurately shaped...


Title: Re: '72 Fulvia rebuild
Post by: lancialulu on 16 January, 2021, 10:14:22 AM
Update

Is your car tubular or pressed upper wishbones. If pressed ignore my post!!


Title: Re: '72 Fulvia rebuild
Post by: Keithver on 16 January, 2021, 10:36:44 AM
Thanks Tim. The arms are the tubular type. The first washer (thin one) at the silent block is a replacement nylon washer. The Pieces modification could be a possibility. The bushes on my lower control arms are the same as those


Title: Re: '72 Fulvia rebuild
Post by: simonpen on 16 January, 2021, 11:10:59 AM
I am confused, I thought S2/S3 cars had 'metalastic. bushes, which I fitted to my S1 in place of the rubber only originals..


Title: Re: '72 Fulvia rebuild
Post by: lancialulu on 16 January, 2021, 11:31:46 AM
So S1 upper is a bar with castellated nut at one end and fixed hex with grease nipple at the other (forward facing). The bar rotates on steel tubes In a 2 part (nylon tube and rubber tube) bush at either end. There is a spacer tube in the middle which allows the greasing to get to the back. There is a nylon washer, a dished washer and a strong washer. The whole assembly is done up tight. Obviously poorly maintained and high mileage cars will wear these parts out which is why there is an alternative with basic silent blocks as original parts seem no longer available.


Title: Re: '72 Fulvia rebuild
Post by: Keithver on 16 January, 2021, 12:09:01 PM
In putting the factory cars together, it seems as if they used up all the remaining stock of S1 parts on older S2 cars and then changed to the correct S2 pieces. I have one of those cars. There are other S1 parts on mine as well


Title: Re: '72 Fulvia rebuild
Post by: Keithver on 16 January, 2021, 04:05:22 PM
Tim, a thousand thanks. Your mention of the nylon inner silent block has saved the day. I make a point of not throwing old spares away until I have that section correctly re-assembled and today that paid off. I went and inspected the old rubber silent blocs and discovered those pesky nylon silent blocs lurking inside. I removed them, cleaned them up and they all look fine. I have put them in and tightened everything up on the RHS. What a difference. No slop at all. Tight as anything. Thanks again guys for your help. The photo shows all the parts in sequence on the bolt

I'm putting the sub-frame back together and wondering how important the torque settings are.
I've been puzzling over pages 11/0010 and 11/0020 in the tech. manual trying to work out which descriptions apply to which fixings. I think I have most of them, but ask for help on the others please.
I have marked up the frame drawing with how I understood the descriptions. Have I got them correct.

Item 5 - is that the single bolt attaching the rear of the 'engine-center-support' to the front cross-member between the alu. uprights?
Item 6 - is that the single bolt attaching the front of the 'gearbox-center-support' to the front cross-member between the alu. uprights?
Item 8 - fixes the 2 steel cross-members to the alu.uprights
Item 9 - attaches the steel leaf-spring housing to the top of the alu. uprights
Item 11 - Is this the engine mount plate to engine. The plate that sits on top of the engine silent-blocks
Item 12 - the 2 bolts that fix the tops of the alu. uprights to the body in the engine bay

She has finally gone off to the body shop for her structural rust repairs. The ones that I'm not comfortable doing. Sub-frame mounting boxes, inner and outer sills, rear wings and the lower patch panels are the main ones. I've asked him to put in a full length membrane between the inner and outer sills. I'm nervous to find out what it is going to cost :o. I'm then going to have to decide what colour blue to paint her.


Title: Re: '72 Fulvia rebuild
Post by: Keithver on 16 April, 2021, 10:00:26 AM
While the body is having all the bits and pieces cut out and replaced, I've been having a look at the gearbox.
I removed the drain plugs as per photo 1. The teeth shown are from the 1st gear syncro. Not sure how this happened as the bronze syncro ring is fine. My box is one of the very early 2nd series boxes and the 1st gear has a 48mm ID rather than the later 47mm ID.

Has anyone got spare 1st gear (41 Teeth, Outer 114mm x Inner 48mm) that they would be willing to part with. I haven't been able to find one in SA. see photo 2.
While waiting for the gear ring, I have taken the motor apart and sent all the bits off for proper cleaning. Then it will go to an engine re-builder to sort out anything not up to scratch.

The other photos show the state of the right hand side with the sills removed. no wonder the jack went up at the rear but the car didn't. ::) From what I have read, it seems as if putting a full length membrane, with some strengthening beads/dimples, between the inner and outer sills is the way to go. Is that correct.




Title: Re: '72 Fulvia rebuild
Post by: nthomas1 on 16 April, 2021, 06:52:40 PM

Reference the sill strengtheners, a number of people recommended to me that I install them.  I could see the benefit in improving strength and rigidity for a track or rally car but wasn't sure whether it would be overkill for a road car.  But I decided that as the outer sills were off the car it wouldn't be that much extra effort or cost to fit them, so I did.  There's some discussion and pictures on the topic on pages 2, 3 and 4 of my rebuild thread (Report on Slow S2 Coupe Rebuild).


Title: Re: '72 Fulvia rebuild
Post by: lancialulu on 17 April, 2021, 03:11:44 PM
Re gears these 1st and 2nd wear badly as the hub does the damage due to inefficient sychro action. See photo. The teeth on the gear wheel get worn to a point where metal fatigue breaks one tooth and then a domino effect. You need to check the gap of the synchro cone to the gear. 1mm is good. 0.5mm bad. You can sometimes swap the less worn synchro cones but I would replace worn ones with new (not cheap). You need to clean out the sychro hubs as well as these gather muck and pack it centrifugally.... Best bet for a replacement would be Cavalittoas breaking a secondhand box will probably reveal an equally worn 1st gear.


Title: Re: '72 Fulvia rebuild
Post by: lancialulu on 18 April, 2021, 10:53:26 AM
cheap gear set from Italy. Vendor is OK but this photo is not! Cannot tell if 1st gear is in good useable condition....

Thanks Norm. I've had a look at your pages and am going to send them to my guy, if that's okay. Those are some mean looking dimples in your membrane. Are you enjoying your car now that it is finished.
Tim, the person that is helping me with the gearbox seems happy with the syncro rings. We have cleaned them and lapped them. I'm not sure who or what "Cavalittoas" is. Didn't have much luck doing a Google search. I have emailed the eBay supplier. I hope he comes back to me. Thanks again for the help. Appreciated :)

Thanks Frank. I can't find 1st gear on the site, but have emailed them with a request. All these Lancia resources I didn't know about. Fantastic - thanks again

Another thought?
would it be possible to machine a 47mm ID gear ring. Taking it to 48mm ID or is the material too hard?

Keith have you sorted this yet? I am perplexed as to 48mm i/d as there is only one hub the gear sits on in the parts book. I measured a set today at 47mm....


Title: Re: '72 Fulvia rebuild
Post by: Keithver on 07 June, 2021, 01:25:37 PM
Sorry Tim. Ive only seen your post now. Apparently, the early series 2 boxes had a 48mm shaft. Later it was changed to 47mm. I got a 47mm gear from Lancia here in ZA and took it to a gear engineering shop. They bored it out to 48mm for me. He said he was pretty sure that the 'case hardening' was thick enough and the gear should be good. Hope so. I hope to have it fitted back in the box one of these days soon


Title: Re: '72 Fulvia rebuild
Post by: Keithver on 07 June, 2021, 02:38:59 PM
Progress at the body shop.
1st Photo shows the drivers inner and outer sills, full length membrane (between the two) and the jacking points welded in and primed. the 2nd photo is the strengthening box we place inside the sills above the jacking points and the third is the cleanup of the surface rust and accident repair on the drivers rear quarter panel. The inner panel was pretty mangled, but Dean has managed to sort it out so that the trim-card next to the back seat now fits properly. The driver's side might even be complete this week.
The car came with a replacement engine (818.302), running, in the car and the original one (818.303) in pieces. I'll be fitting the 303 again, so it will be original. The engine is at the re-builders to have the machining etc. done. The original block had been re-sleeved but not honed. It has now been honed. We managed to reuse the pistons but have fitted new rings. The crank was re-ground for the new main bearings. I have had the valves and guides replaced. Not one of the 4 rocker shafts was serviceable, so have replaced those. The camshafts were fine and so were most of the rockers.
When I get the lot back I can refit the head and work out the timing. I've looked at the manual and, not being a mechanical genius, feel that I am going to have to read it again, a couple of times, to understand what they are trying to tell me. A complete new gasket set is waiting to be fitted. There is very little of the car with me here at home. I'm really scratching about for things to do at the moment. Oh well, I suppose I'll have to start re-furbishing the stainless steel trim and bumpers next.
