Is this for Aprillia only, or for all models? if for all models I think it might get a bit unwieldly, so it might be worth opening a new thread for each model technical information, as and when required.

Owners of S1 Aprilias should find Noel's website of great interest. The combination of photos, drawings and text are a great medium for ex[plaining a complicated mechanical issue while showing off the jewel like qualities of Lancia's engineering. I think this website is a terrific template for the sort of thing that most of would like to do, if we only had Noel's skills. Noel has a big advantage on most of us having had a career in the I.T side of film and television.

Of particular interest to myself, is the list of 1st Series production changes he has extracted from the parts books. I own a late S1 car (38 7308) and have been scratching my head for years trying to make sense of the myriad small differences between this car and the majority of the other S1 Aprilias I am familiar with. For instance there are few parts interchangeable between the front ends on the early and late S1 cars, and you will need different tools to service them. In fact I notice changes to virtually every body panel and many mechanical components.

I will be looking forward to Noel's next update on fettling his car.

Andrew

Aprilia gearbox casing.


Title: Re: Technical information only
Post by: davidwheeler on 18 February, 2011, 04:15:11 PM
Gearbox tips.

To remove the gears it is necessary only to remove the front bearings.  After having removed the front and rear plates, remove the locating plug for the input bearing and the rear nut from the layshaft.  Heat the front plate of the gearbox (inside the bell-housing) to 90C.  The input shaft and its bearing should pull out or at most need a gentle tapping on the output shaft to dislodge it.  Rotate the gears until the detent pin 382008 is pointing downwards.  The output shaft may then be pushed out forwards.  Take great care not to lose the detent pin, it falls out inwards.   Now tap gently on the rear end of the lay shaft.  This should dislodge the front layshaft bearing (no retaining pin for this) and the shaft should push through the gears.
There are two types of bottom gear pinion.  One has a 28mm shoulder on one side and is flush on the other.  This goes with a 32mm sleeve.  The other type has a shoulder of 13mm on one side and 17mm on the other.  This goes with two 15mm sleeves.  The total length in either case is 73.5mm.  The bottom gear pinion has thus two possible positions and must be put in the REARWARD position.  The layshaft may be reassembled (note carefully the position of the washer  38.20012) into the gearbox case and the front bearing inserted but not fully driven home.
Next the output shaft may be installed, threading it through the gear cluster.  Some output shafts 3820001 have one spline that is different from the others.  This MUST be assembled in line with the detent pin.  The other version has all the splines the same and is indifferent.  Install the detent pin and retain it in the outer end of its hole either with grease or gravity or the shaft will not go in.  The bottom gear wheel 38.19517 has a different internal tooth which must line up with the detent pin (if you get it wrong there is room to wriggle it round with out taking out the gears.  Similarly, make sure it does not slip round into the wrong place).
Heat the gearbox again and fit the front layshaft bearing (not too tight) and then the input shaft, lining up the groove in the bearing with the hole.  Insert the retaining plug.
Fit the selector rods and locating balls and springs, hold them down with a metal strip and test all the gears.  If you are very lucky, they will all work!


Title: Re: Technical information only
Post by: davidwheeler on 20 February, 2011, 04:29:05 PM
Re-installation.

Make certain the gearbox is in neutral.  In some cars it is possible to install the gearbox with the engine in situ; in others it is not.  Install the gearbox in the car.  (Retain the clutch spinner in position with a rubber band to facilitate engaging the withdrawal fork).
Unscrew the gear-stick from the operating goose neck 58-0152R.  This latter should then slip into place and lie in the neutral position.  Do not try to force it.  Install the spring and retaining cover 38-21504-6,  screw in the retaining screws 38=21507 and only then screw the gear stick back into place.  Attempting to install the gear stick as a whole will displace the selector mechanism and make gear selection impossible.  Check that it works!

This Houdaille stuff is for the other side of the pond. I suspect all Euro applications use castor oil instead of glycerin. If castor oil has been used as original fit then any other fluid mixed with it will turn to a gooey mess and stop the damper from operating...

I think Ben Courage will be taking Noel's car for a drive tomorrow and I will be interested to hear what he thinks of the way the shockers damp. Ben has been driving the ex Stainless Stephen car around for the past week or so on the Castlemaine Rally and other adventures. Ben thinks the Stainless Stephen car is very similar to his own car, but the damping on Noel's car is very impressive with no nasty whacks and bangs over speed humps and other road hazards. Mind you it did take Noel a fair bit of fettling to get the car to that standard.

 On a different subject Gerald Batt ran his newly acquired ex Lance Milne 1948 Berlina on the rally and looked to be be enjoying himself. Seven Aprilias appeared on the rally which would be a record although perhaps my bodyless platform chassis only qualified as a half a car, but it did manage a couple of very enjoyable laps of the Castlemaine oval on the Saturday and Sunday. Other U.K Aprilia owners should seriously contemplate a visit for the 2013 Rally.

Cheers
Andrew

I did indeed take Noel's Aprilia for a run when I visited him last week, having driven there in Andrew's.
The first thing to say is how generous and trusting the Australian Lancia owners are! I have now done several hundred miles in Aprilias on this visit, including Castlemaine where there was the usual fabulous turn-out of Lancias, especially Lambdas as well as the aforementioned Aprilias.
Comparing the two cars is tricky as Andrews is still in "shake-down" mode after many years off the road and I only drove Noel's briefly. Both have the familiar Aprilia feel of handling precision and sure-footedness. The initial harshness over bumps in Stainless Steven was improved quite a bit by reducing the tyre pressures from 33 down to 26. Arguably this may still be on the high side as the handbook talks about 21psi! I run my own car at 26 (with 165x400 Mich. X's) as the steering gets heavy for low speed maneuvering at any less than this.
On Noels car the steering,although precise, was heavier than expected and we diagnosed excessive toe-in so it will be interesting to see if it responds to being reset.
On SS there is some vibration at speed that is hard to pin-point with one of the rear wheel bearings being a possible suspect.
Overall both cars perform well but the bigger carb on Noels does give it a distinct advantage.

Finally thanks again to Andrew and Noel for letting me drive their cars and thanks and congratulations to the Castlemaine organisers for another brilliant rally


Title: Re: Technical information only
Post by: davidwheeler on 01 November, 2011, 09:11:14 AM
This is getting dangerously near chat, not what this thread is really for.  However, two technical points.

Tyre pressures.  I run mine at 26psi on 155x400 Michelin X and wear seems evenly distributed across the tread.  I agree, lower pressure = heavy steering.

Andre Telecontrol fluid.  Glycerol as stated in the instructions is actually an early form of antifreeze, now superseded in cooling systems by ethylene glycol (which has a lower freezing point but is poisonous).  I see no problem with using blue or even the more modern orange antifreeze mixtures.  The point is that the working fluid is aqueous not oily.

Just caught this as I have a variety of plugs in my engine (still goes well). Most are B6S NGK's, one is a Bosch W8AC which is definitely wrong, but Bosch equivalent W175T3 is alos available and is curiously like the M.A.B.O. W. 175 T3 in the series 2 maintenance manual.

I think I will stick with the NGK's as they have always worked (as a plug type - not specifically!) well in my fulvias, and they are cheaper.

Tallow used to be recommended, but I find common or garden grease works just as well. I have tried soaking the discs in oil, but the wood they are made of isn't absorbent enough.

I have used NGK B6S  Ade.

The NGK website  http://ngkntk.co.uk/index.php/downloads/   lists B7S which is a slightly softer plug.   I was having trouble with fouling plugs with B6S so I have changed them.  So far so good.
