Title: 7th. Series rear shock absorbers.
Post by: JohnMillham on 17 January, 2017, 05:22:53 PM
Does anyone know if the 7th series shock absorbers are the same as the 8th? Also, does anyone have their dimensions? Regards, John

Offhand I think they are - I have several in the cupboard and have used bits and pieces to assemble units - but I will check tomorrow.

David,

Would you mind making some pictures?  I have some shocks but doubt they are correct...with thanks!

Sorry for the delay - distracted.  Yes, they are the same.

Friction dampers are such appealing objects.  What is Lambda-lore for treatment of the disks?

The state of the art now?  https://en.wikipedia.org/wiki/Magnetorheological_damper

Nice idea David but the rest of us get them from Paul Beck and they are made of Ferodo.

And many if us go to Graham Brown, who was responsible for the query in the first place, for some of our Australian friends. Hopefully, sorted now. Regards, John

In the mean time I found that the dampers I received with my are looking different cthen David's , and slightly shorter. (arms are unequal lenght, one 7.5 inch one 8.5 inch)

Are the originals Hartfords?  (readily available, however don't like the powder coated finish)

Or is it better to find old original ones and restore them?

Those are not the same!   Yes, they are Hartfords.  When they are covered with mud it is not possible to see the powder coating but you could always overspray them with something.   No problem with restoring old ones though they are pretty simple with spares from Paul Beck.

David,

Took me a while, but at the moment plenty time to do some Lambda spare part research since I'm more or less tied due to a silly broken bone in my foot...

Is the Paul Nash you were reffering to the Paul from Complete automobilist? (seems they have taken over the business)
Do you have an idea which is the correct type as they have quite a selection...

Many thanks,

Koen

Sorry, my mistake, Paul Beck (twit!) - corrected now, who are at https://www.vintagecarparts.co.uk/products/502m-andre-hartford-shock-absorber-model-502m which is the one for my cars.    I don't suppose the exact arm lengths are that critical but will affect the angle of the shock absorber on the car.  Insofar as choosing from Complete Automobilist I suggest you compare the arm lengths they offer with the measurements I have posted.   The two websites look uncannily similar!


Title: Re: 7th. Series rear shock absorbers.
Post by: Dikappa on 01 October, 2017, 07:13:13 AM
Indeed two identical websites, very weird,  but tel numbers and email adress are the same....so I guess it's one company...

Now they suggest the 302 model (wit(h 100mm disks), based on the pictures of your dampers in this post.

Could you please measure the diameter of the disks David?

As If been comparing the pictures on their website's and then in my opinion the 101 model comes closest (also 100mm disks)

Not easy....

Yes, one and the same company nowadays. Paul Beck took over The Complete Automobilist some years ago and I guess keeps the name alive as for many of us of a certain age they were the only go to people for vintage parts. If my memory serves me right TCA was owned and run by Colin Crabbe, well known VSCC member and vintage car racer. He also tracked down and brought to GB a number of cars of historic interest.

The arms are all 230mm.   The ones in the shed which came with the VIIIth saloon 50 years ago and the ones on that car have 90mm discs.  The ones on the VIIth torpedo which came from Australia and is thus a colonial model with big wheels for ground clearance and rough tracks have 100mm discs.   You pays your money...

Red one VIIth 100mm  black one VIIIth 90mm

Thank you David!!!

In a way this makes it easier, I can go both ways....
I think the 101M-REP looks closest to the ones fotographed earlier in this post, and to the ones on the black car, only they are 100mm, bit of both should also be ok I guess...

I have also just stripped the shock absorber in the third picture and the discs (renewed a few years ago) are wooden, not Ferodo!   Pieces came from Paul Beck.  You will have noticed the missing retaining nut - 7/16 x 14 Whitworth, now unobtainable, so I had to make one.  Now waiting for the paint to dry...

David,

Whilst you have them off the car, could you pls measure the lenght of the bushes?  They offer a choice in 40 or 42mm... (I wouldn't think it would make a lot of difference but if I order, they might well be correct...)

Many thanks,

Koen

Sorry, put it back on now.   If anything I would go for the 40mm as I only have a few threads remaining on the mounting pin.
