Would anyone know know the correct size for these shims.
I don't have any to measure but looking at the gearbox I think 35 o/d with a 25mm hole will work.
The usual suppliers stock shims but they sell them individually at high cost, I can buy 10 for the cost
of a single and would rather get a good supply of different thicknesses to use as required.
Thanks.

I have a spare transaxle lying around and the output shaft is 25.4mm-ish (it's a bit dirty) in diameter. The outside diameter of the half shaft yoke is 36.3mm-ish (it's a casting). So either 1" ID and 1 7/16" OD or 26mm ID and 36mm OD.
-
Thanks JB, I'll re-check the measurement I made on my output shaft, looks like 26 id - 35/35 o/d will work fine.

would you happen to know approximately how many shims per side i have a little bit of loose and i want to order shims and roll pins but at 2.50 per shim plus shipping witch is really expensive it would be nice to know
i dont want to dismantle before having the parts
thanks
-
Your existing shims should be in good shape. So measure the slop and order shims to fill it, intending to use the existing ones as well?
-
how would you go about mesuring
cause the only option i see is to take it apart and add shims until it’s a thight fit for the roll pins is there a way to stick in a feeler gage
-
Hold a dial indicator on the yoke, then move it in-out and see how much it moves?

I understand that, I don't like ripping a car apart until I've got everything ready to fix it.
But on buying shims, I bought mine from an industrial supplier and they were relatively cheap, nothing like 2.50 each. If you do a search for something like "shim washer" you should find a local supplier. They are nothing special, a common engineering component. I vaguely remember I bought the minimum order of 10 (?) in 0.005" & 0.010" sizes and I wouldn't have done that at 2.50 each !

I had no shims to measure up in the first place. After measuring up the output shaft and getting some advice
here I settled on 37mm o/d & 26mm i/d shims.
I have purchased 30 shims in various thickness from this place, the cost was £14.00, including shipping, around 45p each;

There will be many similar suppliers in the US, just have a search for circular, carbon steel shim washers.
-
Im also needing some shims but my question is does it matter if they are steel,carbon steel,high quality steel or stainless steel., all as I have seen advertised. btw I was going for 25 x 35 size as I dont think the 1/2mm loss on the outer edge is a big deal.
-
25mm ID is too small.
-
would 37 outside be to big
cause they have 25-36 or 26-37
-
Ideally I would have chosen 26 - 36 if they were available, but having measured where the oil seal sits the 37 should fit, if not it's very easy to take a little off the outside.
When they arrive I'll post up with the results.
-
You're going to buy 150?!
-
no !! was just checking i dont need that much
-
I just measured some that I have, from RD Enterprises.
25.4 I.D., 35 O.D.

Spot on.
It's a 1" ID and an 1 3/8" OD
-
they are not so hard to find to bad it’s not the same for roll pins
-

outer is 7mm x 35mm
inner is 4mm x 35mm
outer placed with closed end towards transaxle, inner opposite.

i have a s2 federal so in imperial it’s the dimensions JB wrote
what do mean by outer and inner ?
the only shims i knew about were the one close to the transmission to adjust so it doesn’t move when roll pins are put in
am i missing something

I think Brian was talking about the roll pins, not the shins, in response to calfkids comment above
-
ok thanks for clarifying i was a bit confused
makes sense so now we have all the measurements we need!!
-
The 37mm o/d - 26mm i/d shims I ordered have arrived, they are a perfect fit.
-
Good news.
