C7493 Gearbox spacer

[Mark J]

Hi Everyone,
Well finally starting to put my series 3 together.
The gearbox mounting spacers have gone for a walk, I don't seem to be able to get them from the usual sources.
I would be grateful if anyone has the dimensions so that I can replace them with a standard part.
An odd ask I know, but all help much appreciated
Mark

Hi Steve
Thanks that helps
Given that the bolts are 5/16 UNF , does 9/16 thick , ID 5/16 and OD 1/2 seem right. Or should the OD be larger?
Best
Mark

Sorry.. can't give you any more info than the photo and dimensions as in the link..your dimensions dont sound correct when looking at the photo...Steve

Hi Steve,
9/16 wide, 7/8 OD and 1/2 ID looks more like it.
Thanks again
Mark

The original posting referenced in post #2 by Steve was mine.
I made two errors (I fat-fingered a couple of numbers while using the numeric keypad on my laptop).

Here is my correction that I posted about 6 entries below my original:

QUOTE
The average thickness of the 5 spacers = 0.2818 (between 9/19" and 19/32")
The average thickness of the 5 oval washers = 0.100" (abt 3/32")
The average thickness of the 5 lock washers = 0.0836" (abt 3/32")

Sorry for the double error; the above is my original posting
What is posted as “5 spacers = 0.2818” should be “0.5818” (fat-fingered the 2-5 on the number key pad)
What is posted as (between 9/19" and 19/32") should be (between 9/16" and 19/32") (fat-fingered the 6-9 on the number key pad)

Sorry for the confusion

I still have yet to install my transmission so these spacers are still on my shelf.
Let me know if you want any dimensions - new ones or additional corrections/clarifications to old dimensions

In your initial post, you said:
" I don't seem to be able to get them from the usual sources."

I managed to lose one of the spacers but used SNGB for the missing one. It was on backorder when i ordered it but came through about three weeks later. The benefit in an SNGB one is that it will be plated. I doubt a workshop would go that far.

Just checked SNGB website and they are still "Backorder" but try it

Forgot to say, C7493 is now C32458/2 so search for that
