Crush Washer Dimensions?

[Steve W10]

Hi all,

I have been searching for well over an hour now, including what seems like every forum entry, the 101's, "Replacement Filters, Belts, and Lubricants", FAQs, including "ENGINE FILTER / FANBELT / AIR INTAKE EQUIVALENTS" with zero luck.

Anybody have some dimensions for the engine and transmission Crush Washers?  Inside and outside diameters, thickness?  What I read says they should be aluminum; is copper okay?  Any help would be greatly appreciated.

My crankcase drain plug is leaking, and I really should do the transmission oil.  Just trying to save multiple trips to the boat.

Thanks in advance.

Steve : I'd suggest that you go on-line to someone that rebuilds Hurth transmissions and obtain a few of the crush washers that fit the bottom drain plug.

Steve,

I have Hurth parts manuals.  I can't post on the TW -- been looking for procedures where/how to upload PDF manuals.

So ping me if you want them.

Thanks guys,

Surprised no one's got one lying around to measure.  Guess I'll have to order them rather than just getting 'em at my local car parts place.

Ken, not sure which manuals you have, but if it's not too much trouble I'd certainly appreciate them.

If email would work, please send them to stevew10@hotmail.ca

Thanks,

Steve

Steve,

Done.  I sent 2, I thought I had another -- still looking for it.

Ken, thanks much for those, interesting stuff.

Dave, thank you too.  I'll likely zoom by my local guys and pick some up.  I think the 16mm is the critical number.  I'm assuming you've used those and they fit well.

Thanks again guys.

Welcome Steve.
I just uploaded a searchable PDF of the Hurth manual to the TW manuals page.

I actually order 14mm to begin with and had to file them out, but worked fine.  Don't ask   From that detail work found that 16mm was the correct size.

[Steve W10]

Thanks Dave, I'll grab a few of those before heading down.

Really appreciate the insight, thanks again.

Thanks to Loren Beach.

I put it in the wiki, too.

This washer with a rubber seal bonded to the ID is at McMaster-Carr good for up to 225F

Bolt   ID     OD   Thk min/max     qty        p/n          $
M16   15.7   27.1   1.1       1.4   5   93786A250   11.98

If this don't work possibly one of the SAE sizes would. 
5/8"   0.683" 1.187" .089"-0.099"   5   93781A035   14.32

I plan to order a package when I get to needing new washers.  Unless someone out there has a "no no" about this idea.
