Is there anything special about the washers for the M12 transaxle mounting bolts (i.e., thicker, larger OD)? Part number: 914-375-239-00. #39 in parts catalog diagram.
They appear to be NLA and I can't find a description or photo of them. Washers I have are 13 ID and 27 OD. Normal thickness.
Thank you.

Yes, they are special thick washers. Pm Bruce Stone I'm sure he has a few hanging around.

Sigh. Thanks. Good to know.
If anyone can share the spec that would be greatly appreciated. I'm going to install the engine tomorrow. I have a bag of thick washers I could potentially modify if I knew the correct thickness and OD.
I recall them being about 3/16" thick. Good luck.

Thank you! I'll add this info to the parts vault.
The one's I made were 41.7 mm OD, drilled to 12.7 ID, and a 4 thick washer. So I'll probably roll with this for the foreseeable future.
