Some engine specifications

Unread post by kmam » June 14th, 2017, 2:34 pm

I am rebuilding my A2 engine and the workshop needs the crankshaft dimensions/bearing clearances and bearing cap torques. I can't find this info in the manuals I have. Can someone please either provide it or direct me to a publication with this data?

Thanks,

Howard
