I posted a thread about a tractor transmission that failed because all the cap bolts broke.
The original bolts are around 5/16ish, medium thread (didn't get to the store to measure them). They don't have any strength markings on them. They may have failed because things loosened up. It is cast aluminum case. I'm using locktite when I reassemble.
I want to replace with grade 8 (8.8) but I worry that is too much for the case. Any opinions on this?
There is no service manual for this product (it is throwaway). I'm wondering what the torque would be on these bolts. I know for a car diff it is very high, and I know some diffs (like the mark 8) are made from aluminum. From the poking around I see 15-20ft/lbs for similar tractor units.http://www.bobistheoilguy.com/forums/ubb...24c#Post4106576
