Went to go change the fluid in my 5lm60 today and found out it takes a large hex style wrench. Bummer, I don't have any hex wrenches that large. So I figured I'll have to hold off till I buy the right hex wrench. But I have no idea what size I need and I don't know if it's metric or standard. Maybe one of you guys knows the size.

Thank you!
 
find a bolt with the right head and tack weld or jam nut nuts on the end. that is what we do on mine. I really do need a proper socket bit though... :)

Thought about doing this but was busy. Bought the right hex bit (17mm) today for a 3/8 ratchet.

Tomorrow I'm going to finally put in the amsoil synchromesh fluid.
