I have an old 49 Farmall Cub that I am fixing for my father. I
replaced the bearings in the transmission. The old manual I found
online says the countershaft bearing retainer should be torqued to 35
ft lbs. The top clutch shaft retainer says to torque to 20 ft lbs.
Before I new this I torqued both to 20 ft lbs because of a bolt
size/torque diagram I found said this is the proper torque for a 5/16
bolt. Will I have problems? Why would there be different values?

The 35 ft-lb figure may be intended for high-strength bolts,
although if they're threaded into a casting it's not likely.
Did the bolt torque chart specify coarse or fine threads? Coarse
threaded bolts will often have lower figures than fine threaded.
Are the higher-torqued bolts loaded primarily in tension, and the
lower-torqued ones primarily in shear? Aircraft bolt torque charts
will reflect that difference.
I had an old Farmall Cub I sold 12 years ago. Still miss it.
