1951JD B connecting rod question

[Bellwood]

Hello JD pros- can anyone confirm how many pounds torque on connecting rods to crankshaft? Thanks in advance.

Mr Thinker says 63 for the B's and 80 for the 50's. Ron MN

Thank you sir

Why the different amounts if they are both insert type they are the same part number i take all to 75psi

 

[greenmech]

Don't know why, unless for babbit on the B. You know the Thinker is right. Ron MN

 

[Kent Petersen]

No he is not always right

I think I took my B insert type rods (B3201R) to 80 or 85 ft lbs. The insert type rods for the B are the same as the 50. The bolts for the insert rods are 1/2" coarse. I'm pretty sure they're grade 8, so with that in mind 80 ft lbs is about right for the insert rods. The bolts COULD be the same for the babbit rods but I'm NOT sure.
