Hello All
I am fitting a 3304 into my 955K that has the later style 955L coupling on the flywheel. As I only have the 955K's workshop manual I don't have the torque settings for the bolts in the flange. Bolts are part number 4 (1A1460) in the pic below.
Also I could not find in the manual the torque setting for the flywheel bolts.I have 118-142 ft lbs from the 944's manual. Is that the same for the 3304? Bolts are different lengths but the same diameter and thread.

Regards

Phil

Coupling bolt torque is 80 ft lbs
Flexible coupling flange (part #'s 6P3983,6P3984.6P5020] bolt torque is 95
Two piece front flange center bolt torque is 160 ft lbs
Dont have flywheel bolt torque, must use standard bolt spec torque.

Thanks Rome but mine is a single piece flange.Do you know what size bolts are in the two piece flange?

The bolts for the rubber couplings are 6H1717 1 1/8" 1/2" coarse grade 8
Bolts for the front flex plate are special high strength bolts 0L1329 3" 1/2"coarse
Recommend getting bolts from Cat.

Thank you very much Rome

Your welcome!

On the subject of fly wheels; we are putting a D315 back together. what is the torque value on my flywheel bolts?
We torqued the bell housing nuts to: 150ft lbs.

Use the bolt torque setting for that size and thread bolt. No set torque ratings are given for flywheel bolts in the manuals.
