D-12 Brake drum

Ted in NE-OH · Mar 22, 2018

What is the best way to remove the brake drum from the pinion shaft? Is there a set screw?

It is pressed on/shrink fit. Must use a puller and long puller legs and maybe some torch heat to get it pulled off the shaft. Place the new drum in the oven at 350 degrees for at least an hr to QUICKLY install and have a piece of pipe ready to drive it on all the way.

Don't know about the D12, but the B/C is basically the same design and same install... and I has a setscrew to lock it once it is pressed on... I think there is a 1 inch round hole in the case below the drum for access to the set screw.

D-10-12-14-15's all have the same p/n 70239452 brake drum and there is no setscrew.

Got them pulled. The holes in the drums are 9/16 NC which is not a very common thread. Bought some running thread (luckey to find) and made my own puller. Not easy but it worked.
