Crank Pulley

Postby Mr Joshua » Thu Apr 11, 2013 12:25 pm

I have ordered a crank for our A off ebay. I just got the crank in the mail and am looking it over. I have noticed the crank does not have any threads in the end. How would i install a pulley without any threads?
Thanks Josh

Never had an A engine apart, but assuming it uses a cover similar to a cub, put the cover with new sela on, then using a press to install pulley.
If you are not part of the solution,
you are part of the problem!!!

If you dont have a way to set-up a press in front of it, You could cut piece of pipe, weld cap over the end and use it as a driver, being careful not to damage anything in the process! (I have put in many with this method)---just take your time and use a medium sized hammer so you can keep the blows under control! thanks; sonny

Heating the pully will help. You could also consider taking the crank to a machine shop and having it threaded before you build the engine. I am not a fan of beating on the end of the crank in a fresh engine, but I have. Heated the pully on the wood stove first.

A pulley goes on the same way as a Cub pulley, lots of past threads on here that cover it.

Jim i have found lots of threads with unstalling the pulley using threads in the crank but i cant find anything about not having threads in the crank.

I thought the A cranks all had threads. If it doesn't, I guess you'll just need to heat it up and drive it on. Warmed up to 225 or so it shouldn't be too hard to install.

Farmall C113 undrilled crank.jpg


I thought i'd seen more than one crank not drilled in the C113 engine series. The 1946 B and the Super A were both drilled and i installed them in the same manner as the Cub front pulley. But i remember some un-drilled cranks that had a setscrew to lock the pulley on the crank. Here is what i found on my shelf. The pulley on the right is P/N 6502 DC, the junk crank is 46402 DA, and the set screw pulley is 6502 D. Now I'm sure that the BN I rebuilt a few years ago had the same set screw setup. I'll check it this weekend at Zagray.

If you want this pulley PM me, it'll be reasonable

I believe this crank was out of an early A, but the block is long since melted down. I'll check the BN as well for date codes.

I just got through with replacing the pully on my 1953 Super A. My crank is threaded. I used a bearing splitter and gear puller to pulled the pulley. I drilled a small pilot hole in the center of a threaded bolt and threaded it into the hole through the pulley and pulled off of it. It came off pretty easy. After replacing the gasket and seal of the front cover and painting it, I took a wire brush and polished both the crank sruface and the inside of the pully then sprayed lubricant on both surfaces. Making sure the key way was installed, I placed the pulley on the shaft and gently tapped it on a short way with a large rubber mallet. Then I used a set of the same threaded bolts (different lengths) with an impact gun and flat washers and slowly pulled it up on the crankshaft. Didn't even have to heat the pulley. The only thing is that my pulley and the fan pulley are not lining up. Almost like the crank pulley is not on the shaft all the way. Will have to check later to see. It went on much easier than I had thought it would.

Well I have the same issue as above....no threads in the crank shaft end. I am sure I can get the pulley off but I am really concerned about getting it back on without damaging anything. I thought of chilling the crank while heating the pulley. I was going to try using dry ice to chill the crank and heat the pull up to about 350-400 degrees. What do think??? Should work well I think.

don't heat the pulley past 275 or so, or you may damage the seal as you reinstall it. that is, if your pulley does not have a set screw in it - which it should have

My pulley is the set screw type so it doesn't have the sealing surface on the pulley. I will start constructing the puller tonight...still have enough 1/2" plate leftover from the sleeve puller I made....just need a bit more all thread.
