Install front pulley

[Charles (49) Mo]

Wondering if a piece of 1/2" all thread (ready rod) is stout enough to pull the pulley back on the crankshaft? How much torque is required? It was everything a 5 Ton jack could do to get ours off. How are "YOU" putting yours back on? Any helpfull hints or tips appreciated.

Hi Charles

That is what I used to put mine back on. I was able to pull mine back in with a closed end wrench. Make shure that you have the wear sleve down far enough it has to go past the end of the pulley about 3/8 of an inch. I used a three finger puller with a bearing seperator behind the pully Iand I didn't think it was going to come off at first.

Did you have to use a cheater bar? If so, how long?

[cowboy]

I did not need a cheater. Put it in gear blocked the tire and used a craftman 3/4," 9.5" long wrench. I would have used a impact gun but I didn't want to cut my rod. The worst part was getting the keyway lined up. It was the only one I have done but I not have a problem with it.

Charles, heat the pulley in a 300 degree oven for about 20 minutes before trying to re-install. It should pull right on.

Have an old electric roaster that should work nice.

...and prior to heat and assy, make sure you have filed any high spots or dings from the crank and the pulley I.D. use a fine file or emery paper, and holding a file on the crank while the engine is running don't count ! take off only the high spots- don't reduce or enlarge the part sizes; clean all gunk off both the crank and pulley I.D. Use some carb cleaner or equiv to take any varnish off. NO SMOKING cleaner and scotchbrite works good.

A little humor in above post --- A novice might not pick it up and get hurt. NEVER try to file the crankshaft with the engine running. Besides a lot of oil coming at you thru the open seal-crank area, a file might get caught and start moving at you like a bullet.

I put my pulley on this winter, and besides heating the pulley, I left my engine outside overnite at below zero temperature and that helped a lot.

OK, now for my stupid question. You are using a puller, threaded rod, etc., to put the pulley ON?

I'm trying with little success to envision this proceedure. I remember studying John's puller to get a pulley OFF in some detail, because sometime in the not too distant future I'll want to get mine off. Now I've not worked on a Cub pulley before so maybe I'm missing something, but without this post I think I would have used the mallet and 2X4 approach to get the pulley back on. But I'd like to know how to do it right.

Can someone enlighten me please?

1/2"x13 all thread is screwed into the front or the crankshaft ( its threaded) pulley is placed over rod on crankshaft, then Put a heavy piece of steel with a 5/8" hole drilled in the center over the rod, against the pulley face. A Nut tightened on the rod pulls it against the crankshaft, pulling the pulley on.

Slappy, the all-thread rod and a piece of heavy flatstock or angle can be used to pull the pulley on. Thread the rod into the end of the crankshaft, place the heated pulley onto the shaft, slide the stock onto the all-thread and place a nut on it. you can then use the nut to "pull" the pulley onto the shaft.

Slappy, dribing the pulley on with a hammer, cna damge the main beairng on the crnak that has the thrust lips on it.

Aaaa... now I see. Thanks guys.
