What is the best way to install the pulley on the crank. I have looked in the achieves and it isn't all that clear.

I know there are two suggestions, one is to heat the pulley and pound on with 3lbs sledge, the other is to use the bolt tread in the crank.

My thoughts: I've been told cranks are " brittle", if you ever dropped one it could crack. Therefore, what would pounding it with a sledge do ? furthermore..would this effect my brand new bearings ?

Thanks again. Brian.

Brian, I have installed several of these. As someone said, there isn't a threaded hole in the crank on A's, B's, and C's. On those I first convince the wife I need to barrow the oven to heat tractor parts (promise they are clean and won't stink up the oven for next dinner). Then I heat them to about 250 degrees as I think if you get it too hot it will damage the oil seal. Then I drive it on as quick as I can with a 4x4 and big hammer. I don't think it is the best for the main bearings on the crank. On others with threads in the crank I pull it on with a bolt. Roger

Thanks to all for the response.

Today I had to go to the Case dealer to get some parts and I asked the guy there about installing the pulley.
He said that they used to have two people install the pulley. One would hold a 6lbs sledge on the backside of the crank at the first point (where the throw is for cylinder #1) this was to take up the pounding and to help absorb the shock. The other person would pound the pulley on with a tool they made and another slegde. The tool that they made was a piece of rod that had been rounded on the end (nothing complicated). He said they didn't heat the pulley, but I personally think it wouldn't hurt.

Anyway,
thought I would share this with you all, and hope it helps more people in the future after it hits the archieves.

Brian.

On my farmall AorB there is no threaded hole in the end of the crank.I have never heated a pulley but I will try it (without the wife around)and a dead blow hammer.

I am assuming that you are talking about the front pully that goes on the crankshaft. This pully also has the dogs for the hand crank to engage into.

Make sure that you have the crank and the inside of the pully hub as clean and smooth as possible. Install the key and line up the pully with it. More than likely you will need to heat the pully so that it expands as much as possible. Put it in the oven and heat it to 350o, this in not hot enough that you damage the new front crankshaft seals. Some penetrating oil will help when you drive it on. I use a round block of wood and only pound on the center of the pully making sure not to hit the outer edge of the pully. It is best to leave the front cover loose so that you can keep from damaging the seal.

GOOD LUCK

Boy, do I NOT like the idea of banging on the end of a crank ( or much else). Make sure there are no dings, ridges, or whatever and draw the pulley on. My humble opinions only.

Hey Dave, are you from Paw-Paw Illinois? If so I have a teacher that lives out there and a relative. For the question, I too agree that pounding on a crank is asking for trouble... I sure wouldn't want to put anything out of alingment! I would go for the heating meathod myself. Good luck! -Brad Wies

When you draw it on, be sure to use threaded rod screwed in as far as it will go. Use washers and spacers as necessary and pull it on with a nut. This avoids the risk of stripping the thread in the crank.

I can't remember what exactly the front of the crank looks like. I know there are the "groves" or whatever you want to call it where the crank goes in. If I put washers over this will they sit square? should I use a huge washer and apply pressure on the "front face" of the whole pulley ?

Thanks for all the replies !
