fan puller

Hi, this is Martin in Ohio.

I'm rebuilding my waterpump for *A 11739 *.

Now the fan is stuck on the pump shaft. It's been apart already, but I goofed in putting it together this time.

Does anyone have a recommendation for a tool to pull the fan.? Looking for something I could acquire at parts store or Sears that will pull the blade off the shaft, while keeping damage to minimum.

Don't want to pound on this unit as it is all repainted and refinished. Just want to make some adjustments and replace the fan.

Thanks for helping with my goof.

Regards,
 
Martin: Have you tried "gently" pushing it off with an hydraulic press? Thread the knock off tool on to the shaft and just be real careful. The nice thing about presses is that you can apply a moderate force on the fan hub and just leave it for a few hours. Eventually it should let go without damage. Good luck.
 
the Model A steering wheel puller works quite well on the fan -- just remember to thread a nut on the shaft to protect the threads.
 
I should have explained more details.

My waterpump has a leakless conversion, and in this case has a circlip at the front of the nose end on top of the bearing, holding the shaft in a stationary position.

Because of the circlip, "pushing" the shaft out of the pump from front to back(and out of the fan blade) is not an option.

The only way is "pull" the fan off the front. Then the circlip can be removed and the shaft taken out. Is there any readily available tool that will do this?? I'm hoping for something really simple that I can find without too much searching.

Thank you FB
 
Thread a nut half way on the end of the shaft, then thread a short bolt into the othe half. Hold the fan hub in one hand while you strike the bolt with a hammer. It should come loose with no problem. Do it over your lap or low to the floor over carpet.
 
Remove one of the lock nuts from your kingpins and thread that onto the end of the shaft for tapping.

While this would also work, it might be better to use a small ball bearing inside so the hammering pressure is on the shaft rather than on the threads.
 
The vendors all sell a "Tool" that is just a fat closed nut that does what Tom's two nuts do. You screw it on and give it a rap with a hammer, and VOILA, off pops the fan !
 
Go down to your local hardware store and buy a bolt and two nuts that are the same thread as the pump shaft. As Tom W. said screw one nut on half way, then screw the bolt in the other half so it is up against the shaft, then screw the second nut down to lock the first. Let the pump dangle between you knees with something soft underneath to catch the pump. Smack the end of bolt with a hefty hammer.

Put the new tool in a plastic bag with a note as to what it is for and keep it in your Model A tool bag for future use.

Thanks for all the nutty advice.

The fan is now off the shaft, due to the nuts being correctly positioned.

A good few whacks with a hammer on the shaft and the nuts did their job.

I am nuts about this forum.
