mule drive pulley removal

Recommended Posts

IthacaJeff

Hi folks,

Before I go about destroying things, how is the pulley on my mule drive removed. The bearings fried the other day on the outer pulley. There are no snap rings, so I assume it is a press fit. But before I pull out the wheel puller, is there any trick to this?

Thanks, all.

The pulleys are not press-=fit, but they do rust to the shaft after years and years.  I have a 1" slot cut into the end of my workbench just for this purpose. 

Don't hammer onto the end of the threaded shaft...you'll ruin it.  Leave the bigass nut on, them hammer the nut... until the pulleys break loose.

I would have said " Big Honkin Nut"  but you get the idea! :banana-wrench:

I have a "sacrificial" nut that I screw on after removing the original. That way, if you happen to beat the crap out of that nut, you have the good one left to put back on. And remember to leave the nut loose by a couple turns so you have room for movement when you are hammering it.

A little PB Blaster helps too. Worst one I ever had, I let it soak overnight, came back the next morning and smacked it gently with a rubber mallet, pulleys slid right off. Be ready to catch the rest of the assembly.

I agree, always guard your nuts and your shaft    ( threads of course)  whenever swinging a  hammer. The last thing you want to do is flatten either one.

 

 

That would be a BAD DAY.      :(

My bearings in my mule drive are bad too! Mine has a snap ring, which I removed and now soaking in PB Blaster until tomorrow and follow everyone's advice. Where do you purchase the correct replacement bearings?

Still having trouble removing. pounding & PB Blaster. Could the bearing be pressed? ...or keep working at it? Where do you find replacement bearings?

Yay! After several days of PB Blaster soaking, mine came off with only 1 whack! Pic of my pulley removal workbench. Now I have to find replacement bearings. I believe they are 6203 bearings????

6203 Bearing Ball .669"x1.575"x.472"  or  17mm x 40mm x 12mm

 

There is also a 6203 with a 3/4" ID.

 

You will want the 2RS which has 2 seals

      Hey all!
       
      Replacing the drive belt on my 252-h. Anyone know the torque specification for the center screw when I put this pto clutch back on? I know it was on there tight it took a minute for the impact to break it loose. Thanks!

      Hey all,
       
      This pully blew up on me yesterday. Having a hard time IDing the part # or replacements. the 308-8 schematics I've found don't list this part.  Its the pully in the front that runs from the motor to the mowing deck. 
       
      Thanks in advance!

      I need a little part number help.   I'm looking for the part number of the idler pulley that tensions the drive belt on my 857.  The diagram shows the left side of the tractor.  And I can't seem to locate the pulley on the parts drawing.  The bearings have gone out on my tractor's idler.
