front pulley on AV stuck

Postby housebg » Sun Mar 20, 2016 4:33 pm

Hello I am trying to pull the front pulley on the AV it has been setting up for ten years waiting on my retirement to get a face lift . I seen the wheel puller in the section on cubs .Is this required on a AV also and if so would anyone know what size bolt goes in the crank shaft. I have to get pulley off because it has three or four breaks in it .

Some A pulleys have a setscrew, others not. Either way, once the setscrew is loosened the process is the same as you have seen described here for a Cub.

Wire brush and a spray can of brake cleaner to clean up the back side of the pulley.
I have an excuse. CRS.

You're going to have to get it cleaned up by whatever means necessary to determine if it has a set screw.

If you can get the right sized bearing separator and a large 2 or 3 jaw gear puller, you can get the old pulley off by heating it. Heating will require an oxy-acetylene torch or at least three propane torches.

Since you're going to replace the front engine seal anyway, the heat won't matter, and it's a whole lot more civilized than a 12-ton hydraulic jack and brute force. I just cringe to think how much energy is stored up if your puller rig lets go with 24,000lbs of force on it.
