My UR stock size lightweight crank pulley is being very difficult and not coming off. 2 of the tech's snap-on tools snapped trying to get it off. The tech is going to have another try at it Monday after warming in up a little bit.

I'm not sure if any locktite was used when the UR crank pulley was installed.

If anyone has any suggestions it would be appreciated! (I don't want to run 10 psi on a S/C application without a dampened crank pulley)

Thx.

 

In case anyone is interested, what is needed is a chain wrench to hold the crank pulley in place. Then, a big breaker bar at least 1.5 feet in length and a 5.0 socket. Then use a lot of force.

3 bent and broken snap-on breaker bars later, the UR crank pulley came off and the ATI damper pulley went on.

My guess is that the softer aluminum from the UR pulley began to bond/fuse to the harder metal, but I dunno.

Don't torch it either or you could damage the crank, crank seal, etc.
