Taking the 3.8 pulley off SC was real hard for some reason and the bolt on mypuller cross threaded by the pressure, I did get it off but could not use the main puller rod to put the 3.5 on so I am left with a 3.5 pulley that needs to go on another 1/4 inch spent half the day on this pretty frustrating now I have to somehow fix the puller bolt and nut or get another.Any suggestions , any other way to push it on last 1/4 inch.

so you do or do not have the connector bolt cross threaded still in the snout? pics might help

Who'* puller/3.5 pulley did you buy? Take a pic of the inside shaft threads and post it. If you have enough threads left, you can use my ZZP puller to get it on the rest of the way.

Sounds like the puller shaft bolt finally gave out.

Having the ZZP puller myself I know they sell parts and the pullies being press fit, are tough to remove.

As long as you used anti seize and the puller was not new, I think it finally had it. The main bolt is hardened and fine thread because of the force that it must endure. Parts are sold, because things do break.

Thanks guys just the main pulley bolt had the nut stripped on it from the pressure pulling off 3.8 pulley luckily it came off at same time and I did buy puller used.However Sc shaft was ok but now I wasnt able to put 3.5 on.Today I went to work at the steelmill and a millwright there was able to get the nut off and rethread the bolt, and got me a new nut.Tonight after work I was able to put new pulley on thank god.Thanks for replies and EXPIR thankyou for offering your puller and thankyou millwright.BTW it is a pulley boys puller,guess Il need new parts for next time...... did I say next time.
