I am replacing my crank pulley and picked up a vibration damper pulley puller tool from Sears. I assume that bolts are supposed to thread into these three holes on the pulley to hold the tool in place while I turn the center stud -- but the holes are much smaller than the various bolt sizes that came with the tool. Am I interpreting this correctly? Does anybody know what size bolts I would need?

 

Won't work like that. You have to have a longer bolt in the crank to have the tip of the center to push against. Also you need 3 6mm bolts to fit the threads on the pulley to pull against, but you'll find that you'll need some huge washers to keep them from pulling right through the holes. Then you will also find that the puller with get caught on the frame rail. It can be done but it's not easy, thats why I only use the OEM puller. But have used one like that in an emergency. Good luck

 

Thanks. The center bolt on the tool has a bigger flat surface that pushes on the center of the crank. So I think if I get the correct size bolts for the pulley holes (and larger washers) it should work. Here's a shot of the backside of the tool:


Do I need the special tools shown in the Bentley to press the new pulley back on? Or is there a way to use some other combination of bolts/nuts to accomplish this?
