• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

pulley puller

Ok, so I made my pulley puller. I prob. WAY over engineered it. I made it out of 1/2" plate steel. It has 4 perimeter bolts (5/16") For the center bolt, I used a standard puller bolt that had a hole in the center. I TIG welded an 8 mm stud to the end of it. I made a "bearing plate" out of a used bearing and a washer. I'll take pics. and load them. I won't get to try it till this weekend. I hope the 1/2" plate isn't too thick to fit behind the pulley, as I built this with the supercharger elsewhere. Think I'll be ok?
 


Hopefully 1/2" is thick enough not to bend. I originally used 3/8" steel and it bent like tin foil. My second design (above) is now 1" aluminum.
 
wow, what size are your four little bolts? 5/16-3/8? I can't see this thing bending... but, like I said, I never took one of these off. I honestly had to sit and think about how it was going to work.
 
In the above post they are 3/8". That pic is not the current design, i added more bolts to the top section so that firmed it up quite a bit.


It takes 6 tons of pressure to remove the pulley btw.
