I need to replace the bearings in my powerdyne. Does any have the part # for the good bearings. I tried the search feature with no luck. Thanks for the help.

 

This is for the people to do it for you (the SKF ceramic costs more)

This is the kit to do it yourself (the SKF is an extra $125)

Another source to try is 928motorsports.com or 937 - 287 - 9875.

 

I bought my pulley from 928. Good service, nice product

 

Powerdyne is now using SKF ceramic bearings for the small ones they went from a shielded to a special sealed bearing with a special lube here is the actual bearing number SKF 6202-2RSTNH/HC5C3WT the large bearing is A SKF explorer series 6205-2Z/C3GJN I installed these bearings over 2 years ago and most of the time I am running a 2.5 pulley at 10# of boost I did go to a 2.7 for the cold months do to a small amount of ping at shift points. this is a daily driver. and these bearings have done well.
I will say that the bigger problem with the powerdynes seem to be that they miss machine the shafts and to get around this use bearing locker as a means of holding the bearings to the shaft. when the hot weather hits the bearing becomes loose on the shafts and this is the actual noise you may be hearing. If you don't get a good press fit you will have to repair the shaft or find new ones and use a better locking compound. I use permatex seat and sleeve retainer it holds up to 450 degree temperature. If you find this problem and the bearings are still good try this product, it will need at least a 24 hour cure time.
Koyo also make s a good bearing 3NC 6202-ZZC3FG5GSR I have heard good results with those also. Good luck if I can be of any help feel free to email me direct These are not hard to work on and I will give you any tips that I can.

 

Any questions definately ask ChucksBP. I took mine to a machine shop and they cracked my case trying to remove the blind bearings. Luckly it was in a spot that did not hold any stress and I repaired it. Chuck came up with a way to remove the blind bearings by drilling from the back. It worked perfectly for me even with a cracked case (had to get the bearings out to fix the crack).
Good luck and after one rebuild you will be an expert and will no longer worry about your Powerdyne. If you find a (less expensive) source for the bearings then share it with us.

 

Thanks for all the good info guys
