Timken SP500301 already bad

[Dustin Jackson]

@petethepug I had to return the bad one as part of the warranty process. What is this about SLF bearings?

 

[petethepug]

SKF bearing are the go to standard for bearings. Use them in my supercharger and alternator hubs on the VW. I was losing alternator bearings every 2-3 years until I had a rebuild shop rebuild my Bosch fact rebuilt alt with SKF bearings.

Even the Bosch Auth factory rebuilt bearings were junk or being rebuilt with comprised cores. Both have been going for 10+ years w/ the SKF inside.

@petethepug Thanks for the info. On a side note I did some digging and it looks like my Korean timkens are rebranded iljin bearings. I guess they are some OEM manufacturer out of Korea.

@petethepug Apparently iljin makes bearings for SKF and Timken so hopefully that is a good thing. Time will tell again, sooner or later

Those hub cores are worth a fortune. With the specialty device to disassemble it and cram a new generic bearing in there I’ll bet they’re net‘g about $100 per unit rebuilt.

When you disassemble it, you'll find a pair of opposed tapered roller bearings, or possibly angular contact ball bearings, with a shim between them. This shim controls bearing to race clearance, and is a critical dimension. Be certain to replace them with an matched set as came out, or have the knowledge and parts capability to measure and set end play for an unmatched set.

I won’t be taking anything apart this time, the bad part is returned as part of the warranty process. Sent the made in USA back and have the Korean installed currently
