Alternator Rebuild question


Well-known member
I have a failing bearing on my alternator (14cux truck). I separated the alternator and the bearings are out. Part #s on the bearings are 60030w and 63030. Is there a particular brand of bearing I should use or stay away from? My first time rebuilding an alternator so I'm not sure on where to buy.

i think you have an extra digit in your bearing numbers. also NTN,SKF,FAG,RBC,Timken are all good brands

where its made is semi-important US/JPN/FRA prob being the historically best quality

grainger/mcmaster for sourcing
