Why is it so hard to find..

parts for the GM CSxxx series of alternators? I need bearings and brushes and all the parts stores are saying they are not available. They tell me I can't rebuild them. The rebuilders are rebuilding them, so where are they getting their parts? Does anyone know where I can get parts for these alternators?


I get mine from the rebuilders.

You can buy a kit from Summit Racing to modify and improve the CS alternator. The kit is made by National Quick Start and contains a larger rear bearing, a finned housing (for better cooling) and other parts necessary to repair the alternator (except the front housing and rotor). There are two kits, a standard kit and an upgrade kit that increases output to 140 amps.

This kit requires a press, gear puller and very good soldering skills. It IS NOT a kit that is meant for the totaly unskilled person to install

- it requires a good level of skill. The kits cost $50 for the standard kit and $100 for the 140 amp kit.

There are a number of aspects to these alternators which make them a real pain for a DIYer to rebuild them (they're not considered field rebuildable), so few people want to try, therefore the limited supply of parts for them through regular DIY sources..
