Hello All,
I'll be working on an older Sunforce Marine 600 wind generator in the near future, with an internal noise. I would like to identify what alternator they are using prior to disassembly.
Internet searches and customer support has been futile other than schematic and a parts diagram. We suspect a bad bearing but would like to find the replacement prior to disassembly to expedite the repair. Any insight would be Welcome

Bearings of any size and configuration are normally pretty easy to get, however it is most efficiently done by taking your old one in and having them supply you with a comparable new one.
We just had the 50:1 gearbox (39 years old and no longer built or parts available) for our RF main rebuilt and they had the bearings even in a place like Trinidad.

the parts list doesn't break down the alternator, only the assembly. I was hoping to come up with alt. model (AC-Delco, Hitachi etc.) prior to having to measure the existing bearing to reduce downtime.
Thanks.

I found a YouTube of someone replacing the bearings
