I'm planning on rebuilding my Bosch 120 amp alternator. One of the two bearings is a 6304 EHSR 2RS1 c3 - 17x52x17mm
I know the 2RS means two rubber shields. And the 6304 is the size. While the C3 is the radial clearance.
But what does the EHSR indicate?
I don't think you *can* rebuild an alternator. You have to buy either a new one or one that is professionaly rebuilt. If you rebuilt it it will brake within months.
plus its probabley illegal anyway without a license
Extra Hard Spherical Rollers?
I would ask Bosch, not Usenet. GW
Depending on the year it may not be re-buildable by someone without very specific tools. Many newer units use spot welded connections that are made during the build process. Even something that should be simple (like replacing the brushes/bearings) becomes impossible for the average DIYer.
Generally, only hybrid and fully electric vehicles use electrical generation as a brake. ;)
In what country?
Russia.
You're asking a technical question on rec.autos.tech? Don't hold your breath for an answer!
I wish I could help you but this ng is mostly kids talking about gas mileage and not automotive tech speak.
