Servicing a Denso - Page 2

Has anyone replaced the slip rings on one of these? I opened mine the other day to see if the diode/voltage thing is feasible and my (new) brushes are down to the wire. The commutator was slightly ridged but I didn't think it was that bad so I slapped it back together 3-4 months ago.

Usually, they machine the slip rings smooth on a lathe. You can clean them up well enough with some grit cloth.

Denso rules!! Constant 14.5. 100 amp. Easy to work on and don't get lazy with heat or long idle like a 50 pound Bosch

In your first post, you mentioned you purchased genuine Denso regulator, diode bridge and brush set for $75, may I ask where from since I need multiples of these parts

Thank you

When I did it, I used the following ebay links. pretty sure they aren't genuine denso parts but they seemed to be well constructed and they have worked fine in my alternator.

super easy if you can find the parts locally or get these sellers to ship to you.

Along the same train of thought, ..I'm suspicious of so-called 're-built/re-manufactured' units from even reputable suppliers, and have so far been cannibalizing OE parts from my(Bosch) hoard collection that is running out.
