Motor rebuild

[edee em]

Anyone ever had an electric motor rebuilt? I have a 2.25hp treadmill motor
that has an amperage short. They told me rebuilding it would cost less than
a third of buying a new one. Any thoughts on the quality of rebuilts or the
process?

Motor rebuilding is viable. Like anything else, it depends largely on the
skill and experience of the technician. Do they offer a warranty?

shorted turn is more like it... what that means is the motor overheated,
melting the laquer insulation on the wires, allowing the wires to touch..

If a motor company does the rebuild, they'll also install new bearings. If
"they" are a motor rebuilding company and they are competent, the rebuilt
motor should work like new.
But don't assume they're going to rebuild YOUR motor. They're more likely
to sell you an already rebuilt motor if they have one in stock, and they
will rebuild your original motor to sell to another customer later on.

Probably rebuilt in Mexico or the like.

That's exactly how it works with auto parts. You buy a part for cost+core
charge and you get your core charge back when you return your old part.

Let's hope his rebuilder is competent.

I try to avoid rebuilt auto parts as much as possible. I've been doing my
own car repairs for many years now, and 80% of the time the rebuilts gave me
troubles. This was across different makes, models, and from different
rebuilding plants.

I never met a rebuilt alternator I liked. The work was invariably subpar.
I'm talking about everything from sloppy soldering to outright LIES about
the parts that were replaced -- underrated diode plates, old regulators
spray painted to look new, failure to replace brushes, etc.
Those miserable potted, dish-type OEM diodes kept giving me probs with one
particular job, so I ended up yanking those and torching in hockey-puck
diodes -- never had anymore probs with that alternator!

Other rebuilts such as a/c compressors and brake cylinders and calipers are
potluck as well.
I see pros walking in with cores and leaving them behind when they walk out
with their fresh rebuilts. Most of them, and their customers, are in for a
major headache.
I hang onto my cores for a few months to make sure the rebuilt's ok.
Learned my lesson the hard way with the first alternator job I did. In that
particular case, the alternator housing didn't even line up properly with
the block, even though the numbers were right! Getting your old core back
if something goes wrong can be impossible, as it was in my case.
