Product Description

?

This is a genuine Powermate replacement part, it is sold individually. • Worn brushes frequently are the cause behind a motor running poorly. • Replacing brushes can fix a motor that's operating intermittently. • New brushes can restore a motor's electric braking. Carbon brushes are one of the most commonly replaced power tool parts. This is because carbon brushes are wear items, meaning that through friction and use they will gradually wear away until they need replacing. Worn brushes are a common causes of intermittent motor function, reduced electric braking and reduced motor power. A worn-out brush will often be worn down near to the wire lead and can be cracked, pitted, or burned. When replacing carbon brushes, be sure to inspect your armature for burns, cracks, or other damage which can indicate larger motor problems.

When our generator stopped producing electricity we removed the back housing from the generator finding one of the 2 brushes completely wore out. Upon purchasing replacement parts from ereplacementparts.com they were delivered timely as promised. We replaced the brushes, reassembled the generator. The generator now runs perfectly like it was intended to. We are completely happy with our purchase and customer service!

Coleman Powermate Generator Model 542000 stopped making 110v power

Removed generator rear power cover with #11 socket wrench and #11 box end wrench \"4 bolts\"
Removed both diodes with small socket wrench and snipped each wire close to diodes solder connection. \"Diodes are threaded through bottom of power cover\"
Stripped about 1/4 inch from both wire ends and soldered to both new diodes and installed the new diodes back onto the power cover with the original nuts.
While the cover was off added grease to the roller bearing and cleaned the smooth area where the brushes make contact on the exposed armature.
with a small flat blade screwdriver, removed both old brushes at the front side of the power cover and replaced with new ones.
Be sure that (all wires are firmly attached to their connections) and reinstalled the power cover to the generator body.
This has repaired the loss of power production for this Generator.

Tested outlets with multimeter.
Beautiful 120 volt output, just as required.

Good as new.

I removed the old brushes and checked for wear. They were seriously worn down. I could get nothing when checking the bridge diode for voltage resistance when checking matching wires. The rotor tested good output when I tested both copper sides. I replaced the brushes and bridge diode with new components from eReplacementParts.com. Wh en the generator face was replaced, I started it and checked the output. It was operating perfectly. This was on an old Coleman Powermate, model OHM110-222712c 6875/5500 watt generator with an 11 hp Tecumseh engine that I had purchased in about 2003 and has seen a lot of use. It appears as though I will be getting more use out of it in the future.
