Product Description

This shunted brush is a carbon motor brush with a shunt wire. It is sold separately, however your lawnmower will have two of these, so you should consider replacing both at the same time. These two shunted carbon brushes are attached to the motor. They are in continuous contact with the spinning commutator, so they tend to wear over the use of your equipment. Replacing these brushes should be part of your regular maintenance. When the brushes are worn, this can stop the motor from being able to turn on or only turn on occasionally. A malfunctioning armature can act much the same way, so it is important to inspect it as well.

I bought a brand new Black & Decker electric mower (MM850) 24 years ago. It is an incredible and reliable tool. I really like this mower. Recently I have an issue with the mower. During cutting, the machine is on and off. I did continuity check of the electric cord. The result is good. The switch on the handle of mower seems working. Please advice which parts I should check? (Some video suggests there might be issue with brushes. How to know that?) Greatly appreciate your expertise and help.

Customer:
Kevin from ALCOVE, NY
Parts Used:
242404-05, 242273-00
Difficulty Level:
A Bit Difficult
Total Repair Time:
15 - 30 mins
Tools:
Pliers, Screw drivers
Lacking power and wheel wobbles
Wheel replacement requires prying the locking ring off, removing old and reinstalling new wheel, then hammering locking ring back on.
Brush replacement requires removal of the plastic housing of the mower, it doesn't come off all the way due to handle still being on but does move enough to reach in and work. On top of the electric mo tor are the 2 brushes under cover pieces. For each brush; remove cover held on by 1 screw, pull out spring retaining holder with brush, cut or pry open old crimp, then crimp new brush to wire, install new brush in spring holder, install in motor, reinstall cover. Final step is to reinstall plastic housing and tighten all the screws.
