DC 5000 MOTOR AND WATER PUMP MAINTENANCE

Lubrication

The DC 5000 motor and the March water pump are supplied with lifetime lubricated ball bearings.

Brushes (Leeson Motor)

Motor brushes need periodic inspection and replacement as wear indicates. Brush wear is greatly influenced by individual application, voltage and heat load. It is recommended that brush wear be checked at early intervals of operation in order to determine future required inspection.

With daily use of the DC 5000 as a primary system make an initial inspection of the brushes after:

Single plate refrigerator

6 months

Multi-plate system with freezer

3 months

Standard Leeson brushes have an initial length of 1 ¼”. When brushes are worn to a length of 5/8” they and the brush springs should be replaced. Operation of a motor with brushes shorter than this will cause the brushes to jam in the brush housing, arcing and wearing the commutator. A worn or damaged commutator will accelerate brush wear and further damage your motor. It is normal for one brush to wear more than the other. Check them both.
