JLG | Compact Crawler Booms X33JP - Electric Motor Maintenance
Use this checklist inspecting and maintaining the electric motor. Electric Motors that are not properly maintained will degrade over time and require premature replacement.
Periodically check the condition of the following electric motor components.
Electric Motor
The electric motor is located inside of the rear hydraulic valve distributor support cover (AC Lithium) or inside of the ground hydraulics compartment in the center of the chassis (Bi-Energy).
POWER SUPPLY TERMINALS
Check tightness of the nuts on the power supply terminals and make sure the insulation is intact.
FAN
Keep air intakes clean and make sure the fan can rotate freely.
BEARINGS
Check the condition of the bearings, in the event of noise contact JLG for replacement, the life of the bearings is reduced significantly in heavy duty operating conditions.
NOTE: This motor is "brushless" therefore no brushes need to be checked or replaced.
