LiftMaster EGJ Replacement Parts — Carwash Gear-Reduced Jackshaft Operator
Genuine replacement parts for the LiftMaster EGJ carwash-duty gear-reduced jackshaft operator. These are the wash-bay machines, built for constant wet exposure, so the motor is the part that most often needs replacing.
The motor is model specific. Six different motors cover the EGJ range and they are not interchangeable — the model number on the data label tells you which one you need. Use the table below rather than matching by appearance; several look identical.
