Maintenance: Grease Fittings
Bearings internal to the electric drive motors are sealed, and you do not have to grease. The reducer on the electric drive unit is grease packed and should not need to be greased until the unit needs to be overhauled.
The manufacturer recommends an overhaul every 20,000 hours or four to five years. This consists of disassembling the unit, replacing the seals and gaskets, cleaning the internal parts, and then repacking the unit with designated grease (Exxon Unirex N2 Grease).
Below is pictures and a video showing all the bearings that our ops team recommends greasing.
