RECOMMENDED LUBRICATION PRACTICES FOR
AXLES AND GEAR BOXES
MS= Single tires MJ= Dual tires P= Drop wheel
DELIVERY
The machined unpainted parts are delivered greased and must be used as delivered.
The gear boxes and axles are delivered without lubricant.
The wheel hubs are greased for life.
LUBRICANT FILLING
Lubricant Quality
We recommend a multigrade lubricant 80 W 90 with service level API GL 5 and approved as
meeting US MIL L2105 C specification. All lubricants used must be compatible between
them.
See our specification STC 5-101.
Avoid mixing two different oil types, even if from the same trade name.
Checking and Filling Procedure
The unit or the vehic!e must be on a level floor. Fill the unit through the oil plug until overflow.
Lubricant Capacity
Lubricant capacity are given as guideline only: the oil level only determines the lubricant
capacity needed according to the unit.
Axles
The oil capacities vary due to the vehicle manufacturer’s installation, or to the length of axles
where the lubricant flows from the differential carrier through the planetary hub reducers.
The oil capacities are usually constants for a given differential carrier 1 250 - 1 500 1 600 - 1
750 - 1 800 (except for 1 800 DG).
