Abstract

The use of a corrosion resistant oil comprising a major portion having a viscosity not exceeding 25 centistokes at 20* C to coat or lubricate the bearings of an axle pinion drive shaft permitting a more adequate and precise installation.

Claims

1. A method of installing and adjusting bearing supports on axle pinion drive shafts of motors comprising the steps of immersing said bearings in an oil composition having a viscosity not exceeding 25 centistokes at 20* C and installing and adjusting said immersed bearings on said shaft within predetermined limits of prestressing and frictional moments relative to the rotary speed of said shaft.

2. The method according to claim 1, wherein said bearing supports comprise conical roller bearing assemblies having a low ratio peak to valley height of the interacting front and guide faces.

3. The method according to claim 1 including the steps of assembling said bearing in said oil and storing said bearing preparatory to installation.

4. The method according to claim 3 wherein sand oil includes a corrosion inhibitor additive.
