If you use cleaning solvents, hot solution tanks or
alkaline solutions incorrectly, serious personal
injury can occur. To prevent serious personal
injury, follow the instructions supplied by the
manufacturer of these products. Do not use
gasoline to clean parts. Gasoline can explode and
cause serious personal injury.

parts or surfaces. Kerosene or diesel fuel oil can be
used for this purpose. NEVER USE GASOLINE.

Remove gasket material from parts. Be careful not
to damage ground surfaces.

DO NOT clean ground or polished parts in a hot
solution tank, water, steam or alkaline solution.

Clean Parts With Rough Finish

cleaning solvent or in a hot solution tank with a
weak alkaline solution.

Clean Axle Assemblies

•
A complete axle assembly can be steam cleaned
on the outside to remove dirt.
•
Before the axle is steam cleaned, close or put a
cover over all openings in the axle assembly.
Examples of openings are breathers and
hydraulic inlets.

Dry Cleaned Parts

•
Dry the parts immediately after cleaning and
washing.
•
Dry the parts with soft clean paper or rags.
!
CAUTION
Damage to bearings can be caused if dried by
rotating with compressed air.
•
Except for bearings, parts can be dried with
compressed air.

Prevent Corrosion

•
Apply axle lubricant to cleaned and dried parts
that are not damaged and are to be assembled.
•
Apply a special material that prevents corrosion to
all surfaces. If parts are to be stored, wrap the
parts in special paper that prevents rust
and corrosion.

Inspect Parts

It is very important to inspect all parts carefully and
completely before the axle or carrier is assembled.
Check all parts for wear and replace damaged parts.
Replacement of damaged or worn parts will prevent
breakdown of assembly later.
