WARNING
To prevent serious eye injury, always wear safe
eye protection when you perform vehicle
maintenance or service.

Clean Parts

Ground and Polished Parts
1. Use a cleaning solvent to clean ground or
polished parts or surfaces. Kerosene or diesel
fuel oil can be used for this purpose. DO NOT
USE GASOLINE.
WARNING
Solvent cleaners can be flammable, poisonous
and cause burns. Examples of solvent cleaners are
carbon tetrachloride, emulsion-type cleaners and
petroleum-based cleaners. To avoid serious
personal injury when you use solvent cleaners,
you must carefully follow the manufacturer's
product instructions and these procedures:
Wear safe eye protection.
Wear clothing that protects your skin.
Work in a well-ventilated area.
Do not use gasoline, or solvents that contain
gasoline. Gasoline can explode.
You must use hot solution tanks or alkaline
solutions correctly. Follow the manufacturer's
instructions carefully.
2. Use a tool with a flat blade, if required, to
remove sealant material from parts. Be careful
not to damage the polished or smooth
surfaces.
CAUTION
Do not use hot solution tanks or water and
alkaline solutions to clean ground or polished
parts. Damage to parts will result.
3. DO NOT clean ground or polished parts with
water or steam. Do not immerse ground or
polished parts in a hot solution tank or use
strong alkaline solutions for cleaning, or the
smooth sealing surface may be damaged.

Rough Parts
1. Clean rough parts with the same method as
cleaning ground and polished parts.
2. Rough parts can be cleaned in hot solution
tanks with a weak or diluted alkaline solution.
3. Parts must remain in hot solution tanks until
heated and completely cleaned.
WARNING
Solvent cleaners can be flammable, poisonous
and cause burns. Examples of solvent cleaners are
carbon tetrachloride, emulsion-type cleaners and
petroleum-based cleaners. To avoid serious
personal injury when you use solvent cleaners,
you must carefully follow the manufacturer's
product instructions and these procedures:
Wear safe eye protection.
Wear clothing that protects your skin.
Work in a well-ventilated area.
Do not use gasoline, or solvents that contain
gasoline. Gasoline can explode.
You must use hot solution tanks or alkaline
solutions correctly. Follow the manufacturer's
instructions carefully.
4. Parts must be washed with water until all
traces of the alkaline solution are removed.
Axle Assembly
1. A complete axle assembly can be steam
cleaned on the outside to remove dirt.
2. Before the axle is steam cleaned, close or
place a cover over all openings in the axle
assembly. Examples of openings are breathers
or vents in air chambers.
Breather
CAUTION
Clogged breathers can cause the internal pressure
of the unit to increase, causing oil to leak out of
the seals.
Clean the breather carefully (with compressed air).
Replace it if it is damaged.
