are dried by rotating with compressed air.
The parts, except the bearing cones, can be dried with
compressed air.
NOTE: Dry the parts immediately after the parts are
cleaned and washed.
Dry the parts with soft, clean paper or rags.
NOTE: Apply the fluid used in the brake housing to
the cleaned and the dried parts that are not damaged
and are to be assembled.

Ground and Polished Parts
WARNING
To prevent serious eye injury, always wear safe
eye protection when doing maintenance or ser-
vice.
If you use cleaning solvents, hot solution tanks,
or alkaline solutions incorrectly, serious per-
sonal injury can occur. To prevent serious
personal injury, follow the instructions sup-
plied by the manufacturer of these products.
Do NOT use gasoline to clean parts. Gasoline
can explode and cause serious personal injury.
CAUTION
Use only solvent cleaners to clean ground or
polished metal parts. Hot solution tanks or wa-
ter and alkaline solutions will damage these
parts. Isopropyl alcohol, kerosene, or diesel
fuel can be used for this purpose.
1. Use solvent cleaner to clean surfaces.
2. If necessary, remove gasket material from parts.
Parts With Rough Finish
NOTE: Do not clean friction discs. Wipe off each disc
with a clean rag before applying brake cooling fluid
to their surfaces during assembly.
Parts must remain in hot solution tanks until com-
pletely cleaned and heated.
1. Clean with cleaning solvent or in a hot solution
tank with a weak alkaline solution.
2. Remove parts from the hot solution and wash
them with water until the hot solution is re-
moved.
Wet Disc Brake and Axle Assembly
NOTE: Before the assembly is cleaned, close or put
a cover over all openings. Breathers or vents in the
axle assembly are some examples of openings.
1. Use steam to clean the outside of the wet disc
brake and axle assembly.
INSPECT
NOTE: Inspect all the parts before assembling the
wetdiscbrake. Checkallpartsforwearandre-
place the damaged parts. Replacing worn or dam-
aged parts prevents the failure of the assembly later.
