(3) Remove pinion nut and washer.

11-6. Cleaning.
a.
Ground or Polished Surface Parts.
Exercise care to avoid skin rashes, fire
hazards, and inhalation of vapors when
using solvent-type cleaners.
Do not use gasoline. Do not clean these
parts in a hot solution tank or with water
and alkaline solutions, such as sodium
hydroxide, orthosilicates, or phosphates.
Do not steam clean assembled drive units
after they have been removed from the
housing. When this method of cleaning is
used, water is trapped in the cored pas-
sage of the castings and in the close
clearances between parts as welI as on the
parts. This can lead to corrosion (rust) of
critical parts of the assembly and the
possibility of circulating rust particles in
the lubricant. Premature failure of bear-
ings, gears and other parts can be caused
by this practice. Assembled drive units
cannot be properly cleaned by steam
cleaning, dipping or slushing. Complete
drive unit disassembly is a necessary
requisite to thorough cleaning.
(1)
parts having ground and polished surfaces, such as gears, bearings, shafts and collars, should
be cleaned in dry cleaning solvent (item 12, App B).
(2)
Clean all mating surfaces where fiber or liquid gasket material is used. It may be necessary
to use a scraper to completely remove gasket materials. Be careful, not to damage mating surfaces.
