b. Points of Application. Follow the detailed lubrication instructions given beneath each lubrication point illustration
indicating procedures to be followed at each point. Apply the lubricant indicated on the lubrication order.
c. Cleaning. Use cleaning solvent or diesel fuel oil to clean or wash all parts. Use of gasoline for this purpose is
prohibited. Allow the cleaned parts to dry and wipe them with a clean absorbent cloth. Clean and dry all tools used in the
operation.
d. Clutch. Do not permit grease to be thrown and accumulate on the clutch.
e. Master Clutch Pilot Bearing. Insert the pipe nipple and grease fitting furnished with the tool kit into the tapped hole
on the clutch shaft and lubricate the master clutch pilot bearing according to the lubrication order.
f. Steering Roll Bearing. In lubricating the steering roll bearings, bear in mind that you must keep the space between
the axle and the tube full to insure delivery of grease to the center bearings.

Painting
a. Inspection. Inspect the housing, engine, and all painted surfaces for chipping, cracked, peeling, blistering, or
swollen paint. Never paint over loose or badly cracked paint. Inspect the metal surfaces for rust, corrosion, pitting, and
peeling paint.
b. Removing Rust. Use paint scrapers and chisels to remove as much scale, rust, peeled paint, and dirt as possible.
Brush the surface with a steel wire brush or with a power-driven wire brush to remove all paint and rust. Dust off loose
particles with a painter's duster. Areas around welds are particularly susceptible to rust and must be carefully cleaned and
primed.
c. Cleaning Bare Metal. Wash all grease and dirt from the surface to be painted with trisodium phosphate solution.
After application, rinse the surface with clean water and dry with clean cloths or with an air hose. If trisodium phosphate is
not available, paint thinners or solvents may be used. Sand the surface thoroughly, starting with No. 1 or No. 2 dry flint
paper and finishing with No. 000 flint paper. If wet-or-dry flint paper is available, start with No. 220 and finish with No.
600. When only one spot or portion of the surface is to be painted, sand down the surrounding old finish until a feather
edge is attained on the edge of the old finish. The old finish must slope smoothly away from the broken spot without any
distinct ridge or edge. Remove all dust with a painter's duster or air hose.
d. Masking. When painting with a spray gun, cover or mask all gages, identification plates, instruments, threaded
surfaces, lubrication fittings, and other parts which are not to be painted. Small areas or irregular shaped parts may be
covered with crepe-backed masking
