TEST OR INSPECTION
(2) Wash all parts of the muffler and wipe
dry. Wash element and blow dry with low
(3) Inspect element for excessive wear or
loss of capacity to retain dust and dirt.
Replace a defective element.
c. Reassemble the intake muffler as
(1) Install the T-stud (21), ferrule (20),
upper cover (19), plate (18),
separator (17), element (16), screen (15),
lower cover (14) and wing nut (13).
Tighten wing nut finger tight.
Step 2. Check V-belts for proper
adjustment. Also make a visual
securing motor to receiver. Move motor
inspection of belts and condition to
determine if the belts require
removal for cleaning and deglazing.
If deglazing appears necessary,
remove the lock belt guard.
Dry cleaning solvent P-D-680, used to clean parts is potentially dangerous to
personnel and property. Use in a well ventilated area as the fumes are dangerous
if inhaled. Do not use near open flame or excessive heat. Flash point of solvent is
100F. - 138F. (38 C. - 59C.).
b. Use a cloth dampened in dry cleaning
solvent P-D-680 to remove oil and dust
film. If the belts appear to have been
saturated, and the heat has glazed the
surfaces of the Vee's, proceed as follows:
c. Use a medium grade of grit sand paper
(not emery cloth) and rough up the surface
with strokes of uneven direction.
d. Wipe off all grit particles. When surfaces
have been deglazed, install the belts on
When installing new belts. never pry the belts over the pulley grooves.
e. To adjust the belts, move the motor
tension on the V-belts. Depress one of the
V-belts midway between the pulley and
flywheel; when the top lines up with the
bottom of the belt next to it under normal
thumb pressure the tension is correct.
