01–01 Engine-Support

Fasteners Check

Check the rear engine-support fasteners (

Fig. 1

, Ref.

4) for tightness. Tighten the 3/4-inch fasteners 215 to
265 lbf·ft (292 to 359 N·m).

Check the front engine-support fasteners for tight-
ness. Tighten the 5/8-inch fasteners 125 lbf·ft (170
N·m).

NOTE: With Allison automatic transmissions, it
is necessary to remove the four fasteners hold-
ing the transmission oil cooler. Lower the cooler
out of the way to provide access to the front
engine mount.

NOTE: At engine overhaul, and whenever the
engine has been removed, inspect the lower
and upper isolators (

Fig. 1

, Refs. 1 and 6), and

replace them if they are worn. See Group 01 of
the

Cargo Workshop Manual for procedures.

01–02 Engine Drive Belt

Inspection

Worn or loose drive belts may cause premature
bearing failure or engine overheating. Excessive ten-
sion, or too little tension on the belt may result in ex-
cessive and premature belt wear. Poly-V belts, or
serpentine belts are retrained by a belt tensioner that
requires no tension adjustment. Replace the engine
drive belt if any conditions described in the visual
description are found. V-belts are installed as indi-
vidual belts, and as matched sets. When replacing a
matched set of belts, always replace both belts at the
same time. Matched belts must be from the same
manufacturer. To inspect a belt, gently twist the belt
to view the belt sidewalls and bottom. Visually in-
spect all belts for the following conditions, then per-
form the belt tension inspection:

Visual Inspection

Inspect the belt for glazing. See

Fig 2

, Ref. A.

Glazing is represented by shiny sidewalls, and is
caused by friction created when a loose belt slips
in the pulleys. It can also be caused by oil or
grease contamination on the pulleys.

Check the belt for ply separation. See

Fig. 2

, Ref

B. Oil, grease, or belt dressing can cause the
belt to fall apart in layers. Repair any oil or cool-
ant leaks that are affecting the belts before re-
placing the drive belts. Do not use belt dressing
on any belt.

Check the belt for a jagged or streaked sidewall.
See

Fig. 2

, Ref C. Jagged or streaked sidewalls

are the result of foreign objects, such as sand or
gravel in the pulley, or a rough pulley surface.

Check for tensile breaks; breaks in the cord
body. See

Fig. 2

, Ref D. Cuts in a belt are usu-

ally caused by foreign objects in the pulley, or by
prying or forcing the belt during removal or instal-
lation.

Check for uneven ribs on serpentine (poly-V)
belts. See

Fig. 2

, Ref E. Foreign objects in the

pulley will erode the undercord ribs, causing the
belt to lose its gripping power.
