Read all of manual to become thoroughly familiar with this vehicle. Pay particular attention to all Notes, Cautions and Warnings

REAR AXLE

The rear axle is provided with a lubricant level check plug
located on the driver side at the rear of the housing (Ref
Fig. 33 on page 18). Unless leakage is evident, an
annual lubricant check is sufficient.

Checking the Lubricant Level

Tool List

Qty. Required

Wrench, 13 mm ........................................................... 1

Funnel ......................................................................... 1

Clean the area around the check and fill plugs. Remove
the check plug.

The correct lubricant level is just below the bottom of the
threaded hole. If lubricant is to be added, remove the fill
plug and add lubricant (SAE 30 oil) using a funnel. Add
lubricant slowly until lubricant starts to seep from the
check plug hole. Install the check plug and the fill plug. In
the event that the lubricant is to be replaced, a drain plug
is provided at the bottom of the differential housing.
Capacity of axle is 40 oz. (1.2 liters).

STARTER/GENERATOR BELT TENSION

Tool List

Qty. Required

Belt tension gauge....................................................... 1

Wrench, 3/4"................................................................ 1

Wrench, 9/16".............................................................. 2

Ratchet, 3/8" drive ....................................................... 1

Socket, 3/4", 3/8" drive ................................................ 1

The starter/generator belt tension should be checked
after the first 15-20 hours of operation and set to 75 - 80
lbs. (34 - 36 kg).

A loose belt can cause audible vibration and
squeal.

Tighten a new starter/generator belt to 90 - 110 lbs. (41 -
50 kg) tension when a gauge is applied half way between
the two pulleys (Ref Fig. 34 on page 18).

Although not as accurate, the belt may be depressed
with a finger. A maximum deflection of 3/8" (1 cm) is
acceptable for a new belt.

Tighten an existing belt to 75 - 80 lbs. (34 - 36 kg) ten-
sion using the same technique. A maximum deflection of
1/2" (1.3 cm) is acceptable.

Adjusting the Belt

Using a 3/4" socket and open end wrench, loosen starter/
generator pivot bolt. While holding adjusting nut with a 9/
16" wrench, loosen jam nut with another 9/16" wrench.
Move adjusting nut up or down adjusting bolt until proper
belt tension is achieved. Hold adjusting nut in place and
tighten jam nut against it (Ref Fig. 36 on page 18).

Using a 3/4" socket and open end wrench, tighten the
starter/generator pivot bolt.
