Rear Differential AssemblY
Troubleshooting
Most problems in the unit are to be diagnosed by identifying noises from the gears or bear'ngs'
care should be taken during diagnosis not to confuse differential noises with those from other drivetra'n components'

Inspection and Adjustment
Pump Belt
When using a new belt. first adjust the deflection or ten-
sion to the values for the new belt, then readjust the
deflection or tension to the values for the used belt after
running engine for five minutes.
Inspection
Note these items during inspection:
a lf there are cracks or any damage evident on the belt,
replace it with a new one.
. Follow the manufacturer's instructions lor the tension
gauge.
'1. Remove the P/S reservoir from the bracket, and set
it aside.
2. Attach the belt tension gauge to the belt with the
gauge face toward the engine, and measure the ten-
sion of the belt.
Remove the belt tension gauge carefully to avoid
hitting the gauge reset lever.
Tension:
Used Belt: 390 - 540 N {40 - 55 kgf, 88 - 121 lbf)
New Belt: 7,[0 - 840 N (75 - 90 kgf, 165 - 198 lbf)
CRANKSHAFT PULLEY
17-14
Measurement without Belt Tension Gauge:
Apply a force ot 98 N (10 kgf,22 lbt) and measure the
deflection between the power steering pump and the
crankshaft oullevs.
Deflection:
Used Belt: 11.0 - 1i1.5 mm {0.'(l - 0.57 in)
New Belt: 7.5 - 10.0 mm {0.30 - 0.39 in)

Adjust the belt tension by moving the power steer-
ing pump with a 1/2" drive breaker bar to obtain theproper belt tension, then retighten the mounting
bolt and lock bolt.
Start the engine and turn the steering wheel from
lock-to-lock several times, then stop the engine and
recheck the deflection of the belt.
