MB990031(4) Position the special tool in the side bearing seat of the
gear carrier, and then select a drive pinion rear shim of athickness which corresponds to the gap between the
special tools.
NOTE
Clean the side bearing seat thoroughly. When position-
ing the special tool, be sure that the cut-out sections ofthe special tool are in the position shown in the
illustration, and also confirm that the special tool is in
close contact with the side bearing seat.
When selecting the drive pinion rear shims, keep the
number of shims to a minimum.
(5) Fit the selected drive pinion rear shim(s) to the drive
pinion, and press-fit the drive pinion rear bearing inner
race by using the special tool.
. ADJUSTMENT OF DRIVE PINION PRELOAD
Adjust the drive pinion turning torque by using the following
procedures:
(1) Fit the drive pinion front shim(s) between the drive
pinion spacer and the drive pinion front bearing inner
race.
(2) Tighten the companion flange to the specified torque byusing the special tools.
NOTEDo not install the oil seal.
(3) Measure the drive pinion turning torque (without the oil
seal) by using the special tools.
Standard value:

(4) If the drive pinion turning torque is not within the range
of the standard value, adjust the turning torque by
replacing the drive pinion front shim(s) or the drive
pinion spacer.
NOTEWhen selecting the drive pinion front shims, if the
number of shims is large, reduce the number of shims
to a minimum by selecting the drive pinion spacers.

SERVICE ADJUSTMENT PROCEDURES -
CHECKING COMPRESSION PRESSURENOSFFAI
(1) Before checking compression, ensure that engine oil, the
starter motor, and battery are all in good condition.
(2) Start the engine and wait until engine coolant temperature
has risen to
85-95°C (185-205°F).
(3) Stop the engine and pull the spark plug cables.
(4) Remove the spark plugs.
(5) Crank the engine to remove any foreign objects in the
cylinders.Caution
Cover the spark plug holes with shop towel, etc., in
order to keep expelled foreign objects from flying out,
and keep away from the holes. When measuring
compression with water, oil, or fuel having entered the
cylinder through a crack, etc., these will come flying
out of the spark plug hole hot and fast, so be sure to
take the proper precautions.
(6) Set the compression gauge to the spark plug hole.
(7) Holding the throttle valve full open, crank the engine and
measure compression.
Limit: Min. 920
kPa (130 psi) [250-400 rpm]
(8) Perform 6 and 7 above for all the cylinders, ensuring that
compression pressure differential for each of the cylinders
/Iis within the specified limit.
__Differential limit: Max. 100
kPa (14 psi)
(9) If a cylinder’s compression or pressure differential exceeds
the limit, add a small amount of oil through the spark plug
hole and repeat steps (6)-(8).
0If the addition of oil brings compression up, it is possiblethat there is poor contact between the piston ring and
cylinder wall.
@ If not compression does not come up, valve seizure,
poor valve seating, or a compression leak from the
gasket are all possible.
