Troubleshooting
Reverse Gear Noise Reduction System
Whenever the clutch pedal is depressed to shift into reverse, the mainshaft continues to rotate because of its inertia.
The resulting speed difference between mainshaft and reverse idler gear produces gear noise.
The reverse gear noise reduction system employs a cam plate which was added to the reverse shift holder. When shifting
into reverse, the sth/reverse shjft piece, connected to the shift lever, rotates the cam plate. This causes the sth synchro set
to stop the rotating mainshaft. As there is no speed difference between mainshaft and reverse idler gear, there will be less
gear norse.
NOTE: This system is not a fully-synchronized gear noise reduction system.
Therefore, you may hear gear noise when
O you shift into reverse with the vehicle not yet completely stopped.
@ you shift quickly into reverse during fast idling.
-
Gear noise is oresent when shift-ing into reverce after the engineis started.
Test-drive the vehicle.
ls the gear noise present whenshifting into 5th gear?Beplace the 5th synchro hub and3leeve e3 a set,
Measure the clearance between5th shift fork and 5th synchrosleeve {see page 13'26).
ls the clearance 1.0 mm (0.04
in) or less?
Measure the MBS shift piece pin(see page 13-27).
ls ( 6.8 mm (0.27 in) or more?Replace the MBS shift piece.

Installation
Install the transmission assembly in the reverse order of
removal.
Before installing, check that the two dowel pins are
installed in the clutch housing.
When installing the starter cable, make sure that the
crimped side of the ring terminal is facing out (see
section 23).
Apply grease to the parts as shown, then install the
release fork and release bearing,
NOTE: Use only Super High Temp Urea Grease
(P/N 08798 - 9002).
