DOUBLE-CONE SYNCHRONIZER NFMT0004S0101
Double-cone synchronizer is adopted for 1st and 2nd gears to
reduce operating force of the shift lever.
SCIA0750E
REVERSE GEAR NOISE PREVENTION FUNCTION
(SYNCHRONIZING METHOD) NFMT0004S0102
The gear can be matched smoothly in a structure by setting syn-
chronizer hub, coupling sleeve, baulk ring and insert spring to
reverse gear, and letting gear be synchronized.

2. Remove driveshaft. Refer to AX-10, "Drive Shaft".
3. Remove differential oil seals. MA
CAUTION:
Be careful not to damage the case surface when removing the
oil seal. EM
SCIA0824E LC
4. Using a drift (special service tool), drive the oil seal straight
until it protrudes from the case end equal to dimension A
shown in the figure. EC
Dimension "A":
Within 0.5 mm (0.020 in) of flush with the case. FE
Drift to be used:
