4WD Piston
1. Press the pressure plate (4) to press down the 4WD piston (11),
using jig (refer to “4. SPECIAL TOOLS” at “NG. GENERAL”
section), and remove the internal circlip (3).
2. Remove the discs (5), steel plates (6), (7) and pressure plates
(4).
NOTE
Q
• 24 springs (outer) for 4WD piston.
• 15 springs (inner) for 4WD piston.
• 5 discs and 5 steel plates for 4WD clutch side.
(When reassembling)
• Apply transmission fluid to D-ring (12) and (13), then install the
4WD piston (9) with springs (11) and (12).
• Install the clutch discs (5) and steel plate (6), (7) mutually.
• Apply enough transmission fluid to the discs (5).
• Do not confuse the two types of steel plates.
The steel plate with plug rubbers (6) and without rubbers (7).
• Two steel plates match the position of rubber (8) from the piston
side, and one remaining steel plate is not matched.
• Do not confuse the pressure plates (4) and steel plate (7). The
pressure plate (4) is thicker than the steel plate.
• When installing the internal circlip (3) to the clutch case (1), press
the pressure plate (4) using a jig and align its split portion to the
notched portion of clutch case (1) as shown in photo.
• When installing the internal circlip (3), temporary align the spline
and teeth of clutch discs using the 35T gear.
