Disassembly Procedure

1.  Perform a simple inspection of the low clutch and high clutch using the following procedure:

(1)  Set the oil pump on the workbench as shown in the figure.
Note
•  Using the rubber plates, adjust the alignment surface of the oil pump with the transaxle case so that it is level.

A  :Rubber plate
(2)  Assemble the thrust needle bearing to the clutch component using the following procedure:
Note
•  Thrust needle bearing size: Outer diameter approx. 76.7 mm {3.02 in}
1)  To prevent the thrust needle bearing from dropping out, apply ATF (ATF FZ) to the thrust needle bearing.
2)  Assemble the thrust needle bearing.

(3)  Assemble the parts assembled together in Step (2) to the oil pump.

(4)  Blow compressed air into the oil passage shown in the figure and verify the operation condition of the low clutch.
Warning
•  Always wear protective eye wear when using the air compressor. Otherwise, ATF or dirt particles blown off by the air compressor could get into the eyes.
Caution
•  To prevent damage to parts, always use an air compressor which is adjusted to the indicated pressure.

Compressed air pressure
0.39—0.44 MPa {4.0—4.4 kgf/cm2, 57—63 psi}
•  If there is a malfunction, verify the cause and repair the applicable part after disassembly.
(5)  Blow compressed air into the oil passage shown in the figure and verify the operation condition of the high clutch.
Warning
•  Always wear protective eye wear when using the air compressor. Otherwise, ATF or dirt particles blown off by the air compressor could get into the eyes.
Caution
•  To prevent damage to parts, always use an air compressor which is adjusted to the indicated pressure.

9.  Remove the snap ring using the following procedure:

(1)  Install the SSTs.
Note
•  When installing the SST (49 G019 025) to the SST (49 G019 026), use the nuts included with the SST (49 G019 025), or M8×1.25 nuts.

(2)  Tighten the SST (49 G019 029) until there is no longer any spring force from the springs and retainer component applied to the snap ring.
Caution
•  If the SST (49 G019 029) is tightened with excessive force, surrounding parts could be damaged. Stop tightening if a gap appears between the snap ring and seal plate.
