Disassembly Procedure

1.  Perform a simple inspection of the 2-6 brake using the following procedure:

(1)  Blow compressed air into the oil passage shown in the figure and verify the operation condition of the 2-6 brake.
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.

2.  Perform a simple inspection of the R-3-5 brake using the following procedure:

(1)  Blow compressed air into the oil passage shown in the figure and verify the operation condition of the R-3-5 brake.
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.

3.  Remove the brake housing using the following procedure:

8 bolts
2
Brake housing

(1)  Loosen the bolts shown in the figure uniformly and remove them.
Caution
•  If the bolts are not loosened uniformly and removed, the brake housing will slant and parts could be damaged due to the spring force of the springs and retainer component in the brake housing.

4.  Remove the 2-6 brake piston from the brake housing using the following procedure:

(1)  Blow compressed air into the oil passage shown in the figure.
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.

(2)  Set the SST and part to the press as shown in the figure.
Caution
•  Using the rubber plates, adjust the alignment surface of the end cover with the transaxle case so that it is level. Otherwise the parts could tip over during the procedure and get damaged.

B  :Rubber plate
(3)  Press the SST down using a press until there is no longer any spring force from the springs and retainer component applied to the snap ring.
Caution
•  If the SST is pressed excessively by the press, surrounding parts could be damaged. Stop pressing the SST down using a press if a gap appears between the snap ring and retaining plate.
