NOTICE: Check the contact surface of the bushing in the direct clutch shaft. If any scratch or discoloration is found, replace the direct clutch sub-assembly with a new one. |
If the inside diameter is greater than the maximum, replace the forward clutch hub with a new one.
4. INSPECT 2ND BRAKE CLUTCH DISC
(a) Check if the sliding surface of the disc, plate and flange are worn or burnt.
If necessary, replace them.
NOTICE:
|
5. INSPECT 1ST AND REVERSE BRAKE CLUTCH DISC
(a) Check if the sliding surface of the disc, plate and flange are worn or burnt.
If necessary, replace them.
NOTICE:
|
6. INSPECT 1ST AND REVERSE BRAKE RETURN SPRING SUB-ASSEMBLY
(a) Using a vernier calipers, measure the free length of the spring together with the spring seat.
Standard free length: 17.61 mm (0.6933 in.) HINT: If the result is not as specified, replace the spring.
7. INSPECT UNDERDRIVE BRAKE RETURN SPRING SUB-ASSEMBLY

Standard free length: 13.24 mm (0.5213 in.) HINT: If the result is not as specified, replace the spring.
8. INSPECT PACK CLEARANCE OF 1ST AND REVERSE BRAKE
(a) Using vernier calipers, measure the distance between the disc surface and the contact surface of the 2nd brake cylinder and transaxle case (Dimension A).
(b) Select an appropriate flange so that the pack clearance will meet the specified value.
Pack clearance: 1.16 to 1.35 mm (0.0457 to 0.0531 in.)
HINT: Piston stroke = Dimension A - Flange thickness
Flange thickness: mm (in.)
(c) Install the flange.
9. INSPECT PACK CLEARANCE OF 2ND BRAKE
(a) Using a vernier calipers, measure the distance between the disc surface and snap ring surface (Dimension B).
(b) Select an appropriate flange so that the pack clearance will meet the specified value.
Pack clearance: 0.62 to 0.91 mm (0.0244 to 0.0358 in.)
HINT: Piston stroke = Dimension B - Flange thickness - Snap ring thickness 1.6 mm (0.063 in.)
Flange thickness: mm (in.)
(c) Install the flange.
9. INSPECT PACK CLEARANCE OF 2ND BRAKE
(a) Using a vernier calipers, measure the distance between the disc surface and snap ring surface (Dimension B).
(b) Select an appropriate flange so that the pack clearance will meet the specified value.
Pack clearance: 0.62 to 0.91 mm (0.0244 to 0.0358 in.)
HINT: Piston stroke = Dimension B - Flange thickness - Snap ring thickness 1.6 mm (0.063 in.)
Flange thickness: mm (in.)
10. INSPECT PACK CLEARANCE OF UNDERDRIVE BRAKE
(a) Using a dial indicator, measure the underdrive brake pack clearance while applying and releasing compressed air (392 kPa, 4.0 kgf/cm2, 57 psi).
Pack clearance: 1.81 to 2.20 mm (0.0713 to 0.0866 in.)
HINT: Select an appropriate flange from the table below so that it will meet the specified value.
Flange thickness: mm (in.)
(b) Temporarily remove the snap ring and attach it to the flange.
(c) Reinstall the snap ring.
11. INSPECT UNDERDRIVE 1-WAY CLUTCH ASSEMBLY
(a) Install the underdrive clutch assembly to the 1-way clutch.
(b) Rotate the underdrive 1-way clutch assembly to check the rotating direction for the lock or free operation.
HINT: If the result is not as specified, replace the underdrive 1-way clutch.
12. INSPECT INPUT SHAFT END PLAY
(a) Using a dial indicator, measure the input shaft end play.
End play: 0.262 to 1.244 mm (0.01 to 0.049 in.)
HINT: If the result is not as specified, replace the input shaft or thrust needle roller bearing.
Engine coolant
The coolant level is satisfactory if it is between the “FULL” and “LOW”
lines on the reservoir when the engine is cold.
Reservoir cap
“FULL” line
“LOW” line
If the level is on or below the
“LOW” line, add coolant up to the
“FULL” line.
