Clutch Drum And Input Shaft Assembly Inspection

Replace all discs if one of the following problems is present: 1) a disc, plate or flange is worn or burnt, 2) the lining of a disc is peeled off or discolored, or 3) grooves or printed numbers have even a little bit of damage.

NOTICE:

Before assembling new discs, soak them in ATF for at least 15 minutes.

Using a dial indicator, measure the inside diameter of the reverse clutch hub bushing.

Standard inside diameter:

35.812 to 35.837 mm (1.4099 to 1.4109 in.)

Maximum inside diameter:

35.887 mm (1.4129 in.)

1. If the inside diameter is greater than the maximum, replace the reverse clutch hub.
   

Using a dial indicator, measure the inside diameter of the forward clutch hub bushing.

Standard inside diameter:

26.037 to 26. 062 mm (1.0251 to 1.0261 in.)

Maximum inside diameter:

26.112 mm (1.028 in.)

1. If the inside diameter is greater than the maximum, replace the forward clutch hub.
   

Replace all discs if one of the following problems is present: 1) a disc, plate or flange is worn or burnt, 2) the lining of a disc is peeled off or discolored, or 3) grooves or printed numbers have even a little bit of damage.

NOTICE:

Before assembling new discs, soak them in ATF for at least 15 minutes.

Using a vernier caliper, measure the free length of the spring together with the spring seat.

Standard free length:

26.74 mm (1.053 in.)

Replace all discs if one of the following problems is present: 1) a disc, plate or flange is worn or burnt, 2) the lining of a disc is peeled off or discolored, or 3) grooves or printed numbers have even a little bit of damage.

NOTICE:

Before assembling new discs, soak them in ATF for at least 15 minutes.

Using a vernier caliper, measure the free length of the spring together with the spring seat.

Standard free length:

21.04 mm (0.828 in.)

Using a vernier caliper, measure the free length of the spring together with the spring seat.

Standard free length:

19.51 mm (0.768 in.)

Using a dial gauge, measure the moving distance (distance A) of the clutch flange at both ends across a diameter while blowing air from the oil hole as shown in the illustration, and calculate the average.

Standard pack clearance:

0.5 to 0.8 mm (0.020 to 0.031 in.)

NOTICE:

When measuring the moving distance, install a standard flange (thickness: 3.4 mm (0.031 in.)) to the position of the shaded area in the illustration.

HINT:

Flange moving distance A = 0.26 to 1.14 mm (0.010 to 0.045 in.)

Pack clearance = Flange moving distance A - 0.05 mm (0.002 in.)

If the pack clearance is not within the standard, select and install a clutch flange that makes the pack clearance within the standard.

Standard flange thickness:

No.	Thickness	No.	Thickness
0	3.0 mm (0.118 in.)	5	3.5 mm (0.138 in.)
1	3.1 mm (0.122 in.)	6	3.6 mm (0.142 in.)
2	3.2 mm (0.126 in.)	7	3.7 mm (0.146 in.)
3	3.3 mm (0.130 in.)	8	3.8 mm (0.150 in.)
4	3.4 mm (0.134 in.)	-	-

Using a dial gauge, measure the reverse clutch piston stroke (distance A) and the moving distance (distance B) of the reverse flange at both ends across a diameter while blowing air (392 kPa, 4 kgf/cm², 57 psi) from the oil hole as shown in the illustration, and calculate the average.

Standard pack clearance:

0.5 to 0.8 mm (0.020 to 0.031 in.)

NOTICE:

When measuring the moving distance, install a standard flange (thickness: 3.3 mm (0.130 in.)) to the position of the shaded area in the illustration.

HINT:

Piston stroke A = 1.05 to 2.15 mm (0.041 to 0.085 in.)

Flange moving distance B = 0.72 to 1.08 mm (0.029 to 0.043 in.)

Pack clearance = Piston stroke A - Flange moving distance B - 0.06 mm (0.002 in.)

If the pack clearance is not within the standard, select and install a clutch flange that makes the pack clearance within the standard.

Standard flange thickness:

No.	Thickness	No.	Thickness
0	2.8 mm (0.110 in.)	6	3.4 mm (0.134 in.)
1	2.9 mm (0.114 in.)	7	3.5 mm (0.138 in.)
2	3.0 mm (0.118 in.)	8	3.6 mm (0.142 in.)
3	3.1 mm (0.122 in.)	9	3.7 mm (0.146 in.)
4	3.2 mm (0.126 in.)	A	3.8 mm (0.150 in.)
5	3.3 mm (0.130 in.)	-	-

Using a dial gauge, measure the moving distance (distance A) of the clutch flange at both ends across a diameter while blowing air from the oil hole as shown in the illustration, and calculate the average.

Standard pack clearance:

0.6 to 0.9 mm (0.024 to 0.354 in.)

NOTICE:

When measuring the moving distance, install a standard flange (thickness: 3.4 mm (0.031 in.)) to the position of the shaded area in the illustration.

HINT:

Flange moving distance A = 0.26 to 1.36 mm (0.010 to 0.054 in.)

Pack clearance = Flange moving distance A to 0.01 mm (0.0003 in.)

If the pack clearance is not within the standard, select and install a clutch flange that makes the pack clearance within the standard.

Standard flange thickness:

No.	Thickness	No.	Thickness
0	3.0 mm (0.118 in.)	6	3.6 mm (0.142 in.)
1	3.1 mm (0.122 in.)	7	3.7 mm (0.146 in.)
