Forward Clutch Preinspection
Clutch operation

1. Set the forward clutch onto the oil pump.

Caution

• Applying compressed air to the assembled clutch pack for longer than 3 s at a time will damage 

the seal. 
Do not apply compressed air for more than the aforementioned time when testing the system.

2. Inspect the clutch operation by applying 

compressed air through the fluid passages 
shown.

Air pressure

392 kPa {4.0 kgf/cm

2

, 57 psi} max.

3. If not as specified, replace parts as necessary. 

(See 05–17–56 FORWARD CLUTCH 
DISASSEMBLY/ASSEMBLY.)

Clutch clearance

1. Measure the forward clutch clearance.

(1) Install the forward clutch in the oil pump, and set the dial gauge.
(2) Secure the forward clutch by lightly pressing 

down with a press, etc.

(3) Apply compressed air to the part indicated in 

the figure and let the forward clutch piston 
stroke three times.

Air pressure

392—441 kPa {4.0—4.5 kgf/cm

2

, 57—63 psi}

(4) Apply compressed air and operate the 

forward clutch piston. Read the value when 
the indicator of the dial gauge stops.

(5) Release the compressed air and read the dial 

gauge when the forward clutch piston is not 
operating.

(6) Calculate the forward clutch clearance 

according to the following formula:

Step (4) value – Step (5) value = Forward clutch clearance.

(7) Measure the clearances at four locations (90

° 

apart) by following the steps from (3) to (6). 
Verify that the average value is within the 
specification below.

Forward clutch clearance

1.50—1.80 mm {0.059—0.071 in}

2. If not as specified, replace parts as necessary. 

(See 05–17–56 FORWARD CLUTCH 
DISASSEMBLY/ASSEMBLY.)

Clutch Component Preinspection
Clutch operation

1. Set the clutch component onto the end cover.

Caution

• Applying compressed air to the assembled clutch pack for longer than 3 s at a time will damage 

the seal.
Do not apply compressed air for more than the aforementioned time when testing the system.

2. Inspect the clutch operation by applying 

compressed air as shown.

Air Pressure

392 kPa {4.0 kgf/cm

2

, 57 psi} max.

3. If not as specified, replace parts as necessary. 

(See 05–17–60 CLUTCH COMPONENT 
DISASSEMBLY/ASSEMBLY.)

Reverse clutch clearance

1. Measure the reverse clutch clearance.

(1) Install the reverse clutch into the end cover, and set the dial gauge.
(2) Secure the reverse clutch by lightly pressing 

down with a press, etc.

(3) Apply compressed air to the part indicated in 

the figure and let the reverse clutch piston 
stroke three times.

Air Pressure

392—441 kPa {4.0—4.5 kgf/cm

2

, 57—63 psi} 

(4) Apply compressed air and operate the 

reverse clutch piston. Read the value when 
the indicator of the dial gauge stops.

(5) Release the compressed air and read the dial 

gauge when the reverse clutch piston is not 
operating.

(6) Calculate the reverse clutch clearance 

according to the following formula: Step (4) value – Step (5) value = Reverse clutch clearance.

(7) Measure the clearances at four locations (90

° 

apart) by following the steps from (3) to (6). 
Verify that the average value is within the 
specification below.

Reverse clutch clearance

1.00—1.30 mm {0.039—0.051 in}

2. If not as specified, replace parts as necessary. 

(See 05–17–60 CLUTCH COMPONENT 
DISASSEMBLY/ASSEMBLY.)

3-4 clutch clearance

1. Measure the 3-4 clutch clearance.

(1) Install the 3-4 clutch in the end cover and set the dial gauge.
(2) Secure the 3-4 clutch by lightly pressing down 

with a press, etc.

(3) Apply compressed air to the part indicated in 

the figure and let the 3-4 clutch piston stroke 
three times.

Air pressure

392—441 kPa {4.0—4.5 kgf/cm

2

, 57—63 psi}

(4) Apply compressed air and operate the 3-4 

clutch piston. Read the value when the 
indicator of the dial gauge stops.

(5) Release the compressed air and read the dial 

gauge when the 3-4 clutch piston is not 
operating.

(6) Calculate the 3-4 clutch clearance according 

to the following formula:
Step (4) value – Step (5) value = 3-4 clutch clearance.
