AUTOMATIC TRANSAXLE

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

1. Inspect the clutch operation by applying

compressed air as shown.

Air pressure

392 kPa {4.0 kgf/cm

2

, 57 psi} max.

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

(See 05–17–72 LOW AND REVERSE BRAKE
AND ONE-WAY CLUTCH INNER RACE
DISASSEMBLY/ASSEMBLY.)

Clutch clearance

1. Measure the low and reverse brake clearance.

(1) Set the dial gauge to the low and reverse brake.
(2) Set the measuring point of the dial gauge to

the low and reverse brake piston.

(3) Apply compressed air to the part indicated in

the figure and let the low and reverse brake
piston stroke three times.

Air pressure

98.1 kPa {1.0 kgf/cm

2

, 14 psi}

(4) Apply compressed air and operate the low

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

(5) Release the compressed air and read the dial

gauge when the low and reverse brake piston
is not operating.

(6) Calculate the low and reverse brake

clearance according to the following formula:
Step (4) value – Step (5) value = low and reverse brake 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:

Low and reverse brake clearance

2.20—2.50 mm {0.087—0.098 in}

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

Backlash

1. Measure the backlash of the side gear.

Backlash

Standard: 0.05—0.15 mm {0.002—0.005 in}
Maximum: 0.5 mm {0.020 in}

2. If not specified, replace the differential. (See 05–
