2. Insert the spring seat and spring into the reverse lever shaft,
install the steel ball, and place a scraper so that it contacts
the steel ball.
3. With the edge of the control end against the scraper, when
the control end is pushed in the direction of the arrow in
the figure so that the ball goes into the shaft, the rod will
at the same time line up with the shift rod coupling hole in
the clutch housing.
4. Set each clutch hub sleeve to the neutral position, and tap
the shift rod from above so that the steel ball goes into the
center groove (of the 3 grooves in the control end).
5. Pull the ball part of the control end forward so that the steel
ball goes into the detent in the groove.
Crank lever assembly and crank lever shaft
Note
l Use a new O-ring for the crank lever shaft.
1. Fit the crank lever between the change arm and the con-
trol end, and connect the crank lever shaft to the crank lever.
2. Align the pin holes of the crank lever shaft and the clutch
housing, and insert the new pin. -’

same direction.
1. Install the shift rod end (1) and the shift rod (2), and tighten
the gate mounting bolt.
Reverse idler gear and reverse idler shaft
1. Install the reverse idler gear and the reverse idler shaft.
2. Attach the magnet to the clutch housing.
3. Align the end of the interlock sleeve with the control lever
(indicated by the arrow), and, at the same time, face the
reverse idler shaft screw hole in the direction shown in the
figure.

k:;;p{e method)
1. With the engine stopped, depress the pedal a few times.
2. With the pedal depressed, start the engine.
3. If immediately after the engine starts the pedal moves down
slightly, the unit is operating.
Step 2
1. Start the engine.
2. Stop the engine after it has run for
1 or 2 minutes.
3. Depress the pedal with the usual force.
4. If the first pedal stroke is long and becomes shorter with
subsequent strokes, the unit is operating.
5. If a problem is found, inspect for damage of the check valve
or vacuum hose and examine the installation. Repair if
necessary, and inspect it once again.
Step 3
1. Start the engine.
2. Depress the pedal with the usual force.
3. Stop the engine with the pedal held depressed.
4. Hold the pedal down for
about 30 seconds.
5. If the pedal height does not change, the unit is operating.
6. If there is a problem, check for damage to the check valve
or vacuum hose, and check the connection. Repair if neces-
sary and check once again.
If the nature of the problem is still not clear after the 3 steps
above, follow the more detailed check described in “Method-
using tester,” below.
(Method-using tester)
Connect a pressure gauge, vacuum gauge, and pedal depres-
sion force gauge as shown in the figure. After bleeding the
air from the pressure gauge, conduct the test as described
in the 3 steps below.
Note
l Use commercially available gauges and pedal
depression force gauge.
a) Checking for vacuum loss
Unloaded condition
1. Start the engine.
2. Stop the engine when the vacuum gauge reading reaches
500 mmHg (19.7 inHg).
3. Observe the vacuum gauge for 15 seconds. If the gauge
shows 475-500
mmHg (18.7-19.7 inHg), the unit is
operating.

1. Secure the mounting block in a vise.
Caution
l Use protective plates in the jaws of the vise.
2. Loosen the piston rod nut a few turns. Do not remove it.
Caution
l Do not remove the nut.
3. Compress the coil spring with the SST.
4. Remove the piston rod nut.

Inspection
Check for the following and replace the shock absorber if
necessary.
Secure a handle to the piston rod, and compress and expand
the shock piston at least three times. Verify that the operation-
al force does not change and that there is no unusual noise.
