INSTALLATION
To install, follow the removal steps in the reverse order, noting
the following points;
Adjustment of select lever and control rod
1) Place the vehicle on a level surface.
NOTE:
If the vehicle is not on a level surface, the shift select cable
set position will vary with the movement of the engine. To
prevent possible misadjustment of the cable, the vehicle
must be placed on a level surface.
2) Install the shift control rod (1) to the transfmission select
lever (2), and then place the lever in the "N" position.
3) Set select lever in the "N" position.
4) Push select lever forward and secure it (using a rubber
band (3), etc.) so that pin comes into contact with the wall
of detent plate.
5) Install the shift control rod (1) to the selector lever arm (4).
NOTE:
Do not apply to threaded portions.
6) After adjustment, operate select lever on a trial basis to
makes sure of its smooth operation and no abnormal
indication in each position.
Adjustment of shift lock cable
1) Set ignition key in "LOCK" position and selector lever in "P"
position.
2) Adjust cable screw cap on selector lever side to provide a
gap (slack for cable) of 1–2mm between rod on steering
lock side and stopper.
Adjust cap as follows:
a. Pull screw cap (1) in arrow direction to put off slack of
inner cable.
b. With cable kept as (a), adjust gap between nut (2) and
bracket to 5mm (0.2in).
c. Lock inner cable by tur ning nut (3) while holding nut (2) in
place.
NOTE:
Clean the rod threads and do not apply oil to the threaded
portions.Nꞏm(kgꞏm / lbꞏft)

Check tip clearance of both gears
Measure between the gear teeth and the cresent-shaped
par t of the pump body.
If the tip clearance is greater than the maximum, replace
the drive gear, driven gear or pump body.
Check body clearance of driven gear
Push the driven gear to one side of the body.
Use a feeler gauge, measure the clearance.
If the body clearance is greater than the maximum, replace
the drive gear, driven gear or pump body.
Check side clearance of both gears
Using a steel straightedge and a feeler gauge, measure the
side clearance of both gears.
If the side clearance is greater than the maximum, replace
the drive gear, driven gear or pump body.
Check oil seal
Check for wear, damage or cracks.
If necessary, replace oil seal.
Pry off the oil seal with a screwdriver.mm (in.)
