F ENGINE TUNE-UP
23UOFX-046 Note
l When the parking brake is not applied, the idle
speed for ATX model (Canada) is approx. 800 rpm. Idle Speed
1. Perform “Preparation”. (Refer to page F-79.)
2. Apply parking brake.
3. Check that the idle speed is within specification.
Idle speed (Neutral or P range): 700-800 rpm
Caution
l Check the idle speed without the electric cooling
fan operating.
4. If not within the specification, adjust the idle by turning the
air adjusting screw.
5. Disconnect the SST.

Removal / Inspection / Installation
1. Remove in the order shown in the figure, referring to Removal Note.
2. Inspect all parts and repair or replace as necessary.
3. Install in the reverse order of removal, referring to
Installation Note.
4. After installation, bleed the brake system, adjust the parking brake lever stroke (Refer to Section P.) and
DRUM BRAKE TYPE
Preinspection
Wheel bearing play
1. Remove the wheel and tire.
2. Position a dial indicator against the brake drum. Push and
pull the rear brake assembly by hand in the axial direction
and measure the wheel bearing play.
3. If the bearing play exceeds specification, check and adjust
the locknut torque or replace the wheel bearing if necessary.
Maximum wheel bearing play: 0.05mm (0.002 in)
