Removal

NLCL0045

Remove manual transaxle from vehicle. Refer to MT-18,
“Removal”.

Move withdrawal lever enough to remove release bearing, and
remove release bearing from clutch lever.

Support clutch lever claws with an appropriate wood block,
align retaining pin with A in the figure, and drive out spring pin
using a pin punch.

Pull out withdrawal lever and remove clutch lever.

SCL733

Inspection

NLCL0046

Replace the release bearing if it is seized, damaged, faulty in
rotation direction, or has poor aligning function.

Replace the withdrawal lever if its contact surface is worn
abnormally.

Replace the clutch lever if its contact surface is worn abnor-
mally.

Replace the dust seal if it is deformed or cracked.

Installation

NLCL0047

CAUTION:

Be sure to apply grease to the clutch components.
Otherwise, abnormal noise, poor clutch disengagement,
or clutch damage may occur. Wipe the excess grease off
completely, because it may cause the clutch components
to slip and shudder.

Keep the clutch disc facing, pressure plate, and flywheel
free of oil and grease.

CL-17

YCL002

Clean old grease and abrasive materials off the grease
application area.

Apply approximately 1 mm (0.04 in)-thick clutch sleeve
grease evenly on the sliding part of the clutch lever and
the release bearing spring.

Apply just enough clutch sleeve grease to fill up the
release bearing inner groove.

Apply the clutch grease to the clutch disc and the input
shaft spline. Install the clutch disc to the input shaft,
remove the excess grease around the shaft, and remove
the clutch disc.

Lightly and evenly apply the clutch sleeve grease on the
sliding part of the release bearing, install the release
bearing, remove the excess grease around the bearing,
and remove the release bearing.

SCL822

Assemble clutch lever to clutch housing, and insert withdrawal
lever.

Support clutch lever claws with an appropriate wood block, and
install a new spring pin using a pin punch.

CAUTION:

Spring pin cannot be reused.

SCL736

Install release bearing spring to release bearing as shown in
the figure.

SCL823

Operate withdrawal lever manually, press clutch spring from
both sides, and install release bearing to clutch lever securely.

Make sure a click is heard when release bearing spring is
pressed from both sides.

SCL733

Inspection

NLCL0029

Replace the release bearing if it is seized, damaged, faulty in
rotation direction, or has poor aligning function.

Replace the withdrawal lever if its contact surface is worn
abnormally.

Replace the dust cover if it is deformed or cracked.

Installation

NLCL0030

Apply a coat of grease to parts as instructed in the following
cautions and notes before installation.

CAUTION:

Keep the clutch disc facing, pressure plate, and flywheel
free of oil and grease.

CLUTCH RELEASE MECHANISM

RS5F50A

Components

CL-20

Clean old grease and abrasive materials off the grease
application area.

SCL815

NOTE:

Equally apply a coat [approximately 1 mm (0.04 in) thick] of
clutch sleeve grease to withdrawal lever and holder spring
frictional surfaces.

Apply a coat of clutch sleeve grease to the grooves on contact
surfaces of the withdrawal lever ball pin and inner surface of
release bearing so that grease application, make sure that
grease is flush with grooves.

Equally apply a thin coat of clutch sleeve grease to release
bearing frictional surface. After grease application, install
release bearing. Wipe off excess grease forced out during
bearing installation. Remove release bearing.

Installation is in the reverse order of removal.
