Clutch Booster
INSPECTION
Hoses and connectors
+Check condition of vacuum hoses and connections.
+Check vacuum hoses and check valve for air tightness.
Vacuum hose check valve
1. Remove the vacuum hose.
2. Blow air through one end (booster side) of the vacuum hose
and make sure that air passage continuity exists.
3. Blow air through the other end (engine side) of the vacuum
hose and make sure that air passage continuity does not exist.
Check valve
1. Remove the vacuum hose.
2. Check the condition of the check valve using a handy vacuum
pump.

CLUTCH RELEASE MECHANISM
CL-11

INSPECTION
+Check release bearing to see that it rolls freely and is free from
noise, cracks, pitting or wear. Replace if necessary.
+Check release sleeve and withdrawal lever rubbing surface for
wear, rust or damage. Replace if necessary.
LUBRICATION
+Apply recommended grease to contact surface and rubbing
surface.
+Too much lubricant might damage clutch disc facing.
WATERPROOF
+Apply recommended sealant to contact surface of transmission
case dust cover and withdrawal lever, then install dust cover
clip.
Recommended sealant:
Nissan genuine part (KP115-00100) or equivalent.

Clutch Disc
INSPECTION
Check clutch disc for wear of facing.
Wear limit of facing surface to rivet head:
0.3 mm (0.012 in)
+Check clutch disc for backlash of spline and runout of facing.
Maximum backlash of spline (at outer edge of disc):
Model 240
1.0 mm (0.039 in)
Runout limit:
Model 240
0.7 mm (0.028 in)
Distance of runout check point (from hub center):
Model 240
115.0 mm (4.53 in)
+Check clutch disc for burns, discoloration or oil or grease leak-
age. Replace if necessary.
INSTALLATION
+Apply recommended grease to contact surface of spline por-
tion.
Too much lubricant might cause clutch disc facing damage.

Clutch Cover and Flywheel
INSPECTION
+Set Tool and check height and unevenness of diaphragm
spring.
Diaphragm spring height ``A'':
Model 240
37.5 - 39.5 mm (1.476 - 1.555 in)
+Check thrust rings for wear or damage by shaking cover
assembly up and down to listen for chattering noise, or lightly
hammering on rivets for a slightly cracked noise. Replace
clutch cover assembly if necessary.
+Check pressure plate and clutch disc contact surface for slight
burns or discoloration. Repair pressure plate with emery paper.
+Check pressure plate and clutch disc contact surface for defor-
mation or damage. Replace if necessary.
+Adjust unevenness of diaphragm spring with Tool.
Uneven limit:
0.7 mm (0.028 in)
+Check ¯ywheel and clutch disc contact surface for slight burns
or discoloration. Repair ¯ywheel with emery paper.
+Check ¯ywheel runout.
Maximum allowable runout:
Refer to EM section (``Inspection'', ``CYLINDER
BLOCK'').
