INSTALLATION
lApply recommended grease to contact surface of spline por-
tion.
Too much lubricant might cause clutch disc facing damage.
Clutch Cover
INSPECTION
lAdjust unevenness of diaphragm spring with Tool.
Uneven limit:
250 0.5 mm (0.020 in)
240 0.5 mm (0.020 in) Except TD25 engine
0.7 mm (0.028 in) TD25 engine
lSet Tool and check height and unevenness of diaphragm
spring.
Set 0.2 mm (0.008 in) feeler gauges on distance pieces
(ST20050100) when checking 240 or 250.
Diaphragm spring height ``A'':
240 37.5 - 39.5 mm (1.476 - 1.555 in)
250 37.0 - 39.0 mm (1.457 - 1.535 in)
lCheck 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.
lCheck pressure plate and clutch disc contact surface for
slight burns or discoloration. Repair pressure plate with
emery paper.
lCheck pressure plate and clutch disc contact surface for
deformation or damage. Replace if necessary.
INSTALLATION
lInsert Tool into clutch disc hub while installing clutch cover
and disc.
lBe careful not to allow grease to contaminate clutch facing.
lTighten bolts in numerical order, in two steps.
First step:
:10-20Nzm (1.0 - 2.0 kg-m,7-14ft-lb)
Final step:
:22-29Nzm (2.2 - 3.0 kg-m, 16 - 22 ft-lb)
