1. Clutch System
Condition Possible cause and testing Corrective action
1. Clutch slip-
pageIt is hard to perceive clutch slippage in the early stage, but pay attention to the following symptoms.
(a) Engine revs up when shifting.
(b) High speed driving is impossible; especially rapid acceleration impossible and vehicle speed does not increase in
proportion to an increase in engine speed.
(c) Power falls, particularly when ascending a slope, and there is a smell of burning of the clutch facing.
Method of testing: Put the vehicle in stationary condition with parking brake fully applied. Disengage the clutch and
shift the transmission gear into the first. Gradually allow the clutch to engage while gradually increasing the engine
speed. The clutch function is satisfactory if the engine stalls. However, the clutch is slipping if the vehicle does not
start off and the engine does not stall.
(a) No clutch pedal play Readjust.
(b) No release lever end play Readjust.
(c) Clutch facing smeared by oil Replace.
(d) Worn clutch facing Replace.
(e) Deteriorated diaphragm spring Replace.
(f ) Distorted pressure plate or flywheel Correct or replace.
(g) Defective release bearing holder Correct or replace.
(h) Defective pedal and cable system Correct or replace.
2. Clutch
drags.As a symptom of this trouble, a harsh scratching noise develops and control becomes quite difficult when shifting
gears. The symptom becomes more apparent when shifting into the first gear. However, because much trouble of the
this sort is due to defective synchronization mechanism, carry out the test as described after.
Method of testing: Refer to DIAGNOSTIC DIAGRAM on page after.
It may be judged as insufficient disengagement of clutch if any noise occurs during this test.
(a) Excessive clutch pedal play Readjust.
(b) Excessive clutch release lever play Readjust.
(c) Worn or rusty clutch disc hub spline Replace clutch disc.
(d) Excessive deflection of clutch disc facing Correct or replace.
(e) Seized crankshaft pilot needle bearing Replace.
(f ) Malfunction of pedal and cable system Correct or replace.
(g) Cracked clutch disc facing Replace.
(h) Sticked clutch disc (smeared by oil or water) Replace.
3. Clutch chat-
ters.Clutch chattering is an unpleasant vibration to the whole body when the vehicle is just started with clutch partially
engaged.
(a) Improper clutch cable routing Correct.
(b) Adhesion of oil on the facing Replace clutch disc.
(c) Weak or broken torsion spring Replace clutch disc.
(d) Defective facing contact or excessive disc Replace clutch disc defection.
(e) Warped pressure plate or flywheel Correct or replace.
(f ) Loose disc rivets Replace clutch disc.
(g) Loose engine mounting Retighten or replace mounting.
(h) Improper adjustment of pitching stopper Adjustment.
