Malfunctions of Other Clutch Components
Malfunctions of Other Clutch Components
PROBLEM: Dicult to disengage gear/Slipping clutch.
SYMPTOM: Malfunction of cylinder assembly.
CAUSE: In case of CSC, Concentrated Slave Cylinder,
internal piston not traveling smoothly causes
system failure, and it may result in following
symptom;
Dicult to disengage gear:
1. Fixing or sticky movement causes short stroke
and results in dicult to disengage.
2. Leaking oil causes short stroke and results in
dicult to disengage:
Slipping clutch:
1. Oil on a friction facing due to leakage from
cylinder assembly causes slipping clutch.
2. In case of malfunction in regard to piston
return, it causes continuous semi-disengagement
and results in slipping clutch as well as facing
abnormal wear and burst by burnout.
SOLUTION: Always replace with new cylinder assembly.
Install cylinder assembly after ensuring smooth
movement.
PROBLEM: Notchy clutch pedal/Slipping clutch.
CAUSE: Abnormal wear on front cover, notchy wear.
Clutch release bearing carrier not travelling
smoothly on quill shaft/gear box nose cone slide.
SOLUTION: Apply appropriate grease. Renew worn out parts
or scratched parts.
PROBLEM: Clutch slipping, premature wear.
CAUSE: Slipping:
Not enough friction area causes less torque
transmittance and results in slipping under heavy
load due to reuse of worn ywheel.
Premature wear:
Reuse of worn ywheel is same condition as
worn clutch disc, and it results in premature wear.
If you resurface friction surface only, it causes
premature wear as well
SOLUTION: 1. Replace with new clutch.
2. Use ywheel which has the same dimension
as new, the height « between clutch cover
mounting surface and friction surface shown in
gure.
PROBLEM: Dicult to disengage gear/Noisy clutch.
CAUSE: Reuse of pilot bearing.
Noise:
Reuse of deteriorated pilot bearing may
cause abnormal noise from the bearing under
depressing clutch pedal condition.
Dicult to disengage gear:
Reuse of bearing which is not smooth movement
causes dicult to disengage gear, because
it transmits torque under disengagement
condition.
SOLUTION: Always replace with new pilot bearing when you
replace clutch.
PROBLEM: Dicult to engage gears. Noise when clutch is
engaged.
SYMPTOM: Damaged pilot busing.
CAUSE: Improper installation practices. Forcing the input
shaft/transmission on crank bushing engine
block.
SOLUTION: Align the transmission to the crank/engine block
during installation. Never force transmission to
engine.
Do not use bell housing bolts to force the
transmission on to the engine block.
Proper installation practices.
