one-way clutch.
Spring sleeve(s) inside one-way clutch is (are) worn out. Replace both sleeves and springs
and lubricate inside of one-way clutch.
Spring(s) inside one-way clutch is (are) worn out. Replace both pins and springs and
lubricate inside of one-way clutch.
Symptom: DRIVE PULLEY NOISE WHEN ACCELERATING/DECELERATING
1.
Check if belt runs in dry condition.
Drive pulley area is wet/contaminated due to water/dirt intrusion. Clean driven pulley area
and/or drain water out of CVT cover.
2.
Check drive/driven pulley screw for torque.
Loose screw on drive pulley. Retighten screw with recommended torque.
3.
Check cam and driven pulley fixed sheave for wear.
Cam and/or drive pulley fixed sheave out of wear limit and/or damaged. Replace
damaged part(s).
4.
Check torque gear fixed in driven pulley sliding sheave for wear.
Torque gear out of wear limit and/or damaged. Replace torque gear).
5.
Check for foreign particles in CVT area (stones, dirt, etc.).
Small particles damaged belt and/or pulley surface(s). clean system and replace damaged
parts.
Symptom: VIBRATIONS ORIGINATING FROM DRIVE PULLEY
1.
Check tightening torque of drive pulley screw.
Moving sliding sheave. Retighten screw.
2.
Check fixed sheave bushings.
Excessive gap between bushings and fixed sheave shaft, thus restraining sliding sheave
movements. Replace fixed sheave assembly.
3.
Check if slider shoes are present and/or placed in correct position.
Slider shoe(s) is (are) missing and/or damaged. Replace all slider shoes at the same time
(slider shoes kit).
Symptom: VIBRATIONS ORIGINATING FROM DRIVEN PULLEY
1.
Check fixed and sliding sheave bushings on driven pulley.
Excessive gap between bushings and CVT shaft, thus restraining sliding sheave
movements. Replace fixed and/or sliding sheave of driven pulley, polish CVT shaft area
with fine emery cloth and wipe clean with a cloth.
Symptom: PULLEYS DO NOT DOWN/UP SHIFT PROPERLY.
1.
Check drive pulley bushings (cleanliness, wear, etc.)
Check items 1 and 2 of UNUSUAL ACCELERATION BEHAVIOR.
Bushings stick to fixed sheave pulley shaft. Clean or replace.
Spring seat sticks to sliding sheave pulley bushing. Clean system and/or replace sliding
sheave pulley.
One-way clutch does not operate properly. Clean system and/or replace damaged part(s).
2.
Check driven pulley spring tension.
Driven pulley spring tension is too weak or broken. Replace.
Driven pulley cam is worn or damaged. Replace.
Symptom: BELT GLAZED EXCESSIVELY OR HAVING BAKED APPEARANCE
1.
Check if CVT air intake and/or outlet is clogged.
CVT area heats up due to contamination. Clean air intake and/or outlet from
contamination.
Fans located on drive pulley is worn or damaged. Replace.
2.
Check if pulley sheaves are clean.
Oil on pulley surfaces. Clean pulley sheaves and replace belt.
Water intrusion in CVT area. Find root cause and repair. Drain water and replace belt.
Symptom: BELT WORN EXCESSIVELY IN TOP WIDTH.
1.
Check drive belt width.
Considerable wear. Replace belt if narrower than specified (refer to CONTINUOUSLY
VARIABLE TRANSMISSION (CVT) OR TECHNICAL SPECIFICATIONS)
。
2.
Check driver belt identification number.
Wrong type of belt. Replace belt with an appropriate drive belt.
3.
Check for localized belt wear caused by belt slippage.
Localized wear. Replace belt.
Symptom: BELT DISINTEGRATION.
1.
Check drive belt lifetime is exceeded..
Clean CVT system and rebuild with a new drive belt.
