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.


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.
