9.TROUBLESHOOTING
9-10
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)。
