Section 02 TROUBLESHOOTING
Subsection 01 (TECHNICAL GUIDELINES)
Symptom:
DRIVE PULLEY NOISE WHEN ACCELERATING/DECELERATING
(cont’d)
2.
Check if belt runs in dry conditions.
-
Drive pulley area is wet/contaminated due to water/dirt intrusion. Clean driven pulley area and/or
drain water out of CVT cover.
3.
Check drive/driven pulley screw torque.
-
Loose screw on drive and/or driven pulley. Retighten screw with recommended torque.
4.
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).
5.
Check torque gear in driven pulley sliding sheave for wear.
-
Torque gear out of wear limit and/or damaged. Replace torque gear (refer to
CONTINUOUSLY
VARIABLE TRANSMISSION (CVT)
).
6.
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
(refer to
CONTINUOUSLY VARIABLE TRANSMISSION (CVT)
).
Symptom:
VIBRATIONS ORIGINATING FROM DRIVE PULLEY
1.
Check 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 move-
ments. Replace fixed sheave assembly.
3.
Check starter ring gear condition.
-
Starter ring gear loosened. Retighten ring gear and/or mount it in original position (balanced
system).
4.
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 DOWNSHIFT OR UPSHIFT PROPERLY
1.
Check drive pulley bushings (cleanliness, wear, etc.).
-
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 and/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.
-
Fins of drive pulley fixed sheave (underneath ring gear) are clogged. Clean from contamination.
