The following chart is provided to help diagnose the probable source of troubles. It should be used as a
guideline. Some causes or corrections may not apply to a specific model.
TRANSMISSION
SYMPTOM THE SNOWMOBILE ACCELERATES SLOWLY, ESPECIALLY FROM A STANDING START.
CONDITION NORMAL USE
1. Check drive belt condition.
a. Belt is too narrow (drive belt engagement is higher in drive pulley).
Replace belt if width is less than specified in DRIVE BELT.
2. Check distance between pulleys and/or drive belt deflection.
a. Distance is too small between pulleys or deflection is too high (drive belt engagement is higher in drive
pulley).
Adjust distance between pulleys and/or drive belt height according to specifications (refer to PULLEY
DISTANCE AND ALIGNMENT and DRIVE BELT).
3. Check if driven pulley sliding half slides freely.
a. Jammed sliding half.
Replace.
4. Check spring tension of driven pulley sliding half.
a. Sliding half rotation is accelerated when spring tension is too weak.
Adjust according to specifications (refer to TECHNICAL DATA).
5. Refer to VIBRATIONS ORIGINATING FROM DRIVE PULLEY and VIBRATIONS ORIGINATING FROM
DRIVEN PULLEY and check items listed.
TEST/INSPECTION
6. Check drive pulley spring tension.
