Maintenance PVT SYSTEM
Belt Deflection Inspection
Excessive belt deflection is when the belt is too long or the center distance is too shortThe initial starting ratio will be too high, resulting in performance lossThis is due to the belt rising too high in the drive clutch sheaves upon engagement (A)Insufficient belt deflection (B) is when the belt is too short or the center distance is too longThe initial starting ratio will be too lowIn addition, the machine may creep when the engine idles, causing damage to the internal face of the drive belt4The measurement should be 1-14" (3.2cm)
= In mmBelt Deflection: 1.25" (3.2cm) 5If the measurement is not correct, adjust driven clutch
TeamP2 Deflection Adjustment CAUTION
The driven clutch can be damaged if the clutch is in reverse drive1Verify the drive system is in forward drive2While holding the set screw with an Allen wrench, loosen the jam nut3Turn the set screw clockwise while holding the jam nut stationary to increase the distance between the clutch sheaves (increase belt deflection)4Turn the set screw counter-clockwise while holding the jam nut stationary to decrease the distance between the clutch sheaves (decrease belt deflection)5Secure the jam nut while holding the set screw stationary6Raise the rear of the snowmobile using track stand to allow the track to spin7Start the engine and apply enough throttle to spin the track8Turn off then engine, and repeat belt deflection inspection
