CLUTCH SYSTEM
PVT Drying
IMPORTANT: If operating the ATV through water, be
sure to check the PVT cover and other ATV
components for water ingestion. The ATV should be
checked immediately. Refer to Owner's Manual for
Safe Riding Tips.
To drain any water that may be trapped inside the PVT cover,
simply remove the PVT drain plug and O-ring located on the
bottom of the PVT cover and let the water drain out. The PVT
drain plug is shown below.
To further expel water in the PVT cover and to dry out the PVT
system, shift the transmission to neutral and rev engine slightly
to expel the moisture. This will also air-dry the belt and clutches.
Allow engine RPM to settle to idle speed, shift transmission to
lowest available range and test for belt slippage. Repeat as
needed. Operate ATV in lowest available range for a short
period of time until PVT system is dry.
