Pressure
NOTE: The engine must be warmed up to the
specified temperature for this test.
1. Connect the Arctic Cat Engine Tachometer (p/n
0644-275) to the engine.
2. Connect the Oil Pressure Gauge (p/n 0444-039)
to the oil filter drain plug (400/500), in the oil
pressure switch port (650 V-Twin), or to the
upper oil cooler hose at the engine (650 H1).
NOTE: Some oil seepage may occur when
installing the oil pressure gauge. Wipe up oil resi-
due with a cloth.
3. Start the engine and run at the specified RPM.

NOTE: If the oil pressure is lower than specified,
check for an oil leak, damaged oil seal, defective
oil pump, or restricted oil cooler.
NOTE: If the oil pressure is higher than speci-
fied, check for too heavy engine oil weight (see
