Engine Oil Pressure
1. Remove the engine oil pressure switch, and set an oil pressure
tester (Code No.: 07916-32032).
2. Start the engine. After warming up, measure the oil pressure of
both idling and rated speeds.
3. If the oil pressure is less than the allowable limit, check the
following.
• Engine oil insufficient
• Oil pump defective
• Oil strainer clogged
• Oil filter cartridge clogged
• Oil gallery clogged
• Excessive oil clearance
• Foreign matter in the relief valve
(When reassembling)
• After checking the engine oil pressure, tighten the engine oil
pressure switch to the specified torque.

Checking Fan Drive Belt Tension
CAUTION
• Be sure to stop the engine and remove the key before
checking belt tension.
1. Measure the deflection (A), depressing the belt halfway between
the fan drive pulley (1) and dynamo pulley (2) at specified force
98 N (10 kgf, 22 lbs).
2. If the measurement is not within the factory specifications, loosen
the dynamo mounting screws and relocate the dynamo to adjust.
