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)
