The oil pump can be disassembled for inspection but not repaired. The oil pump is only serviced as an assembly. Individual parts are not available.
Replace the pump if the oil pickup strainer and tube are loose, cracked, or distorted. Also replace the pump if the housing is damaged or the pump gears are worn, chipped, or cracked. Check the pump shaft and pressure relief valve and spring. Replace the pump if the spring is collapsed or broken, the valve is damaged, the retaining pin is loose, or damaged, or the pump shaft is worn or damaged.
The oil pickup strainer can be cleaned with spray-type carb cleaner if necessary. However, replace the pump if heavy accumulations of oil sludge, grit, foreign material, or metal chips are present.
