Inspection After Removal

OIL PUMP

WARNING:
• To avoid the risk of injury to eyes and skin, when using caustic solutions, solvents, acids, or alkaline materials follow the manufacturer's recommendations for use and wear appropriate eye protection and protective clothing. Some of these materials are also flammable. To avoid risk of fire or burns, never smoke or allow sparks or flames (such as pilot lights, electrical switches, or welding equipment) in the work area. Avoid spilling onto a hot exhaust manifold which can cause a fire.
• Some solvents are flammable and toxic. Read the manufacturer's instructions before using.
• When using compressed air for cleaning, to avoid the risk of personal injury from flying debris and dirt:
  • Do not exceed 207 kPa (2.111 kg/cm ² , 30 psi).
  • Wear appropriate eye protection and protective clothing including gloves.
• Clean the oil pump with solvent.
• Dry with compressed air.
• Inspect the oil pump for damage and correct operation. If damage is present, replace the oil pump.
• Inspect the oil pump gears for chips, cracks, and excessive wear. If damage is present, replace the oil pump.
• Inspect the oil pump housing and rotor drive for damage and excessive wear.
• If the oil pump is damaged, the oil pump must be replaced.
  NOTE: The oil pump is serviced/replaced as an assembly. No internal parts are available for rebuild/replacement.

BLOCK STIFFENING PLATE

WARNING:
• To avoid the risk of injury to eyes and skin, when using caustic solutions, solvents, acids, or alkaline materials follow the manufacturer's recommendations for use and wear appropriate eye protection and protective clothing. Some of these materials are also flammable. To avoid risk of fire or burns, never smoke or allow sparks or flames (such as pilot lights, electrical switches, or welding equipment) in the work area. Avoid spilling onto a hot exhaust manifold which can cause a fire.
• Some solvents are flammable and toxic. Read the manufacturer's instructions before using.
• When using compressed air for cleaning, to avoid the risk of personal injury from flying debris and dirt:
  • Do not exceed 207 kPa (2.111 kg/cm ² , 30 psi).
  • Wear appropriate eye protection and protective clothing including gloves.
CAUTION: Do not allow solvents to enter the lubricating oil system. Solvents can reduce the ability of the lubricating oil to minimize component wear.
• Use solvent to clean the block stiffener plate cavity while the pump is removed.
• Dry with compressed air.
• Remove and inspect the oil check valve in the block stiffening plate for proper operation. Refer to Removal and Installation .
• Inspect the oil pressure regulator in the block stiffener plate. Refer to Removal and Installation .
• Inspect the oil pump bushing (1) in the block stiffening plate. If the bushing is worn or damaged, the block stiffening plate must be replaced. Refer to Removal and Installation .
