A front sump (1 ), rear sump (2), or center sump (3) lubricating oil pan option can be used depending on the application. The type and mounting of the lubricating oil suction tube will vary with the lubricating oil pan used.
Fill the lubricating oil pump with clean 15W-40 engine oil. Install the lubricating oil pump. Due to similarities in lubricating oil pump designs, always verify the replacement components are correct prior to installation. Using the sequence shown, torque the capscrews in the following steps: The back plate on the pump seats against the bottom of… Read More »
Measure the tip clearance. Measure the clearance of the gerotor drive/gerotor planetary to port plate. Measure the gear backlash.
Clean the lubricating oil pump with solvent. Dry with compressed air. With the pump removed use solvents to clean the cylinder block cavity. Dry with compressed air. Inspect the lubricating oil pump gears for chips, cracks, or excessive wear. If debris has been expected to have gone through the lubricating oil pump, the rear cover… Read More »
Remove the four mounting capscrews (1, 2, 3, and 4). Remove the lubricating oil pump from the bore in the cylinder block.
Use gauge, Part Number 3824564, and magnetic base, Part Number 3377399, to measure the lubricating oil pump driven gear backlash. If the backlash is out of specification, the lubricating oil pump must be replaced. If the adjoining gear moves during the measurement, the reading will be incorrect.
NOTE: Due to similariti es in lubricating oil pressure components design, always verify the replacement components are correct before installing. Install a new sealing a-ring on the threaded plug and lubricate with clean lubricating engine oil. Install the pressure regulator plunger, spring, and threaded plug. Tighten the plug. Torque Value: 80 N•m [ 59 ft-lb… Read More »
Thoroughly clean all components with clean solvent. Dry the parts with compressed air. NOTE: If the plunger bore requires cleaning, remove the housing so as not to flush debris into the engine. Refer to Procedure 007-003 in Section 7. Inspect the plunger bore. Polished areas on the plunger and bore are acceptable. Verify that the… Read More »
Remove the pressure regulator, valve plug, spring, and plunger. Service Tip: The plunger normally can be removed by inserting a finger into the plunger bore until snug and pulling up. If the plunger can not be removed in this manner, the plunger is probably stuck and will require removal of the housing.
• Disconnect the batteries. Refer to the OEM instructions. • Thoroughly clean the area around the pressure regulator plug with clean solvent to prevent debris from falling into the plunger bore when the plug is removed.
