Engine Oil Relief Valve
Removal Procedure
Remove the engine oil pan. Keep all parts clean from contaminants. Contaminants may cause rapid wear and shortened component life.
Use an allen wrench to loosen the cap (1). Carefully remove the cap (1) from the housing of the engine oil pump (4).
Engine oil relief valve
1 � cap, 2 � spring, 3 � plunger, 4 - engine oil pump
The spring force will be released when the cap is removed.
Remove the spring (2) from the bore for the relief valve in the housing of the engine oil pump (4). Use long nose pliers to remove the plunger (3) from the bore for the relief valve in the housing of the engine oil pump (4).
Installation Procedure
Ensure that all components are clean and free from wear or damage. If necessary, replace any components that are worn or damaged. If the bore for the relief valve in the housing of the engine oil pump (4) is worn or damaged, the complete assembly of the engine oil pump must be replaced.
Lubricate the plunger (3) with clean engine oil. Use long nose pliers to install the plunger (3) and the spring (2) into the bore for the relief valve in the housing of the engine oil pump (4).
The plunger must slide freely in the bore for the relief valve.
Apply Tooling to the threads of the cap (1). Use an allen wrench to install the cap (1) to the engine oil pump (4). Tighten the cap to a torque of 21 N�m (15.5 lb ft).
inside the plunger and the cap. Ensure that Tooling (A) does not contaminate the bore for the relief valve in the housing of the engine oil pump.
Install the engine oil pan.
Engine Oil Pump
Removal Procedure
Remove:
- the engine oil pan. If the suction pipe has a support bracket, remove the support bracket. Note the position and orientation of the components for the support bracket.
1 - setscrews, 2 - suction pipe, 3 � setscrews, 4 - engine oil pump, 5 - pressure relief valve, 6 - head screws, 7 - front cover assembly, 8 - outer rotor, 9 � dowels
- the two setscrews (1) and the suction pipe (2).
- the joint (not shown) from the suction pipe. Discard the joint.
- the setscrews (3). Remove the assembly of the engine oil pump from the cylinder block.
If necessary, remove the pressure relief valve (5) from the housing of the engine oil pump (4). If necessary, remove the allen head screws (6) and the front cover assembly (7).
- the outer rotor (8) from the housing of the engine oil pump (4). Do not remove the dowels (9) from the housing of the engine oil pump unless the dowels are damaged.
Installation Procedure
If necessary, install the pressure relief valve (5).
If necessary, lubricate the internal components for the assembly of the engine oil pump with clean engine oil.
Install:
- the outer rotor (8) and the front cover (7) to the housing of the engine oil pump (4).
- the allen head screws (6). Tighten the allen head screws to a torque of 22 N�m (16 lb ft). Ensure that the two dowels (9) are correctly located in the housing of the engine oil pump (4). Position the assembly of the engine oil pump onto the cylinder block. Ensure that the dowels in the housing of the engine oil pump are aligned with the holes in the cylinder block.
- the setscrews (3). Tighten the setscrews to a torque of 22 N�m (16 lb ft). Check the backlash between the idler gear (10) and the crankshaft gear.
- the suction pipe (2) and a new joint (not shown) to the assembly of the engine oil pump.
- the setscrews (1). Tighten the setscrews to a torque to 22 N�m (16 lb ft).
- the components of the support bracket. Ensure the correct location and orientation of the bracket and the retaining clip. Tighten the setscrews finger tight in order to align the components of the support bracket. Tighten the M10 setscrew to a torque of 44 N�m (32.5 lb ft). Tighten the M8 fasteners to a torque of 22 N�m (16 lb ft).
- the engine oil pan.
