3.Remove the valve assembly from the cavity; the assembly may come apart.

4.Install the new valve. Install the o-ring and hex plug; torque to 75 ft-lb (103 NSm).

NOTE: Retorque the plug after 5 hours of operation.

Pumping Section

1.Remove the eight capscrews and lockwashers from the manifold using a 13 mm wrench.

2.Carefully separate the manifold from the crankcase.

NOTE: You might have to tap the manifold lightly with a soft mallet to loosen it.

CAUTION

To avoid damage to the plunger or seals, keep the manifold properly aligned with the ceramic plungers when you remove it.

3.Carefully examine each plunger for any scoring or cracking, and replace as necessary.

Servicing the Plungers

NOTE: Plunger repair kit 801474 is available to replace retainers, o-rings, washers, and backup rings for three cylinders.

1.Loosen the plunger retaining screw five to six turns using a 10 mm wrench. Push the plunger towards the crankcase to separate the plunger and retaining screw.

2.Remove the screw from the plunger, and examine the o-ring, backup ring, and copper bearing/gasket washer. Replace these parts, if necessary.

3.Remove the plunger and flinger from the plunger shaft. Clean, examine, and replace parts as necessary.

4.Inspect the plunger shaft for oil leakage from the crankcase. If leaking is obvious, replace the oil seals. Otherwise, DO NOT remove these seals because they cannot be reused. Oil Seal Kit 801473 is available for replacing the seals.
