before installing.

3. Grasp valve retainer by tab at the top with pliers and

remove from valve chamber. Valve parts usually

separate during removal.

Note:

A special tool will be needed to remove the seat
from the manifold. A reverse pliers or a
standard vise grip and a 1/4” x 3” bolt to fit I.D. of
seat inserted under the edge of the seat, will pry
the valve seat out easily.

preassembled valve assembly in service kit

containing retainer, spring, valve, valve seat, o--ring,

and back--up ring.

5. Grasp new valve assembly by tab at top with pliers,

immerse in oil and push into valve chamber. Be

certain valve assembly is square in valve chamber.

6. Apply Loctite 242 to valve plug, thread into manifold

port and torque per chart.

Note

:

Corrosion Resistant models require the coil
spring installed in the Valve Plug.

Servicing the Pumping Section

Disassembly:

1. Remove the four (4) hex nuts or two (2) bolts from the

manifold (varies with model).

2. Rotate crankshaft by hand to start separation of

manifold from crankcase. Support the underside of

the manifold and tap lightly with a mallet to remove

the manifold assembly.

CAUTION

Keep manifold properly aligned with ceramic

plungers when removing to avoid damage to

either plungers or seals.

3. Remove oil pan and slide out seal retainer with wicks.

4. Using a wrench, loosen the plunger retainer. Grasp

ceramic plunger and push toward crankcase until

plunger retainer pops out.

5. Remove plunger retainer with copper gasket,

back--up Ring and o--ring.

6. Remove plunger from plunger rod.

Reassembly:

1. Carefully examine each ceramic plunger for scoring

or cracks, replace if worn and slip onto plunger rod.

Note:

Ceramic plunger can only be installed one
direction (front to back). Do not force onto rod.

2. Examine plunger retainer and stud and replace if

worn.

Note:

Thread stud into plunger retainer.

3. Examine o--ring, back--up ring and gasket on plunger

retainer and replace if worn or cut. Lubricate o--ring

for ease of installation and to avoid damaging

o--rings.

Note:

First install gasket, then back--up ring and
o--ring.

4. Thread plunger retainer and stud assembly into

plunger rod. Exercise caution not to over torque.

5. Saturate new oil wick by soaking in oil, place in seal

retainer and slip retainer over ceramic plunger.

6. Replace oil pan.

7. Turn shaft by hand to line up plungers so end

plungers are parallel.

8. Carefully slip manifold onto plungers, keeping

manifold level, and tap with mallet to bring manifold

flush with crankcase.

9. Replace washers and nuts or bolts and torque per

chart.
