Inspect packings, ceramic pistons and connec$ng rod connec$on
1.
Remove the pump from the engine. Then using a 12 mm
Allen wrench remove the pump manifold bolts. See sec-
on 5.2.1 for part iden fica on.
2. Remove the pump mani-
fold. If needed, some mes
turning the cranksha? can sup-
ply a gap between the mani-
fold and crankcase. This will
allow space to put two screw
drivers in the gap to be used
lightly as pry points.
3. Use a dirty or greasy rag to wipe the ceramic piston. This
will help to inspect ceramic piston for damage and/or cracks.
Replace if needed. Make sure to clean piston prior to pu>ng
pump back together.
4. Push and pull on
each piston to check for
any play in the con-
nec ng rod, piston
guide, wrist pin or piston
bolt. If there is significant
movement replace
pump.
5. Remove packings from manifold.
6. Inspect packings, brass retainer, head ring and O-ring for
wear and/or damage. Replace if needed.
7. Install packing assemblies into manifold.
8. Grease pistons and
packings with white lithium grease.
9. Install manifold onto pump.
Make sure to torque manifold
bolts. See sec on 7.3 for torque
specifica ons if needed.
