Servicing Valves on the High Pressure Pump
Removing a Valve
1.
Remove the valve cap and extract the valve assembly (see Figure 5-1).
2. Remove the valve assembly (retainer, spring, valve plate, valve seat) from the valve
cavity.
3. Remove the O-ring and support from the valve cavity.
4.
Examine the O-ring and replace if there is any evidence of cuts, abrasion, or
distortion.
5. Inspect the manifold for wear or damage (see Figure 5-2).
6. Inspect the old valves for wear or damage. Only one valve kit is necessary to repair
all the valves in the pump. (The kit includes new supports, O-rings, valve seat, valve
poppet, spring and retainer; all are pre-assembled.)
