Maintenance Procedures Every 2000 Hours or Yearly 8000 SRM 707
• Check the Pressure Trim Valve (PTV) electrical
connection. Make sure the connector is seated
and locked, check mounting bolts, and check for
external damage.
• Check regulator is securely mounted.
NOTE: During normal operation, oil may buildup
inside the secondary chamber of the LPR. This may
be a result of poor fuel quality, contamination of
fuel supply chain, or regional variation of the fuel
makeup. To correct these problems, drain oil period-
ically.
CAUTION
Disposal of lubricants and fluids must meet lo-
cal environmental regulations.
To drain the oil from the LPR follow these steps:
NOTE: Drain oil from the LPR when the engine is
warm. This will help the oil flow freely from the LPR.
1. Move the equipment to a well ventilated area
with no ignition sources.
2. Start engine.
3. Close manual value with engine still running.
4. When the engine runs out of fuel and stops, turn
the key to OFF.
5. Disconnect negative battery cable.
WARNING
A small amount of fuel may still be in the fuel
line. Use gloves and eye protection to prevent
injury. If fuel continues to flow from the con-
nections when loosened, make sure the manual
valve is completely closed.
6. Slowly loosen and disconnect inlet fitting.
7. At the outlet hose fitting, loosen clamp and re-
move hose.
8. Remove and retain locking pin in the outlet fit-
ting and remove outlet fitting from the LPR.
9. Disconnect PTV connection, and vacuum hose.
10. Remove two LPR mounting bolts.
11. Put a drain pan in engine compartment.
12. Rotate LPR to 90 degrees, so the outlet fitting is
pointing down into the drain pan. Drain LPR.
13. Inspect secondary chamber for dried particles
and remove.
14. Remove drain pan and reinstall LPR with the
two retaining bolts.
15. Reinstall outlet fitting and secure with locking
pin.
16. Reconnect PTV electrical connection, push con-
nector until it locks ("clicks") into place. Pull con-
nector to check it is locked. Connect vacuum line.
17. Reconnect the outlet hose and hose clamp.
18. Reinstall fuel inlet line and tighten connection.
NOTE:
Open manual valve slowly to prevent activat-
ing the Excess Flow Check Valve.
19. Slowly open manual service valve.
20. Check for leaks at inlet and outlet fittings and
coolant line connections.
21. Use soapy solution or electron leak detector. If
leaks are found, make proper repairs.
22. Start the engine and recheck for leaks at regula-
tor.
23. Dispose of any drained material in a safe and
proper manner.
CHECK THROTTLE SHAFT FOR STICKING
Check Throttle body return action to ensure throttle
shaft is not sticking. Repair if necessary.
INSPECT EXHAUST MANIFOLD AND
PIPING FOR LEAKS
To check the exhaust manifold and piping for leaks,
preform the following:
• Check the exhaust manifold at the cylinder head
for leaks. Ensure that all bolts and shields are in
place.
• Check exhaust pipe fasteners to manifold for leaks
to ensure they are tight. Repair if necessary.
• Check all exhaust pipe extension connectors for
leaks and tighten, if necessary.
