- Shut off genset, recheck oil level and add oil as necessary.
Priming the Fuel System (Low-Pressure Side) maintenance
⚠ High pressure oil spray from an injector line fitting can penetrate the skin.
- Hold control switch in stop position to prime via fuel lift pump during preheat.
- If 20 seconds of priming is not enough, open the bleed screw.
- Disconnect engine harness lead from glow plugs and insulate it.
- Press STOP until fuel just appears at the bleed opening.
- Tighten bleed screw and reconnect lead to the glow plugs.
Priming the Fuel System - High-Pressure Side maintenance
⚠ High pressure oil spray can penetrate skin, leading to possible blood poisoning
Tools: flare-nut wrenches
- Loosen high pressure fittings at nozzles using two wrenches

- Shut down engine and torque fittings to 19-25 lb-ft (25-34 N-m)
Priming the Fuel System - Low-Pressure Side maintenance
⚠ Preheating more than 20 seconds reduces glow plug life
- Fuel lift pump primes during preheat when control switch is held in stop position
- If 20 seconds priming is not enough, open bleed screw and disconnect engine harness lead from glow plug bus bar
- Press STOP until fuel appears at bleed opening, tighten bleed screw
- Reconnect lead to glow plugs
Replacing Thermostat maintenance
⚠ Hot coolant is under pressure and can cause severe burns when loosening the pressure cap.
- Let engine cool, loosen pressure cap, disconnect negative battery cable(s).
- Remove the two thermostat housing bolts and pull off housing, thermostat and gasket.
- Clean off the gasket area.
- Reassemble with new thermostat and gasket.
- Apply Three Bond 1215 liquid sealant or equivalent to top side of gasket.
Replacing the Fuel Filter Element maintenance
⚠ Diesel fuel is combustible and can cause severe personal injury or death.
- Drain the filter by removing the plug and collect water and sediment.
- Reinstall plug securely and spin off the element.
- Clean the contact surface of the base.
- Lubricate the new element and its gasket and fill element with clean diesel fuel.
- Spin new element onto base and hand tighten.
- Start and run genset and check for fuel leakage.
- Tighten filter only enough to stop leakage.
Replacing the Sea Water Pump Impeller maintenance
⚠ Do not lubricate with petroleum products like grease and oil which attack impeller materials.
Tools: Two pairs of pliers
- Disconnect negative battery cable(s).
- Close the sea cock and remove impeller cover and O-ring.
- Grip vanes on opposite sides with two pairs of pliers and pull out old impeller.
- Clean out impeller pieces from heat exchanger and exhaust elbow if vanes broke.
- Install new impeller, twisting clockwise; vanes incline counterclockwise.
- Wet inside of pump and impeller with water, soap or silicone lubricant; secure O-ring and cover.
- If strainer above waterline, fill strainer with water and reinstall cover.
- Open sea cock, reconnect battery cables (negative last) and start genset.
