Caution: The lubricating oil system must be primed before operating the engine after any internal engine repairs or extended engine storage (beyond 6 months) to avoid internal component damage. Do not prime the
system from the bypass filter; the filter will be damaged.
On CELECTTM engines, remove the lubricating oil temperature sensor from the lubricating oil pump cover.
Lubricating oil pumps on N14 STC engines are equipped with a 9/16-18 UNF Compuchekா coupling nipple. Use
the coupler, Part No. 3376859, to connect the priming pump to the coupling.
Install the priming pump oil supply hose to the lubricating oil pump coupling. Use clean 15W-40 lubricating oil from
a drum or a container. Supply oil to the lubricating oil pump and engine.
Allow the oil to flow until the oil pressure gauge indicates a maximum pressure of 210 kPa [30 psi] at the main oil
rifle to prime the lubricating oil system.
Remove the priming pump oil supply hose and install the lubricating oil temperature sensor (CELECTTM engines),
or 9/16-18 UNF Compuchekா coupling nipple (STC engines).
Torque Value: Plug 34 N•m [25 ft-lb]
Sensor 34 N•m [25 ft-lb]
Wait 10 minutes to be sure the lubricating oil has drained into the oil pan. Use the dipstick to measure the oil level.
Fill the oil pan to the specified ‘‘high’’ level.
NOTE: If an external pressure pump is not available, prime the lubricating system as follows:
Use the dipstick to measure the lubricating oil level.
Fill the oil pan to the ‘‘high’’ level mark on the dipstick.
Disconnect the turbocharger lubricating oil supply line.
Pour 50 to 60 cc [2.0 to 3.0 fl oz] of clean 15W-40 oil in the turbocharger oil supply line fitting.
Install the turbocharger oil supply line.
Torque Value: 30 N•m [22 ft-lb]
Use clean 15W-40 oil to fill the lubricating oil filter.
Tighten the filter until the gasket contacts the filter head surface.
Tighten the filter an additional three-fourths to one (3/4 to 1) turn.
Disconnect the electrical wire that supplies power to the fuel pump solenoid.
NOTE: The manual override screw must be turned counterclockwise until it stops.
Caution: Do not crank the starting motor for more than 30 seconds. Excessive heat will damage the starting
motor.
Crank the engine until the oil pressure gauge indicates a positive pressure.
NOTE: If a positive pressure is not indicated within 30 seconds, stop cranking the engine and allow 2 minutes for the
starting motor to cool before cranking the engine again.
NOTE: If a positive oil pressure is still not indicated, find and correct the problem before continuing.
Wait 10 minutes to be sure the lubricating oil has drained into the oil pan. Use the dipstick to measure the oil level.
Fill the oil pan to the specified ‘‘high’’ level.
Use clean 15W-40 oil to lubricate the fuel filter gasket.
Fill the filter with clean fuel.
Install the filter on the filter head and tighten the filter until the gasket contacts the filter head surface.
Tighten the filter an additional one-half to three-fourths (1/2 to 3/4) turn.
