On CELECT™ engines, remove the lubricating oil tem-
perature sensor from the lubricating oil pump cover.
Lubricating oil pumps on N14 STC engines are equipped
with a 9/16-18 UNF CompuchekT 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 (CELECT™ engines),
or 9/16-18 UNF CompuchekT coupling nipple (STC en-
gines).
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.
