CAUTION
The lubricating oil system must be primed before
operating the engine after it has been rebuilt to avoid
internal damage.
Priming the Lubricating System
Remove the plug.
To prime the system using external pressure, connect the
supply to a tapped hole in the main oil rifle.
Use a pump capable of supplying 210 kPa [30 psi] of
continuous pressure. Connect the pump to the port on the
main oil rifle as shown.
Use clean 15W-40 oil to prime the system until the oil
pressure registers on the gauge.
Remove the oil supply tube, and install the plug.
Tighten the plug.

on the dipstick.
If an external pressure pump is not available, prime the
lubricating system according to the following procedure:
• Fill the engine with clean 15W-40 oil to the high mark
