Lubricating System

The maintenance of the lubricating system is of utmost importance. Good care makes your engine last longer and saves you trouble.

The engine is pressure-lubricated with a camshaft-driven lubricating pump, which feeds oil to the bearings and other lubricating points. The system has a built-in main-flow filter through which the oil passes.

Technical Specification

  • Oil class: API D (CD) or range III
  • Viscosity: 20 W-20, 20 W-40, or SAE 30
  • Examples:
    • Shell Rotella TX 20 W-30
    • Rimula 30
    • Essolube D3-20 W-30
  • Oil filter element: FRAM PH8A
  • Buzzer: Alarm when the oil pressure danger limit is reached.
  • Red warning light: Indicates danger limit.

Oil Pressures

  • Hot engine: 3.5 – 4.0 kp/cm² at 1800 RPM
  • Danger limit: 1.5 kp/cm² at 1000 RPM

It may occur that the oil pressure rises to about 4.5 kp/cm² when the oil is cold. It may also happen that the pressure drops to 1.5 kp/cm² when the engine is hot and in neutral. However, it will rise again at increased revolutions.

Measures to Be Taken If Something Is Faulty

  1. Check the oil level, top up if necessary, and check that no oil is leaking out anywhere.
  2. If the gauge does not indicate proper pressure even after taking the above measures:
    • Check if the indicator moves when you switch the power on and off (engine not running).
    • Arrange a short circuit between the wires of the pressure gauge sensor. If the indicator moves, the sensor is faulty.

The indicator doesn’t move if it is faulty itself. The sensor is fitted to the oil pan, port side of the engine.

  1. Open the engine oil filling cap. Dry one rocker arm and start the engine. If oil flows through the hole in the rocker arm, you may continue running until the gauge can be checked.

Oil Change

The first oil and filter change is due after the first 15-20 running hours and after that every 200 running hours, or once a season. Before going to sea, and every 10 hours, check the oil level.

The dip-stick is on the port side of the engine, close to the starter motor. The oil level should never be below the “safe” mark. Change the oil of the injection pump once a season and check the oil level at least twice a season (see engine manual).

Oil Filter Change

For instructions on how to change the filter, see Ford Manual, page 21.

During the first 100 hours, the oil level should be checked daily. The oil consumption will diminish after the first 100 running hours.
