(1) The gearbox is fitted with a dipstick and oil filler plug, see fig 2e.
(2) Each engine is supplied with a gearbox operators manual which specifies
the type of lubricating oil to be used, the capacity and frequency of
changing of the oil.
(3) New engines are normally supplied with the gearbox topped up with
lubricant but Check the level before starting the engine for the first time.
(4) The oil can be changed via the drain plug at the bottom of the box or
sucked out with a hand pump via the filler plug.

FUEL SYSTEM
(see page 24 for a typical installation)
IMPORTANT
• Always fit a fuel/water separator in the fuel supply system. Water in the fuel can seriously damage the injection
system.
• If a fuel supply shutoff valve is fitted do not use a taper tap, only use a ball valve tap. The ball valve type are more
reliable and less likely to let air into the fuel system.
• Be sure to use a strainer when filling the fuel tank. Dirt or sand in the fuel may cause trouble in the fuel injection
pump.
• Always use diesel fuel.
• Do not use kerosene, which is very low in cetane rating, and adversely affects the engine.
• Be careful not to let the fuel tank become empty, or air can enter the fuel system, necessitating bleeding before
next engine start.
• The fuel lift pump will only lift fuel through 0.25 metres. If this is insufficient then an electric fuel lift pump must
be fitted. Drawing 202-06421, illustrating recommended wiring for this pump can be supplied upon request.
FUEL FILTER REPLACEMENT
1. The fuel filter is a spin on type. Remove by turning anti-clockwise when
viewed from below.
2. Replace the fuel filter cartridge every 750 hours or every 2 years. See fig. 2g.
3. Apply fuel oil thinly over the gasket and tighten into position - hand tight.
4. Bleed as detailed - see initial start up.
5. Check for leaks.
6. Do not get fuel on the flexible mounts.
