N.B. Make sure that the
dipstick rests fi rmly on the
edge of the threaded hole.
Gearboxes are normally fi tted with yellow oil level plugs. Level plugs may be of the spill type or may require
a dipstick (not supplied) to be inserted. In other cases, yellow level plugs have dipsticks incorporated.
To check the oil level using a spill type level plug, fi rst identify the yellow level plug. Remove the plug and
insert into the hole a rod of suitable size and of the shape shown in the fi gure.
If the level is more than 3 mm below the spill level, top up and check the reason for the drop in oil level.
If the level plug has a dipstick incorporated, simply identify it by its yellow colour, remove it, and check that
the level lies between the MIN. and MAX. markings.
If the level lies outside these marks, restore the correct level and identify the causes of the incorrect level.
The correct method for checking oil level by inserting a rod (not supplied) through the yellow level plug is
described on the following pages.
6.3 OIL CHANGES
1. Place a suitable container under the drain plug.
2. Remove the fi ller and drain plugs and allow the oil to drain out.
3. Wait for a few minutes to ensure all the oil has drained out. Thoroughly clean the drain plug magnet (if
fi tted), fi t a new seal and refi t the drain plug.
4. With the gearbox installed in its fi nal mounting position, fi ll it with oil to the mid point of the sight glass, or
to the reference notch on the dipstick, or until oil starts to fl ow out of the level hole.
5. Fit a new seal, replace and tighten the fi ller plug.
See the “LUBRICATION” section in this manual for details of the quantity of oil required. Specifi ed
quantities are only approximate. Gearboxes must be fi lled to the mid point of the sight glass, or to
the reference notch on the dipstick, or until oil starts to fl ow out of the oil level hole, according to
the mounting position specifi ed on order.
Apply Loctite 510 (or a product with similar properties and application range) on the thread of plugs.
