32
Refilling with oil. Refer to Technical Data for quali-
ty and quantity. Refit the plug together with its
O-ring. Lower the drive. Check the oil level with
the aid of the dipstick. It must not be screwed in
when checking the level. Replenish to the correct
level through the hole for the dipstick. Oil must be
drained off if the level is too high. Fit the oil dip-
stick with its O-ring and tighten.
WARNING! Check that the oil drain plug
does not leak.
CHANGING THE OIL IN THE MS4A
REVERSE GEAR
Use the oil drain pump to suck up the oil through
33
the hole for the dipstick (1).
The reverse gear is refilled to the upper mark on
the dipstick through the oil filter hole (2). Then
start the engine and run it at idling speed a few
minutes to fill the reverse gear's oil cooler with
oil. Stop the engine and check the oil level. Add
more oil as required.

CHECKING THE V BELT
The drive belt must be changed if there are signs
34
of wear or splits. Undo the alternator's attachment
bolts 1 and 2 and take off the belt. Clean the
grooves on the pulleys before a new belt is fitted.
Tension the belt so that it can be depressed
about 10 mm (0.4") with thumb pressure half way
between the drive pulleys. Check the tension of
the belt again after a few hours of operation and
re-tension as necessary. The most satisfactory
tension is obtained if adjustment is carried out im-
mediately after the engine has been run and the
belt is warm and flexible. Use Volvo Penta origi-
nal V belts.
IGNITION SYSTEM
Any adjustment to the engine's ignition system
35
should be carried out by an authorized workshop
that has the correct equipment for the job. The ig-
nition system is sensitive and incorrect action
may have serious consequences.
The distributor must be checked on a test bench.
Use a stroboscope for checking the ignition tim-
ing. Refer to Technical Data for the timing setting.
Lubricate the distributor with a few drops of oil on
the drive spindle's felt pad under the rotor.
