SERVICING
14 Servo steering
The oil level in the servo steering should
be checked every 10 000 km (6000 miles).
Before checking wipe the oil container
clean. Then remove the cap and check the
l evel with the engine not running. The oil
l evel should be about '/4" (5-10 mm)
above the level mark in the container. If
the level is lower than this, top up with
oil, with the engine stopped to prevent air
from being sucked into the container. Start
the engine and recheck the oil level, which
should now fall to the level mark. When
the engine and re-check the oil level, which
about 5-10 mm ('/4") above the mark.
The oil and filter in the servo steering do
not need replacing other than during re-
pairs or reconditioning.
15 Brake fluid
The brake system is fitted with a tandem-
type brake fluid container with a section
for each circuit but with the same filler
hole. The brake fluid level should be be-
tween the "Max" and "Min" marks.
( For right-hand drive, check also clutch
fluid level.)
ENGINE
16 Crankcase ventilation
The engine is provided with positive crank-
case ventilation which prevents the gases
i n the crankcase from being released into
the atmosphere. Instead, they are sucked
i nto the intake manifold and take part in
the combustion process whereupon they
are blown out through the exhaust pipe
together with the other combustion gases.
Every 40 000 km (24 000 miles) remove and
clean the nozzle (1), the hoses (2 and 3)
and the flame protector (4). Rubber hoses
should also be replaced if they are in a
poor condition.
Brake fluids meeting the require-
ments according to SAE J 1703
should be used for the hydraulic
brake system. Brake fluid with de-
signation SAE 70 R 3 can also be
used.
