OIL RELEASE VALVE AND INDICATOR
!
This unit is very reliable and should require no m;intenar.ce other than cleaning.

Vv'hen'the oil is changed it is advantageous to dismantle this unit and thoroughly
wash
it in petrcl to ensure that the piston works freely in the release valve body.
Under no circumstances should the release valve springs be t2mpered with as the
spring poundage
is set to give the correct oil pressure. Should it be necessary to
/I .'
replace these springs at any time, gencine Triumph spares should be obtained.

OIL PIPES (TANK TO ENGINE)
When replacing the oil pipes to the rubber connections, care must be exercised to
prevent chafing the inside of the rubber connection. Failure to observe this may
result in a small piece of rubber entering the oil system, which, on reaching the oil
pump would cause lack of pressure to the crankshaft. Foreign matter in the scavenge
pipe line above the
pump would be returned to the tank (in exceptional cases
it may
block the rocker oil feed) and
is prevented from entering the oil system by the tank
filter.

CRANKCASE SCAVENGE PIPE
In the unlikely event ol this cracking or an
air leak bctwcen the pipe and the crank-
case, the oil will not scavenge from the crankcase. Trouble of this kind would only
make itself known when the engine
is hot. A simple method by which the tube can
be tested
is to first remove the crankcase sump plate and filter and then attach a
length of rubber tubing over the scavenge pipe. Place the open end of the rubber
tube in the mouth and suck. If the tubing collapses, this will prove the air tightness
of the scavenge pipe. On the other hand if the tube does not collapse, a leak
is
evident. To rectify this fault, the e'ngine must be removed from the frame and
stripped.
VALVE ROCKERS, ROCKER SPINDLES AND PUSH RODS
The oil feed to the rocker spindles
is supplied from the scavenge side of the main oil
i
supply.
Lack of lubricant to the rockers can only be caused by a stoppage in the oil
!
pipe line.
The obvious course
is to remove the pipe and check by forcing air through
it.
To check the oil supply
at the spindle, run the engine rill ir is warm to increase
the oil temperature and then slacken off the two acorn nuts, which secure the oil
