The rocker arm shaft is oriented using a full dog point
screw.
The shaft bearing greasing holes are directed towards
the camshaft (the oil passes through the rocker arm
shaft bearings).
Rocker arms
The inlet and exhaust rocker arms are identical and
both have an oil way to lubricate the cams on the
camshaft.
Refitting
Place the bearing (E) on the shaft and fix it so that the
greasing holes point towards the bearing plate.
Then fit:
– a rocker arm,
– a spring,
– another rocker arm,
– an intermediate bearing, offset (F) pointing to the
flywheel.
Continue refitting in the same order, fit the cap with a
new oil filter and tighten to a torque of 2 daNm.
This torque has to be respected as the rocker arm
shaft is only kept rotating by the full dog point screw on
the bearing (E).
REBUILDING THE CYLINDER HEAD
Fit new valves, grind them gently into their respective
seats. Clean all the parts thoroughly, mark them for
identification purposes, then carry out the refitting
operation.
Oil all the parts.
