Carefully clean the surface of the head on which the rocker
arm cover rests.
Using the magnetic support 99370400 (2), as shown in the fi-
gure, arrange the dial gauge (0-30mm) 99395606 (1) with the-
flatbasedrod(3)positionedontherockerarmroller(4)which
controls the exhaust valves of cylinder no. 3 and preload to at
least 7 mm.
Position the flat based dial gauge so that its axis pas-
ses through the centre of the roller on which it is
resting.
During the CHECK phase, not during the engine
overhaul phase, the allowed tolerance of the mea-
surement is between -0.05 - +0.12 mm.
The allowed measurement tolerance during
OVERHAUL is ± 0.05 mm.

Using the specific tool to turn the engine flywheel 99360321,
turn the crankshaft in the opposite direction to that of opera-
tion until the pointer of the dial gauge reaches the minimum
value beyond which it can no longer fall.
NOTE The measurement must be taken holding the
rocker roller in contact with the profile of the
exhaust cam of the camshaft.
reset the dial gauge
NOTE The dial gauge is to be zeroed with the rocker arm
roller in contact with the base radius of the cam
profile .
This occurs when the flywheel is turned in the op-
posite direction of the operating direction approx.
1 and 1/4 rotations.
