Installing injection pump control bar guide sup-
ports (Fig. 2)
Install supports A with related O-rings, rollers and lockpins using
screws B into the engine block. Insert the injection pump control
bar C into the supports and tighten screws B and ensure that the
bar is free to slide inside the support. (The two supports equipped
with sliding rollers should be placed at both bar ends).
Warning - When the injection pumps are removed operate the
engine shutoff control (STOP) so as to bring the rack rod dog back
to the injection pump centre line. This permits it to be passed
through the special aperture in the engine block.
Check is made visually through the sight windows in the engine
block.
Engine timing
• valve timing
This should be carried out before injection pump calibration.
Raise the first cylinder piston to upper position; remove the rocker
arm support, remove intake valve spring and drop valve onto
piston head then insert a snap ring into the valve stem.
Fasten no. 5.9030.616.4 equipment on piston head as shown in
figure (the comparator indicating 25 mm stroke reading should be
placed on the engine valve).
After raising piston to T.D.C. position set to zero the comparator
fixed to the valve stem. When the concerned cam rest race has
been located also reset the comparator applied to the intake valve
tappet head.
Turn the crankshaft clockwise until a 17.27 mm piston stroke has
been completed. Then rotate the camshaft until a 3.93±0.1 mm
intake cam lift is obtained.
Fit the timing gear and bring the timing gear marked tooth into
contact with both idler gear marked teeth. Press on the gear
anticlockwise when tightening the securing screws until any bac-
klash between teeth is taken up.
Take the equipment and proceed with the injection pump setting
operations.
