INSTALLATION SERVICE POINTS
ALASH ADJUSTER INSTALLATION
Caution
If the lash adjuster is re-used, clean the lash adjuster.
Fit the lash adjuster onto rocker arm without allowing diesel
fuel to spill out.
BCAMSHAFT INSTALLATION
(1) Apply engine oil to the journals and cams of the camshafts.
Install the camshafts on the cylinder head.
Use care not to confuse the intake camshaft with the
exhaust one. The intake camshaft has a slit on its rear
end for driving the crankshaft position sensor.
(2) Install the crankshaft sprocket B or spacer and flange
to one end of the crankshaft, and turn the crankshaft
until the timing marks are lined up, setting No. 1 cylinder
to the TDC.
(3) Set the camshafts so that their dowel pins are positioned
at top.
CBEARING CAP INSTALLATION
(1) According to the identification mark stamped on the top
of each bearing cap, install the caps to the cylinder head.
Only “L” or “R” is stamped on front bearing cap. Cap
No. is stamped on No. 2 to No. 5 bearing caps. Rear
bearing cap has no stamping.
I: For intake camshaft side
E: For exhaust camshaft side
(2) Tighten the bearing caps in the order shown two to three
times by torquing progressively.
Tighten to the specification in the final sequence.
(3) Check to ensure that the rocker arm is positioned correctly
on the lash adjuster and valve stem end.

at the top).
(2) Install the camshaft position sensing cylinder so that the
white paint mark is facing in the direction shown in the
illustration.
