Technical data

(15) With the idler gear mating mark "1"
properly aligned with the crankshaft
mating mark "1", install the idler gear
onto the idler shaft. When the
crankshaft front bearing has already
been installed, the mating mark "1" on
the front side of the crankshaft is
invisible.
Align the idler gear mating mark "1"
with a mark line on the side of the gear
boss. In this case, after installing the
idler gear, press the sealant-coated
guide seal into the front and rear main
bearing caps. Note position of radius
ends - install first and outboard.
Tighten to the specified torque.
Insert the camshaft and gear assembly into the cylinder block and align the idler gear mark "2"
with the camshaft gear mating mark "2".
Subsequently insert the injection pump camshaft assembly into the cylinder block and align the
idler gear mating mark "3" with the pump gear mark "3". Finally install the high-pressure pump
drive shaft gear assembly.
(16) Confirm that mating marks on the gears are in proper alignment with each other. For the W33
engine in which its crankshaft front bearing has not been installed, press the bearing inner race
in.
(17) Install the governor weight assembly to the injection pump cam gear.
(18) Install the gear case (after installing governor and related parts) and gasket. When installing the
gear case, insert the governor tie rod and tie-rod stopper spring into a hole in the cylinder block.
(19) Insert the crankshaft pulley. Install the washer and nut.
Tighten to the specified torque.
(20) Install the combination backplate/flywheel housing. Be
sure to install the gasket.
(21) After installing the oil screen, install the oil pan.
(22) Place the engine upside down. Install the tachometer drive
unit while turning the camshaft or the gear shaft. Install the
o-ring properly. Apply silicone sealant to the outside
surface of the sleeve beforehand. Assemble drive gear unit
components in the following manner.
