(19) Remove the rubber air tube connecting the
turbocharger to the air cleaner housing.
(20) The engine can be rotated with a barring tool
such as Snap-On No. SP371, MTE No. 3377371
(Cummins Tool Division), or an equivalent.
(21) The opening for the barring tool is located in
the rear flange of engine on exhaust manifold side

(22) Insert the barring tool into the flywheel hous­
ing opening (Fig. 91).
(23) While holding tension on the timing pin
(towards front of engine), very slowly rotate the
engine (counterclockwise as viewed from front) with
the barring tool. Rotating the barring tool counter­
clockwise will rotate the crankshaft clockwise. Con­
tinue to rotate until the timing pin drops into the
machined hole in the back of the camshaft gear.
When the pin aligns to the gear, the engine is now at
the TDC position (compression stroke) at cylinder
number 1.
CAUTION: When installing the fuel injection pump
and to achieve proper injection pump timing, the
engine MUST be in the TDC position (compression
stroke) at cylinder number 1.
Before proceeding to the next step, and to
prevent shearing of the timing pin, temporarily
remove the timing pin from the back of the
gear.
(24) Remove the nut and washer retaining the
injection pump gear to the injection pump shaft (Fig.
92).
(25) Place a shop towel below the retainer nut i n
the gear housing cover opening to prevent the nut or
washer from falling into the gear housing.
CAUTION: If the gear retainer nut or washer drops
into gear housing, cover must be removed to
retrieve them before engine is started.
(26) Use a T-bar type puller (Fig. 93) to separate
the injection pump gear from the injection pump
shaft. Attach two M8 X 1.24 M M (metric) screws
