3. Slowly lower engine into the machine.
4. Align engine to the engine supports and hydraulic
pump input shaft. Secure engine to engine supports with
cap screws, rebound washers and flange nuts.
5. Secure hydraulic pump assembly to engine (see
Pump Assembly Installation in the Service and Repairs
section of Chapter 4 -- Hydraulic System).
6. Thoroughly clean tapered surfaces of fan motor
shaft and fan hub. Position fan hub (with fan attached)
onto motor shaft and secure with washer and hex nut
(Fig. 15). Torque nut from 27 to 33 ft -lb (37 to 44 N -m).
7. Position upper radiator shroud and coolant reservoir
with bracket to the radiator. Secure shroud and reservoir
bracket to the radiator and lower radiator bracket with
removed fasteners (see Radiator Installation in this section).
Make sure that clearance between shroud and fan
is at least 0.180” (4.6 mm) at all points.
8. Connect throttle cable to the speed control lever with
washer and lock nut (Fig. 14). Secure cable to cable
support. Adjust throttle cable.
9. Connect fuel line to the injection pump.
10.Connect wires and/or electrical connections to the
following electrical components:
A. The dual temperature switch, temperature sender
and alternator (Fig 10).
B. The engine run solenoid and fuel pump (Fig. 13).
C. The glow plug (Fig. 11).
D. Battery, frame and wire harness ground to the engine
block.
E. The starter and low oil pressure switch (near
starter).
