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 sec- tion). 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 send- er 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 en- gine block.

E.The starter and low oil pressure switch (near starter).

11.Install air cleaner assembly to the engine (see Air Fil- ter System Installation in this section).

12.Install exhaust system to machine (see Exhaust Sys- tem Installation in this section).
