Engine Installation<br />
1. If removed, install engine mount brackets to the engine<br />
using Figure 10 as a guide.<br />
2. Connect hoist or lift to the front and rear lift tabs on<br />
engine.<br />
3. Position fan shroud around the engine fan.<br />
CAUTION<br />
One person should operate lift or hoist while the<br />
other person guides the engine into the machine.<br />
IMPORTANT: Make sure not to damage the engine,<br />
fuel and hydraulic lines, electrical harness, or other<br />
parts while installing the engine.<br />
4. Slowly lower engine into the machine.<br />
5. Align engine to the rubber engine mounts and secure<br />
with cap screws, rebound washers, and flange head<br />
locking nuts.<br />
6. Secure fan shroud to the radiator with four cap<br />
screws, flat washers, and locknuts. Make sure that<br />
clearance between shroud and fan is at least .180” (4.6<br />
mm) at all points.<br />
7. Install coolant reservoir bracket and reservoir to fan<br />
shroud.<br />
8. Connect throttle cable to the speed control lever with<br />
washer and lock nut. Install cable to mounting bracket<br />
(Fig. 12). Adjust throttle cable (see Operator’s Manual).<br />
9. Connect fuel line to the injection pump fitting (Fig.<br />
12).<br />
IMPORTANT: Support hydraulic pump assembly to<br />
prevent it from falling and being damaged.<br />
10.Install hydraulic pump assembly to engine (see<br />
Pump Assembly in Chapter 4 − Hydraulic Systems).<br />
11.Connect two wires to neutral switch on traction<br />
pump.<br />
12.Connect wires and/or electrical connections to the<br />
following electrical components:<br />
A. The temperature sender and alternator (Fig 11).<br />
B. The engine run solenoid and fuel pump (Fig. 13).<br />
C. The high temperature shutdown switch and glow<br />
plug (Fig. 14).<br />
D. Battery, frame, and wire harness ground to the<br />
engine block (Fig. 15).<br />
E. The starter (Fig. 15) and low oil pressure switch<br />
(near starter).<br />
13.Install air cleaner assembly to the engine (see Air<br />
Cleaner Installation).<br />
14.Install exhaust system to machine (see Muffler<br />
Installation).<br />
15.Connect coolant hoses to the radiator. Make sure radiator<br />
drain is shut. Fill radiator and reservoir with coolant<br />
(see Operator’s Manual).<br />
16.Check position of wires, fuel lines, hydraulic hoses,<br />
and cables for proper clearance with rotating, high temperature,<br />
and moving components.<br />
17.Position battery to machine. Connect positive battery<br />
cable first and then negative battery cable. Secure<br />
battery to machine with strap and cover.<br />
18.Check and adjust engine oil as needed (see Operator’s<br />
Manual).<br />
19.Check and adjust hydraulic oil as needed (see Operator’s<br />
Manual).<br />
20.Bleed fuel system (see Operator’s Manual).<br />
21.Operate hydraulic controls to properly fill hydraulic<br />
system (see Charge Hydraulic System in Chapter 4 −<br />
Hydraulic Systems).<br />
