other person guides the engine into the machine.
IMPORTANT: Make sure not to damage the engine,
fuel and hydraulic lines, electrical harness, or other
parts while installing the engine.
4. Slowly lower engine into the machine.
5. Align engine to the rubber engine mounts and secure
with cap screws, rebound washers, and flange head
locking nuts.
6. Secure fan shroud to the radiator with four cap
screws, flat washers, and locknuts. Make sure that
clearance between shroud and fan is at least .180" (4.6
mm) at all points.
7. Install coolant reservoir bracket and reservoir to fan
shroud.
8. Connect throttle cable to the speed control lever with
washer and lock nut. Install cable to mounting bracket
