fuel hoses, hydraulic lines, electrical harness or
other parts while installing the engine.
14.Check all wires, control cables and hoses to make
sure that they are not contacted by rotating or moving
parts.
B. Reinstall engine to the machine. Make sure fastener holes of the engine are aligned with the holes in
the machine frame.
15.Connect positive (+) and then negative (–) battery
cables at the battery.
C. Secure engine to the frame with four (4) cap
screws and flange nuts. The front two (2) cap screws
should be positioned down through engine and
