Removal
WARNING
Accidental Start-up. Disconnect the negative battery
cable, then the positive battery cable when working
on unit. Failure to do so could result in death
or serious injury.

negative (-) battery terminal.
2. Remove positive battery cable (red) (A) from
positive (+) battery terminal.
3. See Figure 5-12. Install rubber protective cover
(C) over positive (+) battery terminal.
4. Loosen two screws with nylon washers to release
battery hold-down clamp from battery tray, or

Check and Adjust V-Belt

Check the V-belt deflection. Too little belt deflection
accelerates belt wear, while too much deflection causes
the pulley to idle, overheats the engine, and creates a no-
load condition. Check and adjust belt deflection as
follows:
1. On right side of enclosure, loosen two clamps at
each end of turbocharger exhaust outlet pipe.
Remove pipe, clamps and rubber couplings from
engine.
2. Remove four screws with nylon washers to release
fan guard from radiator shroud.
3. Perform visual inspection as follows:
•
Inspect belt for cracks, fraying, excessive wear or
other damage.
•
Verify belt is free of grease and oil. Replace belt if
contaminated.
