ADJUSTMENTS:
ENGINE SPEED AND THROTTLE LINKAGE
1.
The engine should idle at 1,200 RPM:
See Figure 7.45.
•
Slower idle speeds will result in poor idle quality,
reduced flow of cooling air, and reduced oil flow.
•
Higher idle speeds will result in harsh gear
selector action and possible internal damage to
the transfer case.
2.
Top no-load speed should be 3,850 RPM:
See Figure 7.46.
•
Slower top no-load speeds will result in dimin-
ished performance.
•
Higher top no-load speeds will result in unsafe
operating conditions and possible over-speed
engine failure.
