Manual Transmission Variable Idle

Control

NOTE

If your truck is equipped with a manual

transmission, your engine idle RPM may

vary under certain conditions. The en-

gine control module will control the RPM

based on various inputs such as vehicle

weight, rear axle ratio, road grade and

altitude. When starting from a stop, de-

pending on these conditions, the engine

RPM may increase to compensate for

load in order to ensure a smooth transi-

tion into motion.

Engine Operating Range

Proper Engine Operating Range

Full throttle rpm

Peak torque

CAUTION

Operating the engine at full throttle be-

low peak torque will shorten engine life

to overhaul, can cause serious engine

damage, and is considered engine

abuse. DO NOT operate the engine at

full throttle operation below peak tor-

que rpm for more than 30 seconds.

Failure to comply may result in equip-

ment or property damage.

PACCAR engines are designed to operate

at full throttle under momentary conditions

down to peak torque engine speed. This is

consistent with recommended operating

practices.

CAUTION

Operating the engine beyond the max-

imum engine speed can cause severe

engine damage. Use proper operating

techniques for the vehicle to prevent

engine overspeed. See Engine Speci-

fications for maximum engine speed.

Failure to comply may result in equip-

ment or property damage.
