NHTSA Campaign 91V177000

VEHICLE SPEED CONTROL:SPRINGS

Issued by FREIGHTLINER CORPORATION · Reported Oct 15, 1991 · 420 vehicles affected

What's wrong

THE HOOK SIZE OF THE THROTTLE RETURN SPRING IS TOO SMALL RESULTING IN A TIGHT FIT AROUND THE ANCHOR NUT, CAUSING THE THROTTLE RETURN SPRING TO BREAK PREMATURELY.

Consequence

IF THE THROTTLE SPRING BREAKS, THE ENGINE WILL RETURN TO IDLE SPEED, WHICH MAY CAUSE A HIGHWAY HAZARD AND RESULT IN A VEHICLE CRASH.

Remedy

INSTALL THROTTLE RETURN SPRINGS WITH LARGER HOOKS.
