Issued by CATERPILLAR TRACTOR CO. · Reported Sep 13, 1977 · 400 vehicles affected

What's wrong

THE TOP END OF THE MAIN SPRING THAT CONTROLS THE GOVERNOR IN THE SPEED CONTROL IS POSITIONED BY A TWO-PIECE SEAT. THE INSIDE OF THIS SEAT CAN WEAR AND CAUSE THE SLEEVE PORTION OF THE SEAT TO SEPARATE FROM THE WASHER PORTION. CONSEQUENTLY, THE SLEEVE CAN DROP DOWN AND LOCK THE FUEL RACK IN THE FULLY OPEN POSITION, CAUSING ENGINE OVERSPEED.

Remedy

DEALER WILL INSTALL AN IMPROVED SEAT ASSEMBLY AND GUIDES, WITHOUT CHARGE.
