SUBJECT: Throttle pedal hinge pin may break on Off-Highway Trucks, Quarry Trucks, and Wheel Tractor-Scrapers
PROBLEM:
The plastic hinge pin that is used on the following throttle pedals can wear and break, causing the pedal to separate from the base.
- 113-4799
- 201-8616
- 139-7738
- 148-5741
- 130-8176
SOLUTION:
The plastic hinge has been replaced with a steel hinge pin, nylon bushings, and retainer clips. This change is effective with machines built after April 2005 (see Table 1). A service kit with the steel pin will be available for servicing older pedals in the near future.
