- What is wrong
- The hand throttle cable may be mis-aligned with the accelerator rod causing the hand throttle cable to "saw" into the accelerator rod. This can cause the accelerator and hand throttle cable to bind in a partial or full throttle position.
- Risk
- Should the accelerator rod and hand throttle cable bindin partial or full throttle position, loss of vehicle control could occur,resulting in an accident.
- Remedy
- Navistar dealers will replace the present accelerator rod with a new accelerator rod with a hardened end. Owners are advised to disconnect the hand throttle until a new accelerator rod is available.
