PROBLEM

The dual-induction lines on certain 789C Off-Highway Trucks may interfere with surrounding hardware. If there is interference a hole could wear in the intake tube which could lead to engine damage. The front engine support tube has been changed to address the interference, and the brackets have been improved to provide better intake tube alignment and additional clip points for surrounding hoses.
