1985 Mack MH recalls 5
Recall repairs are free. Your dealer fixes them whether or not you bought the car there - check your VIN at nhtsa.gov/recalls to see if yours is done. What to do
- The problem
- Left or right cab step may crack in its welded area due to flexing of the step during entering and exiting. Consequence of defect: as the cracks extend, the tubular step could partially collapse and break without warning to the user, and could result in personal injuries.
- The fix
- Install a reinforcement brace if no cracks are found. In addition, replace step if cracks are present.
- The problem
- The dual double check valve may not release the proper air volume to the brake system, causing a slight timing delay between the tractor and the trailer brake system. Consequences of defect: if the brakes are suddenly applied, the trailer could jackknife without warning to the operator, which could result in a vehicle crash.
- The fix
- Install two new sleeves in the dual double check valve which will increase air flow.
- The problem
- The drag links may have been installed incorrectly allowing drag link clamp bolt to axle beam interference. Consequence of defect: during a turning maneuver, increased steering effort or complete lockup of steering could occur without warning. This could result in loss of truck control and a crash.
- The fix
- Assure that drag links are installed to correct interference condition.
- The problem
- The flip out step clevis on the bumper may fail and break under the weight of the person standing on the step to service the front area of the vehicle. Consequence of defect: this sudden break will cause the person standing on the step to fall, without warning, and could result in injuries.
- The fix
- Remove the step clevis and replace with a new improved clevis.
