1993 Mack RD recalls 3
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
- Air system blockage in the air dryer occurs degrading the moisture removing capabilities of the dryer when the vehicle is operated in a cold environment and moisture accumulates and freezes in the air dryer or in the line between the dryer and the air system reservoir. The air dryer can become overpressurized causing the air dryer cartridge to separate from the mounting base.
- The risk
- If the air dryer separates from the base, the cartridge can separate sufficiently enough to cause personal injury or property damage.
- The fix
- Dealers will equip air systems with a pressure relief valve to be located between the compressor and the air dryer. This pressure relief valve is intended to vent if excessive pressure develops in the air dryer.
- The problem
- The carrier yoke bolts were manufactured with worn rolling thread dies, causing stress concentrations which caused cracks during the quenching process.
- The risk
- This condition can cause bolt failure and allow thedriveline to separate from the carrier assembly.
- The fix
- REPLACE THE CARRIER YOKE BOLTS.
