Troubleshooting the DynoMax Chassis Suspension Air Springs – Part 2

*Excerpted from the handy info included in the DynoMax chassis manual included in each Country Coach’s important documents box. In an earlier post here at the blogspot, I shared some additional issues and possible causes/solutions, as shared in the DynoMax Chassis Manual.

Problem: The Air Springs deflate rapidly when motorcoach is parked. Possible Cause 1: Air leakage from the air system or the air spring. Solution 1: Inflate to specifications found in you manual.  Possible Cause 2: Out of Alignment. Solution 2: Realign Steering Assembly.  Possible Cause 3: Bushings in torque arms are worn. Possible Solution 3: Replace bushings. Possible Cause 4: Air spring is under-inflated on one side. Possible Solution: Adjust height control valve.

Problem: Motorcoach is experiencing excessive sway. Possible Cause 1: Height Control Valve is clogged or not functioning. Possible Solution 1: Repair or replace height control valve. Possible Cause 2: Air spring is punctured. Possible Solution 2: Install a new air spring.

Problem: Motorcoach rides too high or low. Possible Cause: Incorrect height adjustment. Possible Solution: Readjust the Height Control Valves(refer to chassis manual “Ride Height Adjustment” section).

Problem: Air Spring is Blown. Possible Cause 1: Tires, rims, or chains rubbing the air spring. Possible Solution 1: Check the clearance between the air spring and the tire. If the tire, rim, or tire chains have contacted the inflated air spring, change to narrower tires and rims to provide clearance for tires and chains. Possible Cause 2: Air brake actuator rubbing against the air spring. Possible Solution 2: Relocate the brake actuator with factory-approved parts to provide adequate clearance.....
