LXI SUSPENSION ISSUE

[davidbrady]

Hi Greg

I've spent a little time with Al's coach and noticed that the steer tag air pressure does run significantly higher than the fixed tag; it's a passive caster steer by the way. Turns out there's a mechanical advantage that the fixed tag air springs enjoy. In the fixed variety the springs are mounted aft of the axle bolt on location; whereas, with the steer the air springs are mounted between the axle bolt up locations and the frame torque arm mounts. My fixed tag LXi ran 55 psi of air pressure at the tag; Al's runs closer to 100.

Al, something you may want to check is your air compressor governor cycle pressures. The air compressor should cut in at 100 and out at 125 psi. Since your tag pressures are so close to your lower cut in pressure it'd be wise to make sure that your compressor and governor stuff are performing properly - your tag axle air pressures don't give you a lot of wiggle room.
