Differential Pressure Sensor Hose & Clamp
The standard springs used on Mack CX, CH, CV, CL, RD, RB, DM, DMM, LE, MR, MRU and LEU model chassis (excluding CXN and CHN models) are designed to give the operator the smoothest ride possible. In achieving this, the chassis becomes susceptible to changes in weight that will affect chassis height and may result in chassis lean.
In most instances, chassis lean can be corrected by replacing the existing front spring spacer blocks with blocks of a different size.
The following guidelines will aid in correcting chassis lean:
Note: If the main beam members are not contacting the wear surfaces of the spring hangers on chassis equipped with an AL suspension, loosen and re-torque the spring clips.
At the front, measure the frame height from the bottom of the frame flange to the floor. Take this measurement from behind the front bumper.
A / inch or less difference in frame height between the left- and right-hand sides of the chassis is acceptable. A difference greater than / inch indicates the need to replace the existing spring spacer blocks.
Chassis are built with both equal and unequal spring spacer blocks. When correcting chassis lean, select the appropriate spacer. Use a spacer with the smallest dimension necessary to correct the lean.
