View of the space between the cat walk and the enclosure
With the machine on level ground, record the distance from the enclosure to the edge of the walkway (A).Note: Make sure that the implements are raised so that the machine weight is fully on the tires.
Raise the back of the machine into the air. Using the same reference points on the enclosure and the walkway, record dimension (B).
Subtract the value found in Step 1 from the value found in Step 2, and record the difference. The difference is the tandem sag measurement.
If the tandem sag measurement reaches 7 mm (0.28 inch) or more on the 14M and 10 mm (0.39 inch) or more on the 16M, then schedule an immediate rebuild to prevent square or top hat housing damage.
Repeat this process on the other side of the machine.
