Ariens Company has discovered that push nuts used in the manufacture of air ride seats p/n 04383700 may
not have been properly seated. In some cases, improperly seated push nuts have come off, allowing control
arms attached to the air-spring saddle to come loose leading to the saddle bending and damaging the air­spring bellows.

Dealers are to inspect all unsold inventory in the model and serial number range listed above and correct if
necessary.

1. Check the Milsco serial number of the seat on an affected unit. If the serial number of the seat is
above 53-798950 then it is not necessary to do any further inspection.

Remove two
1/4” bolts.

Left Push Nut

Right Push Nuts

Lip on shaft (push
nut removed).

2. If the Milsco serial number is 53-798950 or below, remove the lower seat cushion. Remove two ¼-20
bolts under the front of the cushion. Pull cushion up and forward to remove.

3. Inspect the three push nuts holding the arms to the air-spring saddle. One is found on the left side
and two are on the right side.

4. If the push nuts are not seated properly, use a forked pry bar or screw driver to push the nut into the
correct position.

5. Properly seated, the push nut will be pressed against the lip on the shaft. The following photograph
shows the lip with the push nut removed.

If a damaged air-spring bellows or saddle is found, the saddle assembly can be replaced using Air Spring
and Saddle Kit p/n 59212300.

Standard warranty applies. Dealers will be reimbursed .25 hour for each seat inspected by removing the
cushion. For more information, contact Gravely Technical Service at [phone].
