Air Spring Adjustment
1. The air pressure delivered to the air springs is the
same for all openers. To be able to increase the down
pressure for specific row units such as in wheel track
locations, the air spring has two mounting positions.
The normal position is forward, with a heavier setting
by sliding the air spring to the rear. The heavier
setting will increase the down pressure by
approximately ten percent.

Relieve system air pressure before attempting to
adjust or service any air spring component.
Make sure all components are in place and
secure before charging the system.

AIR SPRING
2. To adjust the air spring location, first relieve the
system air pressure. Loosen, but do not remove the
3/4-16 hex jam nut at the top of the air spring and the
1/2-13 x 1 hex head cap screw below the air spring
and air spring pivot. Slide the air spring forward or
rearward to the desired location (See Figure 4-22.)
IMPORTANT
Make sure the air spring has fully reached the ends
of the top and bottom slots before retightening. If the
air spring is not in the ends of the slot, it will be out
of alignment and can rub internally wearing a hole.
Also, be sure the air spring is not twisted when
retightening the fasteners.
3. Retighten the top jam nut and bottom hex head cap
screw to secure the air spring. Recharge the system
with air to normal working pressure.
NOTE
Maximum torque on the top jam nut is 30 ft. lbs.
