SWEEP CYLINDER REPLACEMENT
1) Park the unit on a level surface with the tailgate shut. Bring the swing and sweep panels to
the retracted position. Remove the keys from the ignition, use proper lock-out/ tag-out
procedures, and chock the tires. Finally, disconnect the negative battery cable.
2) Reduce the hydraulic pressure in the system by operating the hydraulic valve on the tailgate
and body until all the hoses are limp.
3) Disconnect the hoses going to the sweep cylinder you intend to remove. Ensure all hoses
are capped and plugged; and the cylinder is plugged to prevent contamination.
4) Disconnect the sweep cylinder from the sweep panel rst by removing the bolt, nut, and
lock washer. Then slide the cylinder pin inward to remove it.
5) Disconnect the sweep cylinder from the swing panel by removing the bolt, nut, and lock
washer. Then slide the cylinder pin inward to remove it.
6) The sweep cylinder should now be loose. Remove the sweep cylinder from the tailgate,
drain the hydraulic uid, and plug the cylinder.
7) For installation, simply perform the above procedures in reverse order. Apply a liberal
coating of anti-seize compound to all pins before installation.
Never disconnect a hydraulic hose or tube containing
pressure. Pressures in this hydraulic system are high enough
to cause serious injury or death. Hoses may whip or hydraulic oil may burn skin, or cause eye damage.
Use extreme caution when working with the hydraulic system.
The sweep cylinder is heavy. Use caution when removing.
