Figure 2. Tailgate Components: M917A1 and M917A2 with MCS.
The MCS tailgate has four openings (gates) that are electropneumatically controlled by a cab control unit or a
handheld remote control. Each gate can be opened and closed independently of the other gates.
Compressed air, plumbed from the chassis's air system and stored in an air reservoir mounted on the MCS
tailgate, opens and closes the gates using solenoid-controlled air cylinders.
Gate opening adjustments are made at each gate, using an adjustment tube with a locking pin that can be moved
to different holes in the tube. The lower the pin placement, the larger the gate opening. The top pin placement
locks the gate closed.
The remote control has a coiled cable that plugs into a receptacle on the driver's or passenger's side of the MCS
tailgate. It is operated by a person walking alongside the dump body, while the operator inside the cab is dumping
the load. When plugged in, the remote control overrides the control unit inside the cab.
The MCS tailgate can also operate as a conventional tailgate, opening from the bottom.
