MD-24 System Applications
Typical MD-24 Installations:
The MD-24 control system is easily adaptable for single, dual and even
triple station installations with single or twin gasoline or diesel engines
with hydraulic reverse gears. The following examples are but a few of
the many adaptations possible.
Multiple Stations
An MD-24 system can have several control stations simply by con-
necting all the stations to a common jack shaft and running one cable-
over-pulley system to each engine as shown above. In most cases,
standard Morse chain and sprocket assemblies may be used. Shafts,
pillow blocks, etc., should be obtained locally.
Two Lever with Omega Reverse Gear
MD-24 is set-up as a two lever control system with the Twin Disc
Omega reverse gear. Note a standard single function control such as
the SR can be substituted for the throttle utilitzing a Red-Jaket push-
pull cable.
Twin Engines
Twin engines can be easily controlled with one hand when using a
Morse heavy duty system.
