Cummins and ZF

Post by Mikey »

O. K. Gang, here's the deal.
I'm ready to hook up the transmission controls to the ZF's but don't know which way is forward and which reverse. One kibbitser says starboard is different from port but didnt know which was which. Uncle Vic, our rigs are the same so, next time you're on A.J. would you verify which way is which?
Tanks, Spanky.

One gear will run in reverse, to accomplish counter rotating props. Its too late at night for me to remember which, but one way to check is to crank the engines and manually work the lever on the gears, assuming props are on shafts and the boat is in the water. The boat will move forward or back in opposing positions, hook up the cables from the levers accordingly. You change them by changing which side of the gear the cable pulls/pushes from. Poor, stupid , man's technique.

Kevin,
Do Steyrs turn the same direction as Cummins? Is that a dumb question?

To my knowledge(which is not much) all motors diesel or gas are left hand runners unless specified counter rotating. Not sure if there are diesel counter rotating engines. When I had the chryslers the starboard motor was the counter rotating motor. From the behind the boat looking at the props the starboard prop should spin clockwise and the port would be counterclockwise...in forward gear of course. I would have got that PM to you sooner but the website gave me a mesage stating "you cannot post again so soon after posting a mesage" Never had that happen before.

Mikey, The Port lever goes down for foward gear. I switched the port shifter to the foward leg so both cables were routed over the top of the tranny.

If it is a ZF 220, I think that looking from the stern, the control lever moves to port for the same rotation as the engine and to starboard for oppisite rotation. You can check on ZF's web site as they have all their installation drawings on the web. Very good web site with lots of info.
