Unusual Detroit 6046 6-71

[Perry Kitson]

Both engines crankshafts turn counterclockwise when standing in front looking at the fans. I think I only muddied the waters adding the talk about what the manuals say. Detroit Diesel always refers to rotation direction when looking at the engine from the flywheel end. The military refers to rotation direction from the fan end in the manuals. So the twin set up has both crankshafts turning the same direction, counterclockwise when observing from the fan end of the motors. The camshafts turn opposite direction because you are feeding the engines from opposing sides.
My Sexton uses the 9 cyl. radial.

Thankyou Perry for clarifying that.
Yes both engine cranks in the 6046 twin pack spin in the same direction.

Now back to my engine which spins the opposite way to the normal 6046 twins. Valentine maybe????

Anthony,

I'm pretty sure my 6046 army manual says that only the crossbox had the serial number for the 6046 power pack and that they didn't record the individual engine numbers. (Pretty odd idea that) So curious if your motor has the pictured plate affixed directly to it. Can you provide a more general view of the motor and include the plate in the frame?
Also a shot of the fan drive as that might clear up any Valentine possibility.

Hi Alex,
Here are some pics of the motor. The first one shows the whole motor with the two plates evident. The brass 6046 tag on the rear and the silver model tag behind the rear air filter. As I stated in the first post the 6046 tag is different to the usual 6046 tag on the crossbox as it does not list the reduction ratio.
The second pic of the front of the motor shows where the fan extension housing has been cut off and welded over. This motor was found on an abandonded irrigation pump. The exhaust has also been modified to facilitate an upward outlet. The water manifold is broken and is currently removed.
Cheers.

here is a picture from our twinset,as you can see the tagplate is mounted on the gearbox.
