Why would you want to delete the dual power.

There is one, my 9000 had one in it when I got it. You will have to search salvage yards. I have to ask also, why? They are not that difficult or expensive to repair.

Basically... you would need the front cover and input shaft and all related parts for the 8 speed. As far as I know, from the transmission housing back is identical. Just the front parts need changed.
Why you would want to do that is a better question........... Dual power units were pretty solid as long as you keep the pressure to them. Replate and reseal them once in a lifetime... and modulate your use of the throttle a bit when you shift.

If 5000 transmission parts are the same I'll tear my 5000 apart and trade with you as long as the dual power is rebuildable.

The biggest issue with the original Dual Power units was the steel seal rings that they used - it would wear grooves in the main housing where the direct clutch spun. Fortunately, they made that wear surface replaceable, and I believe you can still buy that wear sleeve from NH.

I would also be inclined to repair rather than delete it. If you've ever used a functional one, you'll really miss it when it's gone.

I put a new sleeve in mine maybe five years ago. The original was worn very little when I first got it and put it in my 9000. After replacing the cast iron rings with plastic ones it wore deep grooves in the sleeve in some ten years of fifty shifts a year. I'll be looking for some open stock cast iron replacements for them rather than put plastic in again.

That makes no sense to me, as I've had the exact opposite experience. In fact, after Ford went to the plastic style seal rings, they eliminated the sleeve.

A line of machines that I used to work on had a part with a bronze bushing riding against a stainless thrust washer. The washers never wore out. Then they changed to a delrin bearing against the same stainless. The derin would pick up all kinds of little abrasive particles which would imbed and be held in the delrin. Thus it became an abrasive wheel and would wear right into the stainless.

cheaper repair when using used parts ....one less thing to worry about keeping repaired and working on a 40 + yr old tractor ..

Where are you located, I may be interested in trading you the front section of my trans for your dual power stuff.
