 Topic: D-17 IV Shuttle?
Posted: 01 Feb 2025 at 5:10pm |
|
Quick questions for the experts. I have a D17-IV GAS, that I am going to have to split to do some power Director repair. I use the tractor as a loader tractor & for constant back & forth with a rotary mower in a Silvio pasture system. The constant shifting from forward to revers with the pto running is time consuming.
1). Can I change the power Director out and put a shuttle in its place?
2). If so, what’s involved in the swap?
3). If this is doable, does anyone know where I could get a complete shuttle that’s ready to go?
Thanks a lot! Any information will be appreciated.

This is of no help other than I have a neighbor with 2 170s with shuttle. Would think they are close to the same thing.

It is certainly doable, but you'd have to locate a donor tractor to remove and transfer all the internal gears, shafts and bearings from the area directly underneath your instrument panel. The lift arm housing on the back must be converted to a dual-speed PTO on any that I have seen. Lots of work and expense. You should try an overrunning clutch on the PTO for direction changing while using the PTO.

I use an overrunning clutch on the PTO of my series IV with the mower. Works great. Shifts quickly. Strongly recommend one. Far cheaper and easier than a shuttle swap.

The D17 chasis that were built to be cotton pickers had the shuttle as they were run backwards most of the time

Are you sure about that?? I don't know, but I'd have assumed they just flipped the ring gear/differential to the left side instead of the right side. This would maintain 8-speeds with live-power and no need for an oil cooler on the shuttle clutch housing.

Are there different overrunning clutches for different horse power ratings?

I've owned a couple of those over the years and sold them for people to build a loader tractor.Lever worked pretty much like the ones on industrial AC tractors.

So, to be clear, a cotton picker tractor only had 4-speeds forward and 4-speeds reverse ?? because it was a shuttle clutch ??

I've got advertising literature for the 616 and 622 cotton pickers. They both use a reversed D-17 chassis to carry them thru the field. It clearly states that it is a Power Director clutch in the torque tube. The tractors chassis harvests going backwards, so they have flipped the ring gear/differential over so it has 8-reverse and 2-forward if it was a farm tractor. Not a shuttle clutch. Harvesting was done in low gear in both LOW and HIGH ranges on the Power Director clutch.

I'm just repeating what the dealer told me in NC where one of them came from,he was pretty well versed on them for sure.One I had definitely had a reverser.

The AC D17 Industrial had a 4 speed shuttle clutch. There are a few around with loader and backhoes on them. ~ Orangeman

I can confirm Dr. Allis is spot on here. We have twenty some odd complete Allis Cotton Pickers and close to that number in cotton picker parts chassis. The ring gear is flipped to the opposite side from the regular tractor configuration and the power director works just the same as the tractor.
I have never seen a shuttle clutch in an Allis Picker. I have looked through the sales brochure and parts manuals and there is no mention of the shuttle clutch as an option. In my opinion having 4 reverse gears would not have been useful. When you're picking you spend as little time as possible backing up and stage everything where you're just making loops to minimize the time spent maneuvering.
Come to think of it, a 4th gear in reverse would sure unload that basket fast! The cotton just might not be in the ideal location when it does!

According to A-C's own advertising literature, there were two harvesting speeds: 1st gear on the LOW side of the Power Director clutch, and 1st gear on the HIGH side of the Power Director clutch. Everything else would be too fast for harvesting. A Shuttle Clutch would have left you with 1st gear on the HIGH side and no gear/speed slower than that.

That is correct. I remember my grandfather telling me that typically they would run in low and first gear on the first picking and then first and high on the second picking. The four cylinder units just didn't have enough power to pick a heavy crop in high range.
