I was just wondering, what is inside the D17 seriesIV that runs the hyd. pump? I've never been in one and was wondering how big a job it would be hanging one on an older 17. I know what the end of the belt pulley looks like but wasn't sure how they drove the hyd. pumps. Just brain storming.

I have one on my d19. Works good but it stops when you push in the clutch.

D17 Series IV has a hollow quill shaft driven off the front side of the clutch (flywheel?)/ on the engine side running back through the torque tube with a 90 degree shaft to run the pump on the side. Inside the quill shaft driven off the back side of the clutch is the main shaft running to the power director. So when you press the foot clutch the shaft to the PD stops as it's on the back side of the clutch but quill shaft driven off the front side of the clutch keeps spinning giving independent hydraulics.
I'm sure someone will be along to correct the specifics of my explanation above.

The hollow shaft that runs the hydraulic pump is splined into the pressure plate/spring holder side of the clutch assembly which was bolted to the flywheel, so it always turned when engine was running. IHC did the same thing for live PTO on the Super MTA and others; Oliver did it with the Super 55, and probably others used this method as well.

tramway is right it runs off the pressure plate but the d10 and 12s series 2 and 3 ran off the flywheel

Thanks, we've had a few series I's and II's but never seen the inside of a series IV, just wondered how big of a deal it would be to give an old 17 newer hydraulics.

I am going to venture a guess that the torque tube would be different as the hole must be bigger to accomidate the hollow drive shaft and so you would need at least a pressure plate ,torque tube(or be able to machine it out ) hollow shaft, pump drive, pump, and shaft from from a series 4 or early 170, at a minimum, not counting the hyd lines and a valve bopdy, but it could possibly could be done, was at a sale last year where a series 4 sc tractor brought 6 or 700 bucks, (all taken apart and several things missing like 3/4 of the engine and sheet metal and such) may be feasable if you could find a junk series 4 like that

It wouldn't be as pretty or anywhere near stock but mounting a pump on the front pully would do the job and not cost a fortune.

The clutch shaft thru the torque housing is different on a Series 4, which would require a double split for access getting one out and then installing it in an older D-17. There may be a small difference at the attachment point on the side of the torque housing, but I don't remember for sure. In the end, it probably could be done, but a front crank driven pump is easier. Just build a guard around it for protection and style.

I got the same problem. After seeing DickL cut that torque tube, I been having dreams of a WD with a power director.
