Hi, I have been helping a friend out with his 318 rear pto. He hit somthing with mower deck and broke the rear output on the box. (it was already missing about 1/4) we figured out a work around for the out put.
Our real problem is on the input side. The pto was bought used and had been rigged sometime in the past.
The bolt that holds the clutch plate to the pto input shaft had been welded. I found a new input shaft on ebay that is a 17 spline 3/4 input.
Didn't realize till much research online that Deere did a design change and went from the splined input to a tapered shaft, with the adapter held on by a bolt! ( I originally thought the shaft slipped and stripped off the splines)
The clutch adapter is still available from Deere but the shaft is not.
I welcome any help.
Thanks Steve

There is a shaft that runs from the rear of the hydro pump to the electric clutch. It is essentially the same on three of the systems that I am familiar with. The drive coming out of the clutch had three different designs based on what was being attached.

If a 2000 RPM gearbox was being attached then a tapered drive plate was attached to the rear of the gearbox input shaft and attached with a bolt. Then that plate was attached to the electric clutch with four bolts
Pinion in the gearbox is M71724
Plate attaching to electric clutch is AM103498.

If a rear hydraulic driven tiller was being used then the pump had a double drive pulley which was driven by a shaft with a double pulley also. The top shaft was welded to a plate which was then attached to the PTO with four bolts.
The plate attaching to the electric clutch is AM102325. Mostly used by the 400 series
(420, 430)

If a material collection system was being used, it only used one v-belt. the top shaft or the drive pulley was held in position by a bracket attached to the rear of the differential. This shaft was splined on the input end and loosely fit into the splined plate attached to the rear of the electric clutch.
The splined shaft is M86518. The plate attached to the electric clutch is AM39490.

Don't know if any of this helps as I am having some difficulty with some of your description so I am just giving a general description. Can you post any pictures?

John Deere did make changes

Thanks Doug, Yes it is a 2000 rpm gearbox that was running a 260 rear finish mower.From what we can determine is the early gearboxes used the same 17 spline size as the hydrostat. Later they switched to the tapered shaft and bolt setup. Im having difficulty loading pictures from my tablet. Thanks Steve

A ******* fix would be to weld the plate to the shaft coming out of the gear box. That means to separate them, you would have to unbolt at the clutch (four bolts).

The proper way would be to replace the two parts, the shalt and the plate. There is a gentlemen on the site that has changed these gear boxes to run 540. He might have the spare parts. Do a search for this. Conversion from 2000 to 540.

I think the gentleman might be David Thewes but I'm not sure. He might be able to connect you with others.

Steve Phillips -

Call me with your needs , I can most certainly help (I think) . I have a few Peerless 2800 (gear-box) input shafts and flanges . I have one very interesting set up from the Simplicity version Peerless 2800 (spec. 003) gearbox that has the splined input shaft with a right hand threaded hole and bolt to keep the splined flange interface together without wobbling and wear as experienced with the original J-D (spec. 001) . The new revised input gear , Peerless spec. 002(taper-lock end) was still available from Deere a couple years ago , but at approx. $175.00 , plus the new flange interface to go with it, at approx. $120.00 , puts you at 300 bucks , plus tax and or shipping , depending on source .

I will do you right on these (new , never used) parts , should you decide to contact me .
