richp Posted July 5, 2008 Posted July 5, 2008 I know Powermax rear pto shafts are very rare, and I'm not willing to pay $400 + for one. My question is has anyone thought of building their own? I have a clutch that came off the front that I don't need and was told they are the same. I was thinking either using small u joint on one end or even a driveshaft from a 7000 series I have kicking around in the garage. I have welded up driveshafts in the past with no problems so that part can be done. Any ideas?
D-17_Dave Posted July 5, 2008 Posted July 5, 2008 Using a hollow tube is lighter and stronger than a solid shaft and is easier to balance and align. The reason there is no joint in the OEM shafts is the shaft is aligned and centered off the engine. I think your problem will be the connection at the engine pulley. This MUST be near perfect or a lot of noise and vibration will result.
wilm169 Posted July 5, 2008 Posted July 5, 2008 The tube they use is the same as a jeep front drive shaft, If you can come up with the spline end, then you could make the other end on a lathe. The size of the bearing inside is 40mm and presses on, and is bolted from the back side.
tmerideth Posted July 5, 2008 Posted July 5, 2008 I also have pondered this issue. I have a 4040 that does not have the Pto Shaft. Could a hydraulic motor with a diverter valve be used to power the PTO?
4xbill Posted July 5, 2008 Posted July 5, 2008 Change your mind on the sale?? Didn't you have that beauty listed on ebay?
richp Posted July 6, 2008 Author Posted July 6, 2008 Yea, I had a line on a nice Ford 8n with loader, but the tractor sold before I could sell my powermax. Even though I always wanted an N series, I hated to part with the Max so soon. In a way I'm happy it didn't work out. As far as the shaft, I think the hardest part will be the hub that goes between the clutch and the splined input shaft. I've never machines inside splines before.
