If needs be can get it turned wider but hoping to do this more-or-less on the cheap and I don't have lathe/access to one other than commercial machine shops in town. -- |

Center up the bearing on the precise part? |

Well, mayhaps I can...was thinking only about a continuation of mating surface but as you note if can get the collar over and the bearing on the clean surface that should work. I'll have to clean up the other end enough to fit a bearing--it was just on the PTO shaft before w/ the large casting holding the vertical load whereas now I'll have to support that load w/ a bearing. But, it's 12" long or so whereas the other end has a 2" OD portion of the driving roller that fits against the shoulder of the bearing surface and that must be where it goes--the shaft is too short for there to be enough length for the key otherwise. -- |

Can't you just use a standard PTO shaft, and bore and pin one end to match the drive on your mixer. I have three implements that use a PTO, and I have a PTO drive shaft I leave on each one. They were not particularly expensive. |

I have three implements that use a PTO, and I have a PTO drive shaft I leave on each one. They were not particularly expensive. Yeah, what you're missing is that this is a solid PTO shaft extension and the mixer drum is friction-driven by resting a tire on the roller (outboard) end of this extension, not a direct drive. That eliminates all gearing that would otherwise be necessary to let the drum tip for dumping. Originally this shaft was supported by the large casting w/ the inboard end (driven end) supported by a matching ring that fit against the rear housing around the tractor PTO to keep the load off the PTO shaft but there's not enough clearance for that. So, I need a way to support the drive shaft w/o the former casting. Unfortunately, I don't have current pictures; best I've found on web is at http://www.ntractorclub.com/manuals/misc/ /implementsTransmix%20Utility%20Mixer%20-%20Dealer%20Ad%20Brochure%20- %20Other%20Mfg%27s.pdf The picture from the rear on an International 300 is best view of way it was mounted on the Farmall 2-pt "quick-tach" -- the Farmall (looks like an old "M", maybe, in the picture?) isn't quite the same altho we had it on the 560; it was later "styled" w/ the squared-up front grill and the 2-pt. That one appears to be w/ external hydraulic cylinders attached on to the swinging drawbar support as near as I can tell. -- |

Actually, you can visualize pretty well the problem from the "numbered selling points" diagram/picture at top of second page in the brochure. Pt 8 highlights the PTO extension and altho it's a little tough to see 'cuz they left a white square in the image between the 6 and the 8 you can just make out the open end of the drive hub on the end of the shaft by the dark shadow. At that point that #6 is a tire mounted on a rim welded to the bottom end of the drum and it rests on that outboard end of the shaft. The shaft is supported originally by a solidly-mounted casting w/ a bearing at the outboard end for load support there and the casting mounting was adapted to the particular tractor such that it carried the load at the drive end to avoid transferring the drum load to the tractor PTO bearing. Since I can't use the casting on present tractor(s), I'll have to construct a replacement structure for it and mount it on drawbar hanger and whatever else works out to be convenient attachment point. I'm thinking rather than try to make such a heavy mount and rely totally on the one rear bearing I'll just add a support bearing at both ends of the shaft on my new support. One I've got this, then I'll have final dimensions from which to work to adapt the cradle from the 2-pt arrangement to use the 3-pt arms and then it looks like can use the rollbar mounting brackets for the upper supports w/o too much effort--turns out they're in at least same ballpark of the same width as the existing axle support mounts and roughly same height. -- |

I think I can get the shaft turned for that, roughly, probably, and go w/ a standard pillow block. If could get the inch ID on the bearing I'd consider it, but when still have to either shim or pare down the shaft anyway, then it just doesn't seem any real strong advantage. But, as another noted, it is surely a resource to add to the save links...and thanks for that and the suggestion. -- |

And, the support arrangement I need is essentially the same as that so there's no real difference there. But, yes, I did ask for any other ideas, so thanks... ![]() -- |

The PTO support casting for it is very evident in the pictures--quite a bit smaller than the one for the Farmall 560 I have. That one and manual are pretty widespread--I found it at several locations on the web. -- |
