Hello, 1961 D15, I really need help identifying the partial round ring in the pic. I removed the side cover and found this inside the torque tube. I've looked at the shop repair manual, looked online for a description and see nothing about this ring/spacer/shim? What is it, where does it go, and how do I get a replacement? I need to know more about this before I split the tractor. I have a replacement brass collar and PD shifter fork.

| You're going to have to split it anyway. Is it round wire??? or flat like a snap ring?? I cannot think of anything in that area that is bigger diameter than the shifter for the brass collar. |

| Hello, neither a wire nor snap ring. It's flat like a shim or a spacer. I can see by the blue RTV that someone has had this split for whatever reason. Have you seen anything like this in the PD clutch itself? |

| Looks like a case of "someone who didn't know what they were doing " worked on it. |

| I think once this Power Director clutch is out on a work bench, it needs a complete disassembly and the eyes of an experienced person to look at it. I have a feeling the shim stacks are waaaay off and who knows what else is wrong with it. I'll bet the ramp plates pockets are on the verge of jump out when at full throttle too. |

Think that is the end of the power director clutch hub broke off... ------------- When told "it's not the money,it's the principle", remember, it's always the money.. |

Correct me if I'm wrong, but it seems like there is a particular direction that the brass piece needs to be assembled relative to it working with the shifter fork? ------------- 1950 WD, 1966 D-10 III, 1961 D-10 II, 1966 D-15 II Gas, A-C Minibike, 917 Hydro Mower, 917 Hydro Blower w/cab, West Michigan "Allis Express" |

| Good thought, if there is I need to know. |

| The brass collar has a thick (rear) side and a thin (front) side. It will be obvious which way it goes when you assemble it. |

| Yes, I found one brass collar pin broken off and a piece from the collar fork broken off. |

That almost circular steel flat ring looks to be what is left of the square ridge that the brass shifter clamps around on the clutch shifter. Once the square ridge wears down very thin, and thus weak, it will break off the clutch shifter. I've only seen this once on a parts tractor, usually the brass shifter wears out first, but who's to say that hasn't been replaced once before? ------------- www.awtractor.com A&W TRACTOR 920-598-1287 KEEPING ALLIS-CHALMERS IN THE FIELDS THROUGH THE 21ST CENTURY |

| Thanks for your opinion! I have a parts book and a repair/shop manual and looking at pics online but not sure I can see what you're referring too. What was square but now worn round? So, this may have been where the fork contacts the brass collar? |

| On second thought the fork only contacts the brass collar pins/dogs |
