So of course the rail holes are not drilled correctly on my new WD rims as I've heard happens a lot, they are Titan rims. Too close together so cannot line up the rim stop on the other side of eccentric. Just wondering if I can get by with one rim stop on each rail with eccentrics pushing against them in forward motion? If I were to go in reverse would they really move much especially not pulling any load? Eventually I will probably have to fashion a bolt with bevel washer to put on other side but it still won't look great. ------------- 1951 WD #78283, 1918 Case 28x50 Thresher #76738, Case Centennial B 2x16 Plow |

The wheel stops are meant only to stop the wheel at whatever point you want to set the wheel width when using power to adjust it. Although it might seem logical that there should be a stop on each side of one of the eccentrics to keep the wheel from spinning on the rail, that is not the case and as you have discovered, the holes aren't positioned to allow this. In reality, the friction of the little eccentric blocks against the rail is what keeps the wheel from spinning on the rail. Having said this, sometimes after many years, the rails may wear and there will be some movement of the eccentrics on the rail which will result in an annoying chuck when changing direction under heavy load. |

Well I was hoping that might be the case given how tight the eccentrics are but I've also heard the blocks can stop any slippage on the rails under extreme pulling or wearing over time. I won't worry about it with the new rims and eccentric blocks. ------------- 1951 WD #78283, 1918 Case 28x50 Thresher #76738, Case Centennial B 2x16 Plow |

| Must have both stops in place. Not that hard to drill proper holes. |

I would still put one on the reverse side even if you have to skip one hole, just for safety . ------------- 1945 C, 1949 WF and WD, 1981 185, 1982 8030, unknown D14(nonrunner) |

Dad farmed for 40 years with the CA and never had more than 2 wheel stops on it, one set narrow for plowing and one on the outside for cultivating. They shouldn't have to do anything once the eccentrics are locked or your locks aren't working right. ------------- http://www.ae-ta.com" rel="nofollow - http://www.ae-ta.com Lena 1935 WC12xxx, Willie 1951 CA6xx Dad bought new, 1954WD45 PS, 1960 D17 NF |

If the bolts are tight, you don't NEED any. Also stop and re-tighten, if you hear a wheel squeaking or creaking... ------------- Source: Babylon Bee. Sponsored by BRAWNDO, its got what you need! |

| Pretty simple to drill out the holes if need be, but id say its just over looking something |

| My Dad always had one on each side of the tightening bolt on the rail. I bought a set of power adjust rims for my D17 and could only put one on the rail. I called the vender on this forum I purchased them from and asked about it and he was very irritated and really hinted that I was stupid for asking. My old rims had 2 on each rail. They worked with one but I never used it on any heavy loads. I also never used that vender again. I went to others on this forum after that. The only time in the last 8 years I was treated like that by anyone on this forum ! |

They make a skinnier version of the stops that I use when needed. ------------- ALLIS EXPRESS! This year: |

D17JIM2, I stand corrected. I went out to check the wheels on both the WD and D-17 and you are absolutely correct; there is a stop on either side of the eccentric.I spoke from memory rather than actually confirming my facts.
As I remembered tho, the stops do not fit up to the eccentric tight enough to prevent it from moving 3/8 of an inch or so. So....if Bill_Mn cannot bolt a stop on either side of his eccentric, it would appear that his wheel may indeed be drilled wrong. The "chuck" I had in the old WD wheel was because the wheel had apparently been used almost exclusively at one width setting and the rails had been worn at those points over the years so that the eccentrics chucked back and forth that 3/8" or so whenever I changed direction under a heavy load. I remember now I was toying with the idea of making up some type of adjusting set screw to keep the stop tight against the eccentric but instead, I inserted 4 spacers about 1/32" thick between the eccentric blocks and the rails. That sorta worked but after a while they worked their way out and I decided to set the width differently to get back on the unworn part of the rail. Sorry about the misinformation. |

Well I'm going without a stop on the other side of the eccentric, the clamps should be able to hold position especially considering rims and blocks are new. If I have an issue with the rim moving will have to figure something out. I don't quite understand what the function of the clamps would be if you also needed those stops to keep the wheel in position anyway? ------------- 1951 WD #78283, 1918 Case 28x50 Thresher #76738, Case Centennial B 2x16 Plow |

I saw a tractor pull where there was no stop used, when the wheel decided to slip on the rail it went all the way to the end. If it is going out may not hurt but if going in could get your fender. The man in this case stopped right away as he thought he had broke the rear end of the tractor. ------------- 1945 C, 1949 WF and WD, 1981 185, 1982 8030, unknown D14(nonrunner) |

Like eldon said there is different width stops our 17 we ran one Narrow and one wider to keep them close ------------- You can wash the dirt off the body but you can’t wash the farmer out of the heart and soul |

I put the plow on my WD once and started plowing not knowing the stop was not on the wheel. I hit a tough spot and the tractor slowed as the LH wheel spun all the way out, front end came off the ground and away I went! Startled me until I figured out what had happened LOL! ------------- ALLIS EXPRESS! This year: |
