I have a clunk in my right rear wheel I am hoping it is a bearing but according to the manual I have to pull the hub which involves a nut that I have never seen before. My question is what is the size and name of that nut and where can I find one. I am guessing I will be needing one sooner or later. I have attached a pic of the wheel to show exactly what I am trying to explain.

Its probably not what you want to hear, but looks like that nut is just a double flat. You can get it with a large open end wrench, after taking the weight off and the 4 eccentric clamps, and the rim... Never seen a socket made for a double flat, but that's just my experience ... ------------- Source: Babylon Bee. Sponsored by BRAWNDO, its got what you need! |

hmm, any chance one of the wheel weight nuts is a little loose ? I have 3 D-14 centers with cracks from the weight mtg holes. I assume POs had weights and never checked thier nuts...

| Jay brings up a good point, could be a loose wheel weight. Take the weight off and drive the tractor around to see if thats it, if you need to go deeper the weight needs to come off anyway. If the nut was loose and the splines bad I would think there would be final drive oil showing around the nut. |

The first thing I would do, is jack it up and see what wiggles. ------------- Looking at the past to see the future. '53 WD, '53 WD45, WD snap coupler field cultivator, #53 plow,'53 HD5B dozer Duct tape.... Can't fix stupidity. But will muffle the sound of it! |

This is a good possibility because I noticed the wheel weight has slotted mounting holes and the weight is off center. I will check thank you for your help |

If the rim clamps are wore, they will start to slip and make a clunking noise too. I would remove the weight, jack it up and see if you can wiggle things around to check for anything loose. The wheel center also fits on a tapered spline, and they can get wore enough to let things clunk. That might be a little tougher fix, as the shoulder would have to be cut back a bit, to let the wheel center go on further. ------------- 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 |

Take the wheel weight off, then use this: https://www.ebay.com/i/264138636087?chn=ps&norover=1&mkevt=1&mkrid=711-117182-37290-0&mkcid=2&itemid=264138636087&targetid=475515040781&device=c&mktype=pla&googleloc=9016190&poi=&campaignid=6469750693&mkgroupid=79220282802&rlsatarget=aud-622524042478:pla-475515040781&abcId=1141176&merchantid=114734071&gclid=Cj0KCQiAt_PuBRDcARIsAMNlBdqm_LrwO5kvS-vRTFpoeX77wi30b47-6Vcogby7AsH16AaCmo8wQ-4aAr-KEALw_wcB" rel="nofollow - https://www.ebay.com/i/264138636087?chn=ps&norover=1&mkevt=1&mkrid=711-117182-37290-0&mkcid=2&itemid=264138636087&targetid=475515040781&device=c&mktype=pla&googleloc=9016190&poi=&campaignid=6469750693&mkgroupid=79220282802&rlsatarget=aud-622524042478:pla-475515040781&abcId=1141176&merchantid=114734071&gclid=Cj0KCQiAt_PuBRDcARIsAMNlBdqm_LrwO5kvS-vRTFpoeX77wi30b47-6Vcogby7AsH16AaCmo8wQ-4aAr-KEALw_wcB  ------------- 1951 B |

| Those hubs are cast and the axles has a coarse tapered spline. I have seen many of the hubs that have been run loose and they begin to clunk as the hub wears untill the splines finally strip. They can be fixed if the splines are at least half there by cutting tapered shims and putting them in between the splines and really hammering the nut tight. Sometimes the hole is too big in the hub and it wont seat right so the back of the hub needs to be ground down to let it go on the axle farther instead of bottoming out. I have fixed many of these successfully. The nut is a standard thread so a regular hex nut can be put on there to really get it tight with a big socket. |

AS the guys said, it is normal for the splines behind the nut to wear somewhat, then the HUB will chuck back and forth a little on the shaft. Take the weight off and then jack up as they said and try to wiggle / push the tire toward the seat and back... You will see the SLOP either in the center nut/ spline or in the 4 rim mounting bolts..... I have a 30 inch cresent wrench I bought a Harbor Freight that I use on the nut and stand on the end.. Suppose to be about 500 ft pounds or so of torque... as hyperpack said, if the nut is TIGHT and the hub is LOOSE, then you take off the HUB and grind 1/8 inch off the backside LIP so the hub will slide on further.. I have done that.. I do NOT put shims inside the splines.... And I have also replace the nut with a standard HEX nut.. I think it is 2 inch by 12 threads per inch, but you need to verify that. ------------- Like them all, but love the "B"s. |

| Thanks to everyone. I am hoping tomorrow I can get the wheel weights off and rims and then see if I still got the wiggle. If so then I will look at getting the big frickn nut off and check the splines. I am still wondering if this can be a bearing. |

Well I got the wheel and the wheel weight off and come to find the hub still had a wiggle in it. as it turns out the big D nut was loose on the hub so all I had to do was just tighten it and no more wiggle. Spun the hub and everything seems fine so I will assume the clunk was the hub/spline being loose. I think I will go with a hex nut so it will be easier to tight in the future with the wheel weights on. Thanks to everyone for your help with this.
