One of the details still needed to be squared away to be able to drive the rusty redneck B off the trailer is to secure the right rear wheel back on. I'm missing the large nut that holds the splined joint together, am I correct in my measurement that it's 1 1/2"-12 fine thread? Thanks, Dan.

YES .................in the US... ANY BOLT bigger than 1-1/8 inch has a 12 thread per inch STANDARD Fine Thread..
just for information sake.. If you were working on a large steam turbine or 5000 HP electric motor that has 2 or 3 or 4 inch diameter bolts... they PROBABLY have 12 threads per inch..... Thats a STANDARD.. Makes it easier for Machinist to repair or make a shaft in a lathe since they are all the SAME.. ------------- Like them all, but love the "B"s. |

Too bad you're across the big pond, I have a lot of the parts that you've needed to resurrect the B you're working on. Shipping out of the US had always proved too much of a PIA to make it worth the trouble. ------------- If it was fun to pull in LOW gear, I could have a John Deere. Real pullers don't have speed limits. If you can't make it GO... make it SHINY |

the actual NUT was a SPECIAL PART made by ALLIS.......... but you can buy a HEX NUT that will fit.... Should be available at local Fastener Shop.....i have wondered why ALLIS didnt just buy HEX NUTS for the axle ? ------------- Like them all, but love the "B"s. |

Dan Your resourcefulness in getting this old B running is amazing, but it’s hard for a lot of us to watch your struggles knowing we have the parts you need. You never know how parts can make it across the pond. I took a CA gas tank in my suitcase to Australia a couple of years ago. That makes small things like nuts and distributors easy, just have to keep it under 50 pounds! Bill |

Yep, wish I were over there for more than just the parts availability. This country is a mess! Steve, thanks for the confirmation. I'm imagining Allis used the special nut maybe for slightly wider flats for the huge torque? Either way, should be able to get something locally that will suffice. Bill, I'm sure there's parts available over here too if I really wanted to pay the money for them. My struggles mainly are the result of my tight wallet & a desire to see a tractor that would otherwise be headed to scrap work again. (remember, the tins are very rotten & a good deal of heavy corrosion even to the iron parts, non-original rear wheels also rotten. TBH I feel like this was a yard scraper or otherwise working in slurry for a good deal of it's life) Rest assured though none of the hackery is irreversible & if I do want to make it right in future it's a simple case of unbolting my hacks and installing correct parts. The old girl is growing on me & even if I don't take her to the next level it ought to be a lot easier to find someone to take her on if I can demonstrate that the bones of the machine are sound. Honestly though, I am feeling like she may stick around a while

Personally i like to read your posts about the home made rocker shaft, Ford Distributor and who knows what for water pump... Everyone needs a little smile time in their life.. I get mine from YOU.... I have done a lot of MODS in my life time, but never to this extent.. I REALLY get a kick out of your resourcefullness !!
