My 1939 B is a crank start only model. I have no desire to change that, but it does bug me that the crank handle basically rubs up against the nose sheet metal Everytime it is cranked over. I was wondering if anyone has done anything to protect the metal and the finish? I have ordered a crank hole casting in brass that is originally for the model G and I am looking to fit it on to the B. What are your thoughts? Anyone done this or something similar?   ------------- 1939 AC Model B, 1952 AC Model G, Case 195, numerous Wheel Horse, Hit Miss Engines, currently looking for a AC B10 garden tractor |

| They came with a flat metal piece spot welded on the inside. Most of mine were wore thru by the time I bought the tractor. I like the idea of the G part being used. |

That looks like a great idea! Regards, Chris ------------- D17 1958 (NFE), WD45 1954 (NFE), WD 1952 (NFE), WD 1950 (WFE), Allis F-40 forklift, Allis CA, Allis D14, Ford Jubilee, Many IH Cub Cadets, 32 Ford Dump, 65 Comet. |

| Looks like a great idea. Make sure the crank for your B will fit thru it. |

| I, too, think it's a good idea. Mine is a little egged out from years of cranking. |

| I can get 1/2 in steel from work. I was going to cut out a plate to go on radiator mounting bracket to see if it help. That the problem on mine anyway that hole is worn way out oblong. |

Got the bushing in today, crank handle fits fine. Will have to open up the hole some on each side to fit the oblong shape of the casting. ------------- 1939 AC Model B, 1952 AC Model G, Case 195, numerous Wheel Horse, Hit Miss Engines, currently looking for a AC B10 garden tractor |

Today I opened up the crank opening on my Model B and fitted the brass Model G bushing to it. Fits pretty good, now need to cut s gasket to fit under it and find some mounting hardware. Think it's going to work pretty good. ------------- 1939 AC Model B, 1952 AC Model G, Case 195, numerous Wheel Horse, Hit Miss Engines, currently looking for a AC B10 garden tractor |

| Are you going to mount it on the outside or inside of the shell? |

Just what I was going to ask. You could rivet in place with the fitting on the inside and it'd hardly be noticeable. ------------- WC, CA, D14, WD45 |

Inside mounting poses another set of issues, one, the lip of the expanded metal would be in the way. Mounting without the flange covering the opening would also require a lot of rework of the opening and a refinish of the shell. Since I am not sure of the color yet (know the brand), I do not want to venture into a repaint till maybe this fall. If I can identify the color, then I am going to rework some additional area of the shell including replacement of the mesh, and at that time If I could find a damaged Model G tail section and cut out the stamped area, it could be grafted into the B shell to mount it as is mounted on the G. ------------- 1939 AC Model B, 1952 AC Model G, Case 195, numerous Wheel Horse, Hit Miss Engines, currently looking for a AC B10 garden tractor |

Paint it orange and it will only be noticed by those that claim to be correct police. When I was pulling and had to put the C in a line of show tractors to qualify for the pull I had a big time setting back and listen to the correct police wondering if Allis ever put a straight drawbar on a C. A picture for those that had not seen it posted before. One of a kind Lemmon drawbar set for pulling at 13 inches from the ground.

Finished up installing the Model G brass crank hole flange and the B is now all buttoned back up. Works great, no more rubbing off the crank handle against the grill sheet metal. While I had the tin work off, touched up the black paint on the engine components and manifold. Instead of webbing between the metal joints, I used a heavy gauge clear mylar tape that I have used on the tin work of garden tractors with good results. Is heavy enough and has enough lubricity to prevent chaffing. I did use a piece of orange webbing under the hood/tank body strap.   ------------- 1939 AC Model B, 1952 AC Model G, Case 195, numerous Wheel Horse, Hit Miss Engines, currently looking for a AC B10 garden tractor |

Seeing this, I'm thinking of getting one....any my B doesn't even have a crank pulley that allows for the use of a crank. ------------- 1951 B |
