Hi, I tore apart a project CA and have a question. When I pulled the engine, the drive shaft (pardon me if that is not the actual name) came with it. I was able to remove the drive shaft from the engine side and it is back in the housing. The shaft spins freely in its housing even though there is a spline on the opposite side of the shaft which goes into the motor. Seems odd to me. Seems like there is some trick to getting that spline back to where it goes. Is that normal, or is there a trick to getting that spline to go back into where it belongs? I am about to put everything back together and don’t want to have to pull it apart again. Thanks. |

the B-C-CA had this "drive shaft" from the clutch to the transmission thru the Torque Tube.. Originally i think they had a roll pin to retain the shaft the to transmission so it would not pull out... later the roll pin was deleated and the shaft is just trapped between the trans and clutch.. Also there was a universal joint on some tractors, then eliminated later on...... If the trans is IN GEAR, then the drive shaft will not rotate... you should be able to look down the tube and see the trans splined shaft... maybe a rod to broom handle can be used to raise up the shaft as you push it in to get on ONTO the TRANS spline shaft..if not, you will have to remove the torque tube bolts and slide the tube forward 6 inches to get at the trans shaft.. look at the end of the drive shaft you are pushing in toward the transmission.. should be obvious that it is needing to fit over the trans shaft.... might take some effort to pry it up as you push it in..

| That makes complete sense . Before I posted, I put it in gear and the shaft still turned so I knew something wasn’t right. Your explanation makes sense. Thanks so much. |

Per the Allis Parts Catalog 1960: a picture shows the splined Clutch Shaft is attached to the splined Transmission Shaft with a splined Coupling / Sleeve. This splined Coupling / Sleeve is held on to the Trans Shaft with a Cotter Pin. See attached Picture by Dick L. G |

| Many thanks Sir. It came out fairly easy so hopefully it goes back in. |

Yes it should be fairly easy. The trick will be to support the end of the splined DriveShaft and get it lined up to slide into the splined Coupling. Put the Trans in Gear so that the Coupling stays rigid. Turn the Shaft until the Splines Line up. G |

if you can slide it back in without removing the torque tube, then you dont use the cotter pin to retain the shaft... I would still like to know who took all these tractor apart and removed the pin put it back together WITHOUT them !!  ------------- Like them all, but love the "B"s. |

Steve Like I said in my Post above - info from the Original Allis Parts Catalog. There is only one cotter pin, as I said, securing the splined coupling to the Trans. Shaft. Where are you getting the idea that a second cotter pin is required, or even used. Obviously you would attach the coupling with the Cotter Pin while the Torque Tube is removed. Do it by the Book and it's a piece of cake. G |

Update, I pushed the shaft all the way toward the transmission until it stopped. I then put downward pressure on the front of the spline forcing the rear of the shaft to tilt up toward the transmission while slowing spinning the shaft. Eventually, I found the shaft and sent it home. It was actually fairly easy once I knew what I was dealing with and came up with a plan. Thanks again! |
