B-10 Drive coupler

Recommended Posts

My B-10 seems to be short of rag joints when I went to install the drive shaft. I have a set of the nylon discs but that leaves me with almost three quarters of an inch short. I am not sure of using washers to make up the differance. Anyone found a good solution for this problem?

can you loosen up the set screws at the BGB end of the drive shaft and slide the yoke, and therefore the drive shaft, forward the 3/4 inch? hope that is the solution as i am near putting the 12hp on the parts machine but will not be putting in the hydro pulley.

I was looking to do that on my squire but it leaves very little shaft inside the yoke, I changed my mind and put the hydro pulley on it and will be using that pulley to run the pump for the FEL.

You can use washers to make up the difference. I would not move the rear yoke that far forward, because of the added load (leverage) that will be on the BGB bearing with the yoke out near the end of the shaft. I have one tractor with a stack of washers on each bolt. I have another with tubes for spacers. Since I didn't have the factory flywheel spacers, I made my own. I also put the fiberglass disks in my 61 Wards (Simplicity 700). That one has the spacers made from tubing. You should definitely loosen the set screw on the rear yoke and let it float on the shaft till the driveshaft is bolted solid in the front. You do not want to put tension on the flex disks along the direction of the driveshaft. That can cause a premature failure.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time
