Cutting new keyway on BGB shaft

[portuncia 0]

Well spring is almost around the corner and I will be planting my first garden ever now that I have the space for it. That means the tiller for the B-112 will get its first real use. My keyway on the shaft end of the BGB is pretty chewed. Some one here posted about cutting a new one with a cutting disk. I know you have to be pretty precise. My question is do you think a dremel tool and the cutting disks it uses would work? Any other ideas TIA Jeff

I would think it would be better to just swap out the whole BGB. I'm sure someone here has a few spares. It is possible to cut a new key way, but I would think that the time you spend grinding a new key way, you could swap out the BGB from start to finish.....well maybe not, but you get my point.:D

If the BGB is tight, I would grind the new keyway in. It may take time, but certainly would be less expensive

I had mine cut in at a machine shop for $20. But that was removed from the bgb.

I had mine cut at a machine shop for $20 as well, it was removed. It really needs to be a very tight fit to last.

Jeff, I have cut a couple keyways with a Dremmel and the cutoff disks. I usually put two or three together. Just take your time, and try the parts for fit real often. When I do the last trial fit, and it almost goes all the way where I want it, I usually drive it home to make a slight interference fit. That way there is not slop to allow it to wobble out again. Good Luck.

For $20.00 I would take it to a machine shop.

They make keys in different widths. You might try cleaning up the keyway and grinding down a wide key to make step down 2 sized key. If you wish to exsperiment a little on an extra shaft you can test your abiliaty and gain some experiance before you tackle the one in the tractor.

The best fix would be to build it up with weld and then turn it back to size and re-key. If you can remove it I have the equipment to do it.

thanks for all of the help everyone, I guess I will take a closer look this weekend and see what makes the most sense. I haven't pulled a BGB apart yet, if I decided to have the shaft done at a shop how difficult is the disassembly, are there alot of parts.

This diagram might help you determine if you want to try it. Actually the hardest part is removal from the tractor.
