Too late now as you've bored it, but I'm surprised that you used a gear with a hub. If it was a plain gear fixed to the shaft with a keyway then the whole thing could have been considerably thinner :scratch: |

The pulley will still use it's grub screws to secure against the D-shaft. The gear is bored so I can take up some space as needed for placement. The spacers would just prevent the gear from backing up. When I was talking about placement of the gear, I meant in relation to the gear on the crankshaft... the distance between the two. I was having difficulty finding what I needed for gears. Plus, time is limited for this as I have other things that need to get done in short order before winter is here. Not to mention the lack of any real planning :smart:! McMaster Carr had these and they would work... so yeah, not the best possible solution, but I think it will work. Eh.. Live and learn I guess. |

Looked at it some more a few minutes ago. I have to redesign the bracket just a bit. The gear/pulley needs to move up in relation to the camshaft about 10mm to get decent tension on the belt. No biggie... will do it this afternoon. Eric |

Eric: I know this is late in the game, I just found this thread, but couldn't you have just put in a bell-crank to reverse the direction of throw from the shift lever? So that it was pushing the driven wheel across the output shaft to the left for the forward direction instead of pulling it to the right. I could have the direction backwards, but that's what the shiny areas in the photos seem to indicate. Don |

Don --- End quote --- Hi Don, That was an initial thought. 2 Problems with that, every speed would have been twice as fast (Cam pulley spins at half speed) and there is not enough room to get full forward speed. Wish it would have been that simple... |
