Little belt issue this morning

My probably-needs-to-be-rebuilt 1951 transmission occasionally "pauses" between gears, today was the perfect storm of heat, RPM and pause, the result was about 120 of the 132 teeth being stripped of my drive belt.

Tried using the jam bar to get the front sprocket off which didn't work very well, then tried to remove the Primo clutch hub, again a fail. Finally did what I should of done in the first place, the old rope in the cylinder, worked perfectly, new belt on in 5 minutes.


  1. I may sound stupid but what do you mean by the rope in the cylinder?

  2. If you need to lock your primary up to pull the clutch or sprocket, feeding rope in the cylinder is an easy way to keep the engine from turning while you try to remove stuff. By filling the cylinder with rope, as the engine turns, it will compress the rope and not be able to complete the revolution.
