My replacement part for rear drive pulley just about done.
I have to jig up the part now to bend the tabs so that they are to the cone shape that the spokes make going from hub to rim.
Hopefully the drill holes are close to where they should be.
An axle tool of sort is next. It will pull or push the axle to the rear of the drop out tightening the belt. Putting the belt on should be easy with it slack and not damage the pulley.
The adjustable diameter pulley on one of the twin stacked jack-shafts will go to this rear drive pulley, so I can have it be just enough tightness not to slip. Very important also is that it is not so tight that it crushes or cracks or fold or spindles or mutilates the rear drive pulley.
Similarly I will be doing something for the other large pulley that is spoked and also may be prone to this cracking. Now that I chose to use vee-belts that have next to no stretch as the link type belt that I first tried, I have to be very careful!
I may see about the link type belt, but the Accu-Link is not going to be used, it stretches too much. The Power Twist Plus is way more rigid and if necessary to get a length that if I cannot get in a regular vee-belt I will try that.
Just to clarify: The one tab that is broken off on the pulley that cracked along a short portion by the vee-belt slot was not due to the belt being popped into place. That actually happened when I was bending that tab back to allow copying the drill holes accurately to make a replacement pulley.
It does prove that bending one direction is all that can be done. If you bend it back it may crack, but this is not what I would be doing with a pulley that is finished and ready to install. Therefore it is of no consequence.
