NW Washington | Yes, that pictured "sheave" is for a taper lock hub. Some of the holes are for tightening the sheave to the hub and the others for pushing it off.
Grainger has a good supply of sheaves and hubs. A good bearing and power transmission store would be a better place to look. Here is an online power transmission dealer: http://www.kamandirect.com/
There is probably an SAE spec. for the bolt pattern on the gear box hub if you knew where to look for it. Do you have a spec. sheet for the gearbox? | |
