Ok, so I found that bike chain is #40. Now I'm looking for the shaft extender bushing. Do you know how long of one I will need or is that going to depend solely upon which centrifugal clutch I choose. Also should I be looking for a clutch that is smaller than 4"OD?
Thanks again for all your help!
The length of the bushing varies depending upon the width of the clutch. I bought the clutch for my project that uses the Honda GXH50 without a gear box from http://www.maxtorque.com. They offer a special clutch that has been optimized for use on the Honda motor and will ask you what length shaft your motor has as there are at least 2 different lengths. (1&1/4 and 1&5/8) The clutch I bought from them was the one they offer with a 5mm Metric Timming Belt Driver and happens to be quite wide but the clutch with a #41 Chain driver is probably quite a bit narrower. The cost of the clutch from Max Torque was more than other outlets but came with every thing needed to just mount it right up to the Honda motor. Send them an e-mail or call them you will probably be dealing with a man named Jim Donavan he owns the company and he has alot of knowledge and is more than happy to share and help out.
Why is the OD of the clutch important if you are not using one of the gearboxes?
