Question

why not bearing grease on bronze bushing instead of light oil?

Staff Answer
The viscosity of an oil will be lighter than grease and take up less space within the bushing.

answer 2
Grease will just "gum up" the bushing/shaft. The oil will seep into the sintered bushing and actually lubricate as the bushing heats up, releasing the oil to lubricate the surfaces.

answer 3
I used to wonder the same thing. The grease tends to gum up under those sheer loads and stops lubricating rather quickly. Bronze likes oil much better, it soaks into it slightly and lasts better. These clutches have it rough though, plan on a few drops of oil every couple hours of run time.

Question

is this clutch keyed?

I want to use this clutch on a GX120 Honda engine. Does this clutch have a key shaft?
The Honda GX120 is listed as a 3/4" shaft as is this clutch, I assume then it will work?

I look forward to your response. Thank you

Yes, this clutch has a 3/16" keyway. And should work on your Honda engine provided it has a long enough shaft length.
