Irish, I wasn't the one that posted about the key jammed in the clutch. Both of my gear boxes are GruBee with the decals in the gear cover.
I now have four clutches. Two have the proper keyway, but all are of the same construction. One does have three tapped holes, one in each clutch section. Don't know what they were for?
Looks to me like several shops produce the same item, so may have different manufacturing methods.
When one of my companies started to manufacture large valves in China, we saw knockoffs of our design in SE Asia within two years.
GruBee may have a US patent on the box, but that won't stop China from making as many as they want.
BTW, I can see the return spring (one spring around all three shoes) on each of my clutches on the side that goes to the engine. It doesn't seem like you can see the spring on the Hoot?
