Resposta para "Planetary Drive head keeps falling out during use"After cleaning the housing and shaft squeaky clean, I applied two part epoxy to the splines on the shaft and installed into housing. I let the epoxy completely cure before drilling my 1/8” hole then installing the 1/8” spring pin. In my photo you can see the epoxy squeezed out about a 1/16". This prevented the upper ring gear from fully seating where I could not install the pin through the shaft. I used a razor knife to cut the epoxy off flush and everything fit perfectly!
