Ed, if you continue to do it yourself, the end result will be tossing good money out. Have a professional check the system and save the unit from permanent damage. Chipping parts of a gear off means a serious resistance force or action has occurred. One force is slowing down as the other is speeding up. Gear alignment can be moved off center, or a sudden application (sudden stop or start) can damage the least resistant parts. For example, when a hook turns within the mixing chamber and the resistance of the content is too great on the turning shaft and gears, which ever part is weakest will break. Complicated I guess.
Testimonial: "I am not trying to throw good money out. I am trying to do just the opposite. The local service Co. wants $94hr to check it out. If I can figure what might be causing it to shear the keys I can fix it. I have been doing a/c service for 20 yrs. It is not chipping parts off of a gear. I found no teeth worn, or binding. With no resistance it sheared part of the key off."

Check the spring pin that locks the motor shaft to the main drive gear in the gear box. You should be able to turn the motor from the back at the cooling fins and watch the shaft spin in the gear, that is if the pin is sheared. That is a common problem. if you plan on keeping this machine for a while, i recomend that you spend a little more on a quality spring pin,

What you are calling the spring pin, is that the same thing as the key? 2nd & 3rd speeds are working properly. Thank you for your response.
