I have learned so much from many of you on this forum that I need to pass on what I have learned.
A year ago my DK40 with about a 100 hrs. on it went to full throttle after a restart. Called my dealer and he had a replacement installed in a few days. It now has 150 hrs. on it with no problems.
I recently talked to the mechanic and asked if they had taken my old pump apart to see what had happened to make it fail. He hadn't and allowed me to take it apart. The first and second pictures shows the broken gear tooth that jammed it full throttle. The third picture shows, for those of you interested, what is inside these things. When the mechanic saw what had failed he handed me a three cylinder pump from another Kioti. The fourth picture shows two broken teeth on the gear from it. Their opinion is that the violent action of the solenoid is breaking the teeth.
I agree with them because I found nothing else wrong. Quality of the individual sintered metal gears could be questioned since not all gears fail.
