I spent some time yesterday replacing the original engine panel (Universal M4-30) buttons/switches and ran into a problem. I had bought a new Cole Hersee key switch and two push button switches for the replacement. I was able to replace the key switch and the glow plug button easily (only a small amount of blood and pain). However, I realized that the original push button start switch is different from the glow plug button. The glow plug button has a rubber hood that can be easily removed and a knurled round collar nut on the outside and another nut on the inside to secure it. The start button has a rubber hood that appears not designed to be removed and a rounded collar piece with no knurling that secures it on the outside. I have been unable to remove that collar and it is not clear if it is threaded. The inside nut is different as well, and it is so tightly spaced to the body that I have not found a tool thin enough to get to it and loosen it. Anyone have suggestions on:
1. Why these two push button switches are different when the presumably perform the same type of function? 2. A flat tool that can get to a narrow space for a large nut (something like a bicycle pedal wrench but adjustable)? 3. How that start push button switch is supposed to come apart?
