C-101 ignition switch cleanup

[Pullstart 64,878]

I thought for reference, I’d toss this in the electrical section.  I was having issues loosing power at the coil in the run position, but it had power in the start position.  I used some channel locks and pulled apart the swedge flange and this is what I found.

 

 

some brake clean and a wire brush cleaned the brass parts up well!

 

 

a little dielectric grease applied

 

 

and using the ammeter, I was able to prove that I had power to the coil once again!

 

ignition off

 

 

ignition on, engine off.  You can see a draw from the coil.

 

 

 

 

After peening the flange back down, I was able to run Frank for a short while!

 

then it would not start again...  and this is where I forgot to take pictures, but I pulled it apart again and found a ton of debris from the plastic tumbler had come off and contaminated the grease.  I pulled the plastic and found more springs and decent balls. I’m just going to say that after cleaning all the junk out, grease the springs, put greased detent ball bearings on the springs, and re-assemble with the aluminum casting up nd the components underneath.  It keeps it all aligned much better.  Then re-assemble the switch portion.

 

Happy Frank!

Good post!

I do them all the time and always have spare cleaned switches to replace one quickly if needed, then clean up the replaced one when there's an opportunity to do it. 

Same thing with solenoids. Both are fairly simple to take a part and clean, Just replace the rivets with screws to reassemble the solenoid.

 

It's a good way to have spares handy.

I took one of those 70 amp flavors apart once just because enquiring minds want to know. It would have took abit to save but I could have if I didn't have 3 new ones from the BS on the shelf.

Not all are able to be saved.   The internal rivets come apart, the plastic  does fail,   parts wear down .

 

But a good primer on rebuilding a switch.

Unrelated but the same scenario happens with cheap Chinese electric tools when the inside of the switch fills up with fine sawdust particles. They end up in the landfill, I have brought so many home fixed and given most away.
