Re: Drive Coupler Not Staying Engaged, Craftsman 101.21200 MK2


 

The only machine tool I have here that was new or well-overhauled when I got it is my Atlas TH42, and it needed a good hosing down with WD-40. :) I have overhauled a couple more, and one of them needs to be overhauled again. :(

Someday I'd like to buy something that is ready to work as soon as it lands on the bench. Not holding my breath waiting. ;)

Expect in one hand, expectorate in the other. See which one gets full first.

Good possibility. A little WD-40 or some brake cleaner might free it up.?

Well, color me embarressed...? Thanks for pushing on this guys...

Didn't look very dirty from the outside...


A bit of Kroil and Q-tips freed it.? Cleaned the pocket, good bit of crude in there.


I tried to lose the ball twice and nearly succeeded, had it neatly in my hand, then dropped it.? Looked for it for a while but gave up and fished a replacement one out of my supply of steel balls and put it back together.? Still came out.? Spent more time looking for the original, on the floor with the flashlight, like the CSI guys.? Voila!


Getting it back on the spindle was a task.? Both the key and ball liked to escape and hide.


All back together, with some improvement.? It doesn't slip out in the second highest speed now, but does still at the highest.? I'll try it with one of the new springs when the order from eBay arrives.? I've located on spring on McM-C that is close the original spring (1/8" OD, 3/8" length, 0.021" wire dia.) but is longer (1") so I can trim to some lengths greater than the stock spring.
