I find I need at least a 30" X 3/4" X 4" wide board that I drill a 1 1/8" hole half way through the center of the board, then finish the hole with a 3/4" drill bit. This allows the board to fit over the washer or nut and you can get to the snap ring much better to remove and install it. I am able to hold the longer board down with one arm and hand. This prevents the board from slipping off the end. If a nut is used, then I turn the motor sheaves to unscrew the nut and reverse to install while holding the spring compressed.

There have been three versions that I have encountered. The oldest is the threaded/nut. Next is the cup, and finally the washer.

The washer version truly needs a compressor like Bill described. I have made one that I slip under the headstock web. Then rotating it to more securely be captured by the web. Then press down on the other(longer) end.

FWIW with the cup, I am able to push/hold it by one hand. Yes it is dicey!:rolleyes:

I may be a little fuzzy headed today, but am having trouble visualizing the suggested spring compression ideas and the variations being described.

Generally, I think the ideas revolve around putting the spring on a dowel and having a board with a centered hole that can slide down the dowel compressing the spring over the shaft/sheave base exposing enough of the shaft to put on the retaining ring. That was pretty much what I got from the beeg's PDF link after reading a couple of times.

I'll have a friend help me with the dowel and stick approach. The end of the shaft has a dimple so I will put a finishing nail in the end of the dowel to help hold it on the shaft.

If this does not get the thing back together, I may have to take a smart pill and re-look at the suggestions. Thanks for the help.

Sheesh! A lot of verbage with no details of the most important activity(removing the spring retainer etc.).

And that 20" dowel - for WHAT?

At 8:30+ removal takes place.

Reverse actions to get er back on. See previous comments re safety etc.

So, we got it all done! But not without the spring getting loose once...a safety tip - don't work directly under florescent bulbs:eek:

We did not break them, but it was a near thing:D

Speed changes work fine now:)

Thanks for the help. I used 5/8" dowel a little longer than the spring. I took about 3/16"-1/4" off the midsection of 24" 1x scrap where the hole was drilled. Tried 3/4" hole had to enlarge to 1" so the board would clear the snap ring.

Thanks again
