Oiling sheeves

[whitehat1994]

Greetings,

I oiled my Mark V 510 a couple of weeks ago. I was not able to see the oil hole in the lower sheeve shaft. I used a screw driver to widen the spring and turned the shaft and never saw the hole. I went ahead a dropped a few drop of 3-1 oil on the spring.

The speed dial is still maybe a little tough to turn. I'm not sure how easily the speed dial should turn.
Feedback appreciated!

Thank you

Richard

Hi Richard. I believe you have to run your headstock up to high speed and shut it off. Then when you spread the spring you will see the oil hole.

Ahhhhh....thank you. I do believe I remember reading that somewhere! LOL

You're welcome. Here's a link to some instructions: http://www.shopsmith.com/ownersite/prod ... e_1_10.pdf

It is often not enough to just put a few drops of oil into the hole beneath the spring.

One of the most overlooked lubrication is oiling of the motor sheave shaft . It is not enough to oil only through the hole that is hiding in the spring. It is a better thing to put the Shopsmith into the drill press position, run the speed up to high and and flood oil the shaft. Let the oil soak/seep between the shaft and sleeve. Then lower to saw position and by hand, slide the outer sheave out several times until you feel it sliding more easily. Do this sliding smoothly! Don't let the sheave bang back into the motor sheave.

This spring loaded sheave is often the major cause of hard turning toward lower speeds. This is especially true after long periods of non lubrication.

Wipe off the excess oil - lower the machine from vertical and try the full movement of the speed control. This should help your situation so you can more easily lower speed.

I might also mention that failure to properly lubricate the motor sheaves puts excessive strain on the pork chop and associated speed control parts. Proper lubrication is really more important than the type of oil used.

Sometimes I wonder about what pops into my mind when I am working on something.

One day I recall disassembling a headstock and as I was carrying parts in for cleaning and inspection, the lyrics just came..... Bringing in the Sheaves.... Bringing in the Sheaves; Guess I'll be re-oiling.....

You had to be there I guess, for that to make any sense at all....

Makes perfect sense to me. That song came to mind just reading the subject heading.
