Any suggestions for small Pulley puller?

Post by kristenanne77 » Mon May 18, 2015 7:32 pm

I have a feeling I might have to move a pulley a little bit away from the motor.
And I know for a fact they are on tight and will not budge.
Any suggestions for a small pulley puller that will fit within the ShapeOko 3 design to help ease the pulley "gently" away
from the motor (without having to physically remove the motor)? If the motor has to be
removed ... so be it, but I would prefer not to. Something inexpensive.

Thanks

Hi K
I think that happens to most of us with these pulleys. I found with a fine long nose plyer and being very carefully, AND on the SOLID side of the pulley I had no problems to remove them.

What if the solid side is closest to the motor?

I used a 5 in 1 to go between the pulley and motor, the blade has a small bevel to it and is heavier duty than just a putty knife and was able to move the pulley into alignment. If you need to you can use two for leverage.

If you're not familiar with it, they are usually in the paint department.

I've made my own before, it's relatively cheap to do yet effective and allows for even distribution of pulling force. If you take a piece a stock and cut a void that will allow you to slip it over and under the pulley all you have to do is drill and tap a hole smaller than the diameter of the motor shaft, slip it over the pulley and insert and tighten the appropriate size bolt for the whole you tapped.

You can also take 3 piece of 'strap' and a couple of spacer and bolt them together to make the puller. I've also built a reverse design before for inserting bearings as I don't have a press.. just a thought...

Just try a fine pointed player, there is plenty room to go underneath, or like LTEPM suggested.
