Default Ridgid Supreme Versatapper Help

Hi,
I have versatapper that needs the input spindle repaired. Does anyone know how to get the gear off so you can remove the bearing? I tried a little heat on it but no luck. I imagine it is right hand thread.
Thanks,
Dave

That's a nice head, equal to or better than TapMatic.

FWIW, TapMatic is a bear to get apart, figure a few hours on the first one, only an hour or two on the second one

The Versatapper looks like it would not be that hard, but I've never had one apart. Parts are hard to find, and you may want to pick up a second Versatapper on eBay as a parts donor.click here

I think that one will be there for a long while at that price.
Here is some pics of what I am trying to do. The spindle has some wobble to it. Some one turned it down and doesn't run true. I want to put a sleeve on it and turn it true. I cann't seem to get the gear off so I thought I might make an aluminum sleeve that I can press the bearings into and have the gear kind of broach in a bore on the back side of it to hold it while I turn the sleeve on the spindle. Any ideas on this or other methods?
Thanks,
Dave

The spindle & gear are most likely one piece, with the two bearings pressed on. Using an arbor press (don't try to do this with a hydraulic press), support the bearing nearest the gear & try gently to press the shaft out. If it won't budge that way, press it out toward the shaft end. It'll go one way or the other.

The gear already has a center in it, and the shaft will have a center in it if you're lucky. Turn the shaft down until it's .001" or .002" larger than the sleeve you want to press over it. Freeze the shaft, warm the sleeve, and press on. Turn the sleeve to correct diameter, press on new bearings, and it should be good as new

I can't say how yours comes apart, but this is the one I have model #6200.
Looks like that gear screws in.


Assuming you did not burn up the bearings. you can chuck up the shaft and retrue the shank.
You can locate off the bearings and drill a center then turn the shank between centers.


This is a guess, but the more I think about it, it looks like the gear holds everything together.
OR, I would grind the bearing races, then break them off with a chisel.

Good catch ... forget what I said about it pressing off, as both bearings are trapped between the gear and the stub shaft.

If you want to unscrew the gear from the stub shaft, which is the first step to rebuilding this part, you'll want to bore a soft jaw so the gear can be clamped without damage. Aluminum is the first choice material, but hard maple may work, depending on how much torque is needed to break loose the male-female thread contact.

Once the stub shaft & gear are separated, press off the old bearings, press on new ones, machine a new stub shaft, and it's all done. If you don't have equipment to do this, most any machine shop can handle it.

Gwiz and Precisionworks,
No center hole in the end of the spindle. I has been sawed off. I am going to make some soft jaws to hold it in and maybe use some more heat on it. It maybe loctited on. If that doesn't work I will center off the bearings. Thanks for the help.
Later,
Dave

Got the gear off and on my way to making the sleeve. Just like the picture showed, it was screwed on. RH threads.
Later,
Dave

Hi,
Got the spindle fixed. Here are some pics of what I did. I took a piece of aluminum and drill a hole in it and the split it on the saw and clamped it around the gear in the vise. Came right apart.

GWIZ
Can you tell me how much and what kind of oil the put in the tapper and what is the recommended speed to run it at?
Thanks,
Dave
