VersaTapper Rebuild

Finding info on this or any other brand tapping head is getting hard to come by, as these pieces of tooling are becoming obsolete in our new CNC world order.

I did a clean and re-assemble on my Rigid Versatapper, (1 pair clutch plates shown below), but got stymied by what kind of lubricant to use inside the tapping head. The best reference I could find was for a highly viscous oil, trade name/number which was NLA (no longer available.)

I figured the oil weight was mostly an issue of preventing weeping of the product over time, and substituted automatic transmission fluid (Dexron was what I had in stock), filling the inside of the head to the fill line.

The tapping head has been in use for quite some time and performed fine with this substitution.
