Installing One Way Vacuum Adaptor on Jet 1642

[David Moore CA]

I am trying to install a vacuum system on my Jet 1642. I have the One-Way Rotary Adaptor with their taper adaptor for my 1642. I have removed the handwheel and the piece (locknut?) behind it but when I try to screw on the One-Way piece it only will go on to about the first thread on the screw. Thanks if you have any suggestions.

The lock collar is still on mine the adapter is part #399

Thanks David. I guess then that the One-Way Adaptor just slides on rather than screws on? I've about come to the conclusion that my vacuum pump may be bad. It was a freebie so no big deal but I may need to acquire another one before I can do much more.

Hi David:

I just sold my 1642 with the adapter, but you should only need to remove the handwheel. The adapter should have a stub sticking out of the back with a couple of o-rings on it. This slides into the spindle, and you're done. Mine worked great.
