Buckshot,
Welcome aboard.
First, although you will have to remove the headstock from the bed in order to change the two A42 spindle belts and that will take you a while, you will probable never have to do it again. I bought my 3996 new in 1981 and am just now needing to change the spindle belts. And the motor belt and countershaft belt are easy to change once you have the spindle belts changed and the headstock back in place.
I am not going to tell you not to use link belts but decent quality ones will generally cost you more than V-belts, are not rated to run in reverse, and some other negatives compared to V-belts. And if anyone ever made link belt replacements for the A-Series belts, I've not seen them.
In the Atlas section of Downloads, you will find among other things a technical bulletin detailing how ti change the spindel belts. The only drawback is that access to Downloads requires Donor status (any level from $10.00 per year on up). Files in Downloads are organized first by brand or maker.. After you are in Downloads (click on Downloads in the main menu at TOS), follow the first two instructions (Click Here First and Click Here Second), scroll down and click on Atlas. Then find and download what you wish. Including the file on the headstock and the 3995/3996 owner's manual (and anything else that looks interesting). We also have copies of some of the factory parts drawings stored under Drawings.
I will also add that access to sell things on the site for historical reasons costs $25.00 per year. The Donor software that we use was actually written by PayPal and has no provision for up or down grades other than waiting until a year has passed.
Clausing Industrial still supports the 3996 to some extent. Be advised, however, that for the most part, new parts are mostly priced at what they would cost today, not what they would have cost circa 1967.
