I have a manual for Comet mills . Mine is a 1986 3kvhd bur the manual covers the 2s,2v 3v and 3kvhd series mills. ths difference is the hp of the motor and the ead drive the 2s is belt and pulleys and the v"s are vari belt drives. the file I have is jpeg scans of the paper manua land is 31meg. so I don't know if it will email or not.
Before I got the manual I used a manual for the Bridgeport series 1 Jhead and the parts breakdown is the same.
I will try to send it to you if you still need it. PM me an email address if you want me to try. If it won't go that way I can mail it to you on a thumbdrive.
I am trying to find what belt fits the varidrive but can't a good part number for it. the belt on my mill only lasted 20 hours or so and brokedown badly so I don't think it is the correct belt. If you can read the size or belt mfg and part number I sure need it.
