Author Topic: E-7 Main Drive Gear Stud/Stud Nut Will Kutler Phenomenal Film Handler Posts: 1506 From: Tucson, AZ, USA Registered: Feb 2001 posted 07-11-2009 05:05 PM                     Has anyone ever attempted to modify the N-248-G Main Drive Gear Stud Nut with some type of roller bearing/bearing assembly? These nuts are pleagued by eroded flat spots on every E-7 that I have ever seen.

I don't think they ever did for the E7, which was pretty good right out-of-the-box.

Still had to oil the shaft though. Kalee had a ball bearing main drive gear that was extremely robust. If you want to mess with a projector that has the best fit and finish of any projector ever made get yourself a Kalee 21. It's even better built than the DP-70 IMHO. Mark  |  IP: Logged
