Author Topic: Century motor adapter plate Michael Schaffer "Where is the Boardwalk Hotel?" Posts: 4143 From: Boston, MA Registered: Apr 2002 posted 06-10-2004 04:10 AM                        Today I installed a new motor on a Century R3-E. As you all know, the motors shipped out by Strong/Ballantyne these days are made by Leeson. The ex-motor was a GE. Which has a different overall size and the feet are spaced differently. So you also need the adapter plate for the mounting bracket. Now, the problem was the 4 slots in the adapter plate were too narrow for the old bolts to go through. Obviously slimmer bolts would have, but they wouldn`t have fit into the threading on the original bracket. So I filed the slots out. Why is that? Are there some types of Century brackets which use slimmer bolts? Yes, Mark, I have the manual/parts list (and so does our dealer) but didn`t find different adapter or mounting plates in it.  |  IP: Logged Richard Fowler Film God Posts: 2392 From: Ft.

Dealers where lucky to have the shop drawings of changes as they happened but many times never made it into the service manuals in a timely manner. The GE sync motor was variation from the ORC ownership days.  |  IP: Logged Michael Schaffer "Where is the Boardwalk Hotel?"
