Abstract
A cam assembly is provided for adjustment of a drill feed guide wear pad. The cam assembly has an eccentric bushing with a shank portion extending circumferentially about a first axis and defining a bore along a second axis. The second axis is generally parallel and offset from the first axis. The bushing has a head portion extending from the eccentric bushing portion, with the bore extending though the head portion. The bushing is sized for insertion into an aperture of a drill feed guide wear pad, and is rotatable causing the shank portion to engage the aperture of the wear pad to provide a camming action to position the wear pad relative to a drill feed guide. The head portion is shaped to interact with a tool for rotating the bushing.
