Full Technical Description
770 078 02 CAM FOLLOWER The CAM FOLLOWER acts as a specialized roller bearing inside the drifter's valve system. Its job is to follow the profile of a rotating cam, translating that motion to precisely time the flow of hydraulic oil to the impact piston. This accurate timing is what creates the powerful and consistent percussion needed for effective rock breaking.
A worn or failing follower directly impacts drilling performance. You might notice a significant drop in impact energy or hear an irregular sound from the drifter. If the bearing seizes, it can cause the percussion to stop completely and may lead to more severe damage to the cam and other internal valve components.
Replacing a CAM FOLLOWER is part of a standard drifter overhaul and should be done in a clean workshop. During replacement, always inspect the cam surface it runs against for any signs of wear or pitting. Installing a new follower on a damaged cam will lead to premature failure.
