The Eaton Fuller countershaft rear bearing cover shim, part number 3315683, is used to set proper endplay and preload on the countershaft rear bearing during transmission assembly. Shims like this go between the bearing cover and case at the countershaft rear support, letting a technician dial in the correct clearance for smooth gear engagement and consistent bearing life. Correct shimming is a routine step when servicing or reassembling the countershaft, so keeping the right part number on hand avoids guesswork at the bench. This is a genuine Eaton Fuller part from Pro Gear and Transmission. Not sure this is your part? Give us a call to confirm proper fit for your transmission.
