Overview – GAUGE, MAIN BEARING BORE RING 3376717
3376717 is the CUMMINS part number for this GAUGE, MAIN BEARING BORE RING, fitted in Cummins diesel engine main bearing bore measurement. We can quote this number with or without related components.
Parts Characteristics
3376717 is the CUMMINS gauge ring used to check the main bearing bore diameter during engine assembly and overhaul. The ring is machined to the original reference size with a honed bore and marked faces, so the bore gauge can be zeroed against a known dimension before the block is measured. The steel is stabilised so the reference size stays constant through workshop temperature changes.
Applicable Models & Applications
This gauge ring is used with CUMMINS diesel engine main bearing bore measurement procedures, where the block bore is checked after line boring or during bearing selection. Confirm the ring size against the engine model and the bore gauge range before ordering. The gauge is used on the engine families that share the main bearing bore specification, and we can confirm the correct ring from your engine serial.
Maintenance & Replacement
Keep the gauge ring clean and oiled, and store it away from impacts that could distort the bore. Wipe the measuring faces with a lint-free cloth before each zeroing, and check the ring against the bore gauge at the same temperature as the block. Have the ring rechecked against a master periodically, and replace it if the bore shows scoring or wear.
