Overview – ROUND HEAD BOLT C3907998 Series
The Cummins ROUND HEAD BOLT C3907998 fits Cummins engine and accessory mounting positions; because multiple part numbers interchange, we list the related series so you can match what is on your machine.
Parts Characteristics
A round head bolt that clamps the joint so the assembly stays torqued and true in the fastening, so the bolt face stays torqued and seated. It carries the service life the fastening depends on, so a true, correctly specified unit keeps the stretch and loosen from the joint walks and the seal weeps.
Applicable Models & Applications
Used at Cummins General Parts positions specifying this ROUND HEAD BOLT. Match the form, fit and contents against your old unit – General Parts parts differ in how they seat and bolt.
Maintenance & Replacement
Inspect for wear and a loose fit at every service. A round head bolt that has begun to fail lets the bolt face drift, and the drift is what causes the stretch and loosen.
Confirm the round head bolt seats and the fixings hold on fit. A unit canted in its bolts lets the bolt face move, and the move is where it fails.
Replace rather than repair a failed one where the part allows. A round head bolt reused past its life returns the same fault, and the fault is what stops the machine.
Keep the correct round head bolt for your general parts on the bench. It is cheaper than the downstream failure, and it is exactly the part missing when a service needs doing today.
