Overview – General Parts SPRING 110-0639 Series
If you run Cummins valves and mechanisms as the spring, the Cummins SPRING 110-0639 and its series variants give you flexible sourcing without compromising fit.
Parts Characteristics
A spring that stores and returns force in a valve, injector or mechanism, holding the part to its seat until actuation releases it. It sets the timing and the seating force, so a correct, un-fatigued spring keeps the event crisp and the seal closed.
Applicable Models & Applications
Used at Cummins spring positions specifying this part. Match the rate, free length and end-form against your old spring – springs differ in how they load and seat.
Maintenance & Replacement
Inspect the spring for a permanent set and any crack at every service. A spring that has taken a set no longer returns the part, and the event goes soft.
Replace springs as a set where they work in a group. A new spring against a tired neighbour loads unevenly and the assembly loses its balance.
Confirm the rate matches the specification, not just the length. A spring that looks right but is the wrong rate changes the timing and the seat.
Keep the common springs for your assembly on the bench. They are cheap, they are load-critical, and a mechanism stopped on a spring is a machine waiting on a small part.
Price Reference (USD)
The SPRING 110-0639 generally falls in the USD 3-15 bracket, with expedited freight quoted separately.
Value & Service
We supply brand-new springs with the rate and length confirmed against your Cummins assembly, so the mechanism stays seated and timed.
