Medeco CP-031170 – Frequently Asked Questions

1) What exactly is the Medeco CP-031170 part?
It's the X4 locking pin spring, a small internal spring that sits behind the locking pin in compatible Medeco mechanical lock cylinders. It is a genuine Medeco replacement component, not a complete cylinder or a pin kit, so you are buying the spring alone to restore proper spring tension on the locking pin.
2) Will the CP-031170 spring work in any Medeco cylinder?
No. The CP-031170 is built for X4 series Medeco lock cylinders and the spring tension is matched to that configuration. If the cylinder you are servicing is not an X4, this is not the spring for it.
3) Can a Corbin Russwin swivel spindle pin and set screw be used in place of the Medeco CP-031170 locking pin spring?
No. The Medeco CP-031170 is an X4 locking pin spring, a genuine Medeco replacement component that supplies spring tension for locking pin engagement inside compatible Medeco mechanical lock cylinders. The Corbin Russwin 499F838 is a swivel spindle pin with set screw, a spindle retention part used on Corbin Russwin trim rated for a 1-3/4 inch door thickness. They serve different mechanisms in different manufacturers' hardware, so one cannot stand in for the other. For a Medeco cylinder rebuild, order the CP-031170.
4) I am rebuilding lock trim on a 1-3/4 inch commercial door and the spindle keeps backing out. Is a Medeco locking pin spring the right fix?
That symptom points to spindle retention rather than a cylinder pin spring. The Medeco CP-031170 is an X4 locking pin spring that restores proper locking pin operation inside Medeco cylinders; it does not hold a spindle in place. For a spindle that will not stay seated on a 1-3/4 inch door, the Corbin Russwin 499F838 swivel spindle pin with set screw is the part built for that job on Corbin Russwin trim. Use the CP-031170 when the cylinder itself is binding or failing to return pins.
5) Should I use an aftermarket spring instead of the Medeco CP-031170?
For a Medeco cylinder, use the OEM spring. Locking pin function depends on the tension being exactly right, and the CP-031170 comes from Medeco's own parts and accessories program, so the fit and spring rate match what the cylinder was built around. A generic spring that is close but not identical is how a rebuilt cylinder ends up binding.
6) I need a swivel spindle pin, not a lock cylinder spring. Is this the right part?
No. The CP-031170 is a locking pin spring for Medeco cylinders. If you're after a spindle pin for a lever or knob spindle, look at the Corbin Russwin Swivel Spindle Pin X Set Screw instead, which is listed for 1-3/4 inch doors. Different part, different job.
7) Does the CP-031170 come as a kit with pins, or just the spring?
Just the spring. CP-031170 is a single replacement component in Medeco's parts program, ordered on its own. If your rebuild also needs locking pins, tailpieces, or cams, those are separate line items.
8) Are small lock repair parts like these brand-interchangeable across a mixed commercial facility?
Generally no, and these two are a good illustration. The Medeco CP-031170 is a commercial-grade OEM locking pin spring made to Medeco's tolerances for X4 series cylinders, so fit and spring tension are matched to Medeco assemblies only. The Corbin Russwin 499F838 is a swivel spindle pin and set screw dimensioned for Corbin Russwin trim on a 1-3/4 inch door. In a facility running both brands, stock the repair parts by manufacturer rather than treating them as a common pool.
9) Is this a residential or commercial lock part?
Commercial. Medeco lists the CP-031170 under its commercial mechanical lock parts, and it is the kind of component a locksmith or in-house maintenance team consumes servicing office buildings, schools, hospitals, government facilities, warehouses, retail, and multi-tenant residential.
