Sargent 94-0018 – Frequently Asked Questions

1) What exactly is the Sargent 94-0018 part?
It's an inner chassis spring, a genuine Sargent OEM replacement component that sits inside the lock chassis of Sargent commercial mechanical lock assemblies. Its job is spring tension: when the lever or knob stops returning crisply to horizontal, or the retraction feels sloppy, a worn or broken inner spring is usually why. Model number to order by is 94-0018.
2) Do I have to replace the whole Sargent lockset, or can I just swap the spring?
If the failure is the inner chassis spring, the 94-0018 goes in as a direct drop-in and returns the lockset to proper factory operating condition, so a full hardware replacement isn't needed. That's the usual call on a lever that won't spring back but otherwise latches and keys fine.
3) Will the Sargent 94-0018 spring fit a Corbin Russwin or Yale lock chassis?
No. It's a Sargent chassis spring and fits compatible Sargent mechanical lock assemblies only. For Corbin Russwin work, ZenSupply carries Corbin Russwin's own small parts, such as the Corbin Russwin Swivel Spindle Pin x Set Screw, listed for 1-3/4 inch doors. Match the part to the brand of chassis in the door.
4) Can a Corbin Russwin swivel spindle pin and set screw be used in place of the Sargent 94-0018 inner chassis spring?
No. The Sargent 94-0018 is an inner chassis spring, a tension component inside a Sargent commercial mechanical lock chassis that restores proper spring tension and smooth lock operation. The Corbin Russwin 499F838 is a swivel spindle pin with a set screw, which secures a spindle rather than providing chassis spring tension, and it is specified for 1-3/4 inch doors. They do different jobs inside a lock, so one does not fill in for the other. For a Sargent lockset with a worn or broken chassis spring, the 94-0018 is the OEM part that drops into the original specification.
5) Will a generic spring work in place of the Sargent 94-0018?
Use the Sargent part. The 94-0018 is built to the tolerances of the original specification for Sargent chassis, and chassis springs are tension-specific, an approximate substitute either binds the lever or fails to return it. Ordering the OEM number is the only way to be sure the tension matches what the chassis was designed around.
6) My lever is loose on a commercial lock - do I need a chassis spring or a spindle pin?
It depends on which part has failed. If the lever returns slowly or droops because tension inside the chassis is gone, the spring is the part to change, and on Sargent commercial mechanical locks that is the 94-0018 inner chassis spring, sold as an OEM replacement part. If instead the lever or knob is loose on the spindle itself, the retaining hardware is the issue and a swivel spindle pin with set screw, such as the Corbin Russwin 499F838 for 1-3/4 inch doors, addresses that connection. Diagnosing which of the two is worn before ordering avoids a second trip to the opening.
7) Is the 94-0018 spring rated for high-traffic commercial doors?
Yes, it's a commercial-grade part, catalogued by Sargent for commercial rather than residential use, and intended for high-use door hardware. It shows up in office buildings, schools, hospitals, retail, warehouses, multi-tenant residential and government facilities.
8) How do I order the Sargent 94-0018 and how many configurations are there?
One configuration only, no finish or handing choice to make, since the spring is internal to the chassis. Order it by the Sargent part number 94-0018.
