Adams Rite 28-0903 – Frequently Asked Questions

1) What lock does the Adams Rite 28-0903 spring fit?
The 28-0903 is the factory replacement spring for the Adams Rite G86 mechanical lock assembly. It is a drop-in part for that assembly, made to the same specification as the spring it replaces, so it restores the original spring tension without any modification to the lock.
2) My G86 lock feels sluggish or the latch is not returning. Is a spring the part I need?
That symptom is what the 28-0903 addresses. It is sold as a service part for worn or damaged G86 assemblies, restoring the correct tension profile so the lock operates smoothly again. If the spring has lost tension, replacing it brings back original function without pulling and replacing the whole lock.
3) Can a Corbin Russwin swivel spindle pin and set screw set be used in place of the Adams Rite 28-0903 spring?
No. The Adams Rite 28-0903 is an OEM replacement spring made specifically for the Adams Rite G86 mechanical lock assembly, where it restores the correct spring tension for smooth lock operation. The Corbin Russwin swivel spindle pin x set screw is a spindle retention part - a pin and set screw that secure a swivel spindle - listed for 1-3/4 inch door thickness. They do different jobs inside different manufacturers' locks, so one will not stand in for the other. If the G86 feels loose or sluggish on return, the 28-0903 is the part to order; if a knob or lever is loose on its spindle, the spindle pin and set screw hardware is the fix.
4) Is this an aftermarket spring or a genuine Adams Rite part?
Genuine Adams Rite. The 28-0903 is an OEM factory component built to the original production specification, which is what keeps the tension profile identical to the spring coming out of the lock.
5) Do I need to order anything else to service a G86 lock along with this spring?
The 28-0903 covers the spring only, so if other internals in the G86 are worn you will need those parts separately. It is one item in the Adams Rite replacement parts line, which also covers related pieces like rings and spindles. Pull the lock, inspect the assembly, and order the additional service parts by their own Adams Rite numbers.
6) Which repair part do I need if the lever on a commercial door is loose on its spindle rather than the lock failing to return?
A loose lever on the spindle is a retention problem, not a spring problem. The Corbin Russwin swivel spindle pin x set screw addresses that side of the assembly and is listed for 1-3/4 inch doors. The Adams Rite 28-0903 is the part for the other symptom - it is the OEM spring for the G86 mechanical lock, supplying the tension the lock needs to operate smoothly and return properly. Diagnose which symptom you have before ordering, since the two parts are not interchangeable and come from different lock families.
7) Is the 28-0903 spring rated for commercial door traffic?
Yes, it is a commercial-grade component. Adams Rite lists it for commercial use in offices, retail, schools, healthcare, industrial and warehouse buildings, and government facilities, which is where G86 locks typically live.
8) For a commercial building standardizing on repair parts, is the Adams Rite 28-0903 a brand-specific item or a generic spring?
It is brand-specific. The 28-0903 is a genuine Adams Rite factory spring built to OEM specification for the G86 mechanical lock assembly, and it is a commercial-grade part intended for office, retail, education, healthcare, industrial, and government facilities. Because it is matched to the G86, it should be stocked against the Adams Rite locks in the building rather than treated as a universal spring. Parts from other lines, such as the Corbin Russwin swivel spindle pin x set screw for 1-3/4 inch doors, belong to their own hardware family and are stocked separately.
