Hardware Store:
Buy a stainless steel dowel pin or shoulder bolt (cut to length).
Machine Shop:
Can fabricate a custom pin from heat-resistant steel.
Remove the old pin:
Tap it out with a brass punch (to avoid damaging threads).
Lubricate the new pin:
Use high-temperature anti-seize compound (e.g., Permatex 80078).
Secure the pin:
Some models use retaining clips or cotter pins to prevent slipping.
Stainless steel bolt: Match the diameter, grind the head smooth.
Ream and sleeve: If hinge holes are worn, insert a bronze bushing.
Ensure the door closes tightly after replacement to prevent smoke leaks.
Test with a dollar bill (should resist pulling when closed).
