Ruger Wrangler Cylinder Won't Turn: Corrosion Teardown | Over the Gunsmith's Shoulder Ep. 39

This Ruger Wrangler came in with a cylinder that barely turns and a loading gate that needs a screwdriver to pry open — the owner thought he bought a lemon, but the real problem was how the gun was stored. In this episode of Over the Gunsmith's Shoulder, Master Gunsmith Ken Brooks walks you through diagnosing and fixing a corrosion-bound Ruger Wrangler single-action revolver. Ken starts with a safe clear check, then digs into the symptoms: a binding cylinder, a center pin that won't come out, and a gate that sticks shut. The history tells the story — the gun lived in a leather holster in a car trunk in the Pacific Northwest, and that leather drew moisture straight into the aluminum, flaking the anodizing and leaving corrosion in the action, the ejector housing, and on the center pin. ✅ How to diagnose a single-action revolver that binds ✅ Why leather holsters and car trunks breed corrosion — even with silica packs ✅ Spotting corrosion on aluminum: flaking anodizing and white crud ✅ Safely checking a revolver when the action is stuck ✅ Ruger Wrangler teardown, step by step ✅ The loading gate spring that doubles as the trigger pin retainer ✅ Freeing a gummed center pin latch assembly ✅ Recognizing sticky, degraded gun oil ✅ The extra-long screw that retains the hammer pivot pin ✅ Reinstalling the transfer bar with a gravity assist ✅ Where moly grease belongs: ratchet pads and gas ring ✅ Checking barrel-cylinder gap on all six chambers — and why one isn't enough ✅ Storage advice that prevents the whole problem This is the kind of practical, real-world gunsmithing you only learn by watching a pro do it. No fluff — just hands-on skill. 🔧 Want to learn real gunsmithing from certified professionals? 👉 https://americangunsmithinginstitute....

A: It isn't always a broken part. On this Wrangler, corrosion and dried, sticky oil had the action bound so tight Ken couldn't even check the timing until it came apart. Once cleaned and oiled, the cylinder turned and timed correctly — nothing mechanical was actually broken. Q: Is it bad to store a gun in a leather holster? A: Yes — leather draws moisture and holds it against the metal. This gun sat in a leather holster in a car trunk (with silica packs nearby) in the Pacific Northwest, and the leather still fed corrosion into the aluminum. Ken's advice: take it out of the leather and don't store it in the trunk. Q: How do you remove the loading gate spring on a Ruger single-action? A: Carefully — on these Rugers that spring is also your trigger pin retainer. On this gummed-up gun it fought back; Ken worked it from the other direction, used a punch from the back side, and kept tweezers ready so the small parts didn't drop out. Q: Why check barrel-cylinder gap on all six chambers instead of one? A: Because the cylinder face may not be true. You can have ten thousandths of gap on one chamber and three on another — free in one spot, then dragging on the barrel and binding as you work the action. Ken tilts the gun up and checks the gap at every chamber when he cocks it. Q: What grease do you use on revolver ratchet pads? A: Ken puts moly grease on the ratchet pads and the gas ring, because those surfaces drag on the breech face every time the hand rotates the cylinder. Q: Does corrosion mean the gun is ruined? A: Not necessarily. The flaked anodizing and the mottled finish on the center pin are permanent cosmetic scars, but after a thorough clean and oil this Wrangler's loading gate opens with a thumb, the ejector works, and the timing checks out. 00:00 — Cold Open: A Cylinder That Barely Turns 00:55 — Gene Kelly Intro: Over the Gunsmith's Shoulder 01:31 — The Ruger Wrangler & the "I Think I Got a Lemon" Complaint 02:56 — Diagnosis: Corrosion from Leather-Holster, Car-Trunk Storage 04:42 — Teardown Begins: Tiny Torx Screws & Sticky Gun Oil 07:49 — Fighting the Loading Gate Spring (It's Also the Trigger Pin Retainer) 09:35 — Center Pin Out: Corrosion in the Action & Ejector Housing 11:51 — The Verdict: Nothing Broken — Corrosion Is the Defect 13:46 — After the Cleaning: What the Corrosion Left Behind 14:45 — Reassembly: Trigger Spring, Hammer Pin & the Long-Screw Trick 16:37 — Transfer Bar, Center Pin & Moly Grease on the Ratchet Pads 18:50 — Function Checks: Timing + Barrel-Cylinder Gap on All Six Chambers 20:01 — Final Tests & the Storage Advice That Prevents This 21:30 — Like, Subscribe & Learn Real Gunsmithing
