Installing Kelford 208-B Cams in the Toyota 3UZ-FE — Scissor Gear Swap Explained | E82 Build Ep.X

Upgrading to Kelford 208-B performance cams in the Toyota 3UZ-FE V8 — and the step most guides skip entirely: correctly removing the OEM scissor gear sprockets and transferring them to the new camshafts without damaging the spring-loaded assembly. The Kelford 208-B runs 264/258 degrees of advertised duration with 9.60mm/9.50mm lift — a fast road profile designed to work with the stock head casting and suit upgraded intake and exhaust. On a tuneable ECU, these cams are a clean performance step that doesn't sacrifice streetability. But before any of that matters, the scissor gear has to go on correctly. This video covers the full process. 💡 WHAT IS THE SCISSOR GEAR? The 3UZ-FE uses a spring-loaded dual-gear (scissor) assembly on the camshaft drive sprockets to eliminate backlash and gear noise. Unlike a conventional single gear, the scissor arrangement uses a secondary preloaded gear to take up any play in the timing chain drive. When fitting aftermarket cams, this assembly must be carefully disassembled and transferred — the spring preload has to be maintained correctly or you'll get timing noise and potential wear issues. 📐 CAM SPECS — KELFORD 208-B: Duration (advertised): 264° intake / 258° exhaust Lift: 9.60mm intake / 9.50mm exhaust Application: 1UZ-FE / 2UZ-FE / 3UZ-FE VVT-i Profile: Fast road — suits stock head, upgraded intake/exhaust, tuneable ECU required 📺 FULL BMW E82 TOYOTA V8 SWAP PLAYLIST: [Playlist link] Previous Episode — 3UZ-FE Head Porting & Polishing: Next Episode — Head Assembly & Valve Installation: 📸 FOLLOW THE BUILD: Instagram: axlworks #3UZFE #KelfordCams #ToyotaV8 #CamInstall #ScissorGear #BMWE82 #V8Swap #EngineRebuild #3UZ #1UZTech #PerformanceCams #GarageBuilt #EngineBuild
