Product Introduction: This CNC Machined Camshaft Timing Lock Tool is a high-precision dedicated fixture designed for automotive engine maintenance, specifically for DOHC engine camshaft timing locking during timing belt/chain replacement and engine overhaul. Manufactured by 3-axis/4-axis CNC milling and precision drilling processes, it adopts high-quality Aluminum 6061-T6 or 7075-T6 material, featuring lightweight, wear-resistant and camshaft-protective properties. With machining precision of ±0.01mm – ±0.02mm and strict compliance with ISO 8062:2008 tolerance standards, the tool ensures accurate camshaft positioning, effectively preventing valve and piston collision during maintenance. It supports OEM/ODM customization according to different engine models, with optional clear anodizing, precision milling or polishing surface finish, widely used in the automotive repair tool industry and favored by maintenance technicians for its easy operation and durability.
