John Deere 4361763 Door Lock Assembly

The John Deere 4361763 door lock assembly is a cab access component designed for hydraulic excavators. It integrates a door latch mechanism (4355970), exterior handle assembly (4369634), and lock cylinder (4361637) into a single serviceable unit. The assembly mounts to the cab door structure and provides secure latching with keyed locking capability. Constructed from high-strength steel with a corrosion-resistant black finish, the assembly withstands vibration, impact, and environmental exposure typical in construction and mining applications. The latch mechanism uses a rotary cam design engaging a striker plate on the cab frame. The handle assembly incorporates a spring-return lever with ergonomic grip. The lock cylinder accepts the standard John Deere key profile. This part number cross-references to Hitachi excavator applications including EX100-5, EX120-5, EX200-2, EX200-3, EX200-5, EX300-5, EX400-5, EX60-5, ZX330, ZX600, and ZX800 models, indicating shared cab architecture between manufacturers. Installation requires basic hand tools and alignment adjustment of the striker for proper latch engagement.
