Right-Hand (RH Passenger Side) Cabin Door Lock Latch Mechanism for Deutz-Fahr DX, AgroPrima, AgroStar & AgroXtra Tractors - Part Number: 65404013
The heavy-duty right-hand (RH passenger-side) cab door lock latch mechanism (part number 65404013, genuine Deutz-Fahr OEM references 04357782/10+04339586/10, 04357782100433958610, 04339586/10, 04357782, 04357782/10, right-hand counterpart to 65404012) is an authentic OEM-grade door closure and capture assembly designed for panoramic and soundproof cabin enclosures (such as StarCab and MasterCab) on Deutz-Fahr agricultural tractors. Fabricated with a heavy-gauge stamped steel housing protected by an anti-corrosion galvanized coating, it features a progressive dual-stage rotary safety catch system with calibrated linkage sockets for external handles and interior release levers. Built strictly to original equipment tolerances, it delivers uniform perimeter clamping pressure against the right door weatherseal, preventing cab rattles, wind noise, draft ingress, exhaust fumes, and fine field dust contamination. It offers direct plug-and-play fitment across widespread Deutz-Fahr tractor lines (AgroPrima, AgroStar, AgroXtra, DX, DX 3, DX 4, DX 6, and DX 7 series).
Key Features & Engineering Advantages
- Two-Stage Positive Rotary Safety Catch: Progressive two-position latching cycle (initial capture and full lock) prevents accidental door unlatching under harsh field vibration, engine harmonics, and rough terrain haulage.
- Direct Deutz-Fahr Cab Frame Fitment (RH Side): Mounting hole centers, backset, and linkage pivot points strictly conform to original Deutz-Fahr right-hand cab door profiles, ensuring seamless bolt-on fitment without drilling, slotting, or rod alterations.
- Anti-Corrosion Tropicalized Zinc Plating: Rugged metallic casing and internal pivot pins resist oxidation, moisture, acidic agrochemicals, mud, and high-pressure steam cleaning.
- High-Tensile Internal Return Spring Pack: Calibrated spring pack delivers crisp, low-effort handle return, eliminating handle rattle, sag, and sticky mechanical actuation from both inside and outside the cab.
- Superior Cab Acoustic & Environmental Sealing: Applies uniform clamping force against the perimeter rubber door seal of the right-hand door, preserving cabin soundproofing and ventilation efficiency.

Installation Advice & Workshop Notes: Before installation, dismantle the interior door trim panel on the RH door to reveal the latch pocket, and carefully unclip the linkage rods linking the exterior handle and the inside release mechanism. Unbolt the mounting fasteners from the door profile and remove the old latch unit. Position the new 65404013 latch mechanism, reconnect all operating linkage rods, and verify that they actuate freely without bending or binding. Tighten mounting screws securely, then align the striker pin on the cab B-pillar: the door should catch cleanly on the initial safety catch and close into the full lock position with moderate pressure, fully compressing the perimeter rubber seal. Periodically lubricate internal moving pawls and pivot points with white lithium grease or water-resistant PTFE spray.
