Cabin Door Release Push-Button for Deutz-Fahr AgroPrima, AgroStar, AgroXtra & DX 3 Series Tractors - Part Number: 65404080
The heavy-duty cabin door unlatching push-button (part number 65404080, genuine Deutz-Fahr OEM reference 04356497 / 4356497) is an authentic OEM-grade mechanical actuating component engineered to operate the mechanical door latch mechanisms (compatible with LH latch 65404012 and RH latch 65404013) on Deutz-Fahr tractor cabins (such as StarCab and MasterCab). Manufactured from high-density, UV-stabilized structural polymer with an integrated heavy-duty steel return spring and key cylinder barrel cavity, it delivers smooth, crisp, and low-effort door unlatching free of sticking or binding in demanding agricultural environments. Built strictly to factory tolerances, it integrates seamlessly into the original door handle housing, restoring positive kinematic travel and preventing dust, water, and vibration ingress. This OEM-equivalent component delivers direct plug-and-play fitment across Deutz-Fahr AgroPrima, AgroStar (standard and Freisicht), AgroXtra, and DX 3 series tractors.
Key Features & Engineering Advantages
- Factory-Accurate Deutz-Fahr Fitment: Engineered to match the mounting recess, barrel guide, and linkage engagement points of original Deutz-Fahr cab door handles without modification.
- High-Impact & UV-Resistant Structural Polymer: Molded casing designed to withstand extreme thermal variations (-30°C to +80°C), intensive sunlight exposure, agrochemicals, diesel fuel, and regular high-pressure washdowns.
- High-Resilience Internal Return Spring: Heavy-duty internal spring provides immediate return to the flush position, eliminating sticking, free play, or partial latch disengagement.
- Ergonomic Tactile Contact Face: Sizable push surface designed to offer reliable tactile grip and effortless operation even when working with thick winter gloves or in wet field conditions.
- Direct OEM Replacement: Replaces cracked, worn, or sticking release buttons directly without requiring replacement of the complete handle assembly or door linkage rework.

Installation Advice & Workshop Notes: Prior to installation, dismantle the interior door pillar trim or cover to access the rear of the handle and button housing. Carefully release the retaining pin or clip holding the old button in place and disconnect the actuator tip from the door latch linkage rod (65404012 on LH or 65404013 on RH). Clean the button sleeve of dirt, dust, and dried grease before seating the new 65404080 button, ensuring the internal return spring is aligned straight within its guide. Reconnect the actuator linkage rod and adjust its length so that the button maintains 1–2 mm of free play before contacting the latch lever. Test the push action with the door both open and latched to ensure instant release and immediate return flush with the handle body.
