Right-Hand (RH Passenger Side) Cabin Door Lock Latch Mechanism for Fiat 88 Series Tractors with CS, Komfort & Super Comfort Cabs - Part Number: 65417018
The heavy-duty right-hand (RH passenger-side) cab door lock latch mechanism (part number 65417018, genuine Fiat / FiatAgri OEM references 15843, 5108381) is an OEM-standard mechanical door capture assembly engineered for CS, Komfort, and Super Comfort cabin enclosures on FiatAgri 88 Series agricultural tractors. Built with a heavy-gauge stamped steel housing protected by an anti-corrosion galvanized coating, it features a progressive dual-stage safety rotary catch system, internal spring-loaded locking pawls, and secure linkage sockets for external push handles and interior release levers. This replacement latch ensures uniform perimeter clamping pressure against the RH cab door rubber seal, eliminating field vibrations, door chatter, draft ingress, exhaust fumes, and dust entry into the cab. It provides direct plug-and-play fitment across Fiat tractors (55-88, 60-88, 65-88, 70-88, 80-88 with CS, Komfort, or Super Comfort cabins).
Key Features & Engineering Advantages
- Two-Stage Positive Rotary Safety Catch: Progressive two-position latching cycle (initial capture and full lock) prevents accidental door opening under intense field vibration, chassis flex, and rough haulage conditions.
- Factory-Accurate Fitment for CS, Komfort & Super Comfort Cabs (RH Side): Hole spacing, backset, and casing dimensions strictly conform to original FiatAgri right-hand door profiles, ensuring direct bolt-on replacement without drilling or modification.
- Heavy-Duty Tropicalized Zinc Plating: Rugged metallic housing and internal pivot points resist oxidation caused by high humidity, field mud, chemical fertilizer dust, and pressure washing.
- High-Tensile Internal Spring Pack: Calibrated spring pack delivers smooth, positive handle return, eliminating handle free-play, rattle, and sticky mechanical actuation.
- Superior Cab Acoustic & Environmental Sealing: Applies uniform clamping force against the perimeter rubber door seal of the right-hand door, preserving cabin noise insulation and heating/ventilation efficiency.

Installation Advice & Workshop Notes: Before installation, dismantle the interior door service panel or trim on the RH door to reveal the latch pocket, and carefully unclip the linkage rods linking the exterior push handle and the inside release lever. Unbolt the retaining screws from the door frame profile and remove the old latch unit. Position the new 65417018 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 latch smoothly on the initial 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.
