Wacker Neuson 5000186917 Lynch Pin (Cylinder/Mount Pin)

The Wacker Neuson Lynch Pin (Cylinder/Mount Pin) is a genuine OEM component designed for Wacker Neuson Hydraulic Thumb attachments. As an authorized OEM part, it is manufactured to the exact specifications required for proper installation and long-term function on compatible Hydraulic Thumb units. Sourced directly through the Wacker Neuson parts network, ensures you are fitting the correct pin the first time. This is the same part used in original equipment assembly, making it a straight swap with no guesswork.

Key Features

• OEM-Grade Pin Material — Manufactured to Wacker Neuson's original dimensional and material tolerances, ensuring the pin seats and locks correctly under hydraulic load and repeated cycling.
• Drop-In Installation — Engineered to align directly with the cylinder and mount pin bores on compatible Hydraulic Thumb attachments, slotting and securing without modification.
• Confirmed Hydraulic Thumb Fitment — Compatible with Wacker Neuson Hydraulic Thumb attachment models 5000176273 and 5000176407.
• Retains Cylinder and Mount Pin Under Load — A functioning lynch pin locks the cylinder and mount pin in place during operation; a worn or missing pin risks pin walk-out and loss of thumb control at the worst possible moment.
• Genuine Wacker Neuson Part — Supplied as a genuine OEM replacement, giving you full confidence in part identity and traceability when servicing attachment hardware.

A lynch pin is a small but critical fastener used to retain a cylinder or mount pin in position within an attachment linkage. On a hydraulic thumb, it passes through or clips around the end of the pivot pin to prevent it from drifting or ejecting during movement and gripping cycles. Without a properly seated lynch pin, the main pin can work loose under vibration and load, leading to unwanted play in the thumb, accelerated wear on surrounding components, or a complete loss of thumb articulation mid-task.
