Wacker Neuson 5000192431 Pin Retainer Extension Bolt

The Wacker Neuson Pin Retainer Extension Bolt is a genuine OEM component designed for Wacker Neuson Hydraulic Thumb attachments. Sourced directly from Wacker Neuson, this part meets the exact material and dimensional standards of the original — so you can install it with confidence and get the attachment back to work without second-guessing fitment. It is confirmed compatible with Hydraulic Thumb models and.

Key Features

• OEM-Grade Retention Strength — Manufactured to Wacker Neuson's original torque and shear specifications, ensuring the bolt holds the pin retainer securely under the dynamic loads typical of hydraulic thumb operation.
• Drop-In Installation — Matches the original thread pitch, length, and head profile exactly, so it seats and torques to spec without any modification to the attachment hardware.
• Confirmed Hydraulic Thumb Fitment — Verified for Wacker Neuson Hydraulic Thumb attachments, covering models 5000176274 and 5000176407.
• Keeps the Pin Retainer Locked in Position — A worn or missing extension bolt allows the retainer to shift or back out, putting the thumb's pivot pin at risk of walking free during operation — this replacement restores that critical hold.
• Genuine Wacker Neuson Part — Carries the Wacker Neuson OEM designation, meaning part number 5000192431 is the same component supplied on the original attachment build — no substitutions, no guesswork.

A pin retainer extension bolt secures the retainer clip or collar that locks the pivot pin in place on a hydraulic thumb attachment. Without it, the retainer cannot be properly fastened, leaving the pin free to drift under the repeated shock loads of gripping and releasing material. Over time, a loose or absent bolt leads to accelerated wear on the pin bore and can result in unplanned disassembly of the thumb mechanism mid-shift.
