The Wacker Neuson Dowel Pin is a genuine OEM component designed for G40 and G50 series portable generators. Sourced directly from Wacker Neuson, this part carries the same specification as the original installed at the factory, ensuring a correct, no-guesswork installation. Confirmed fitment spans multiple G40 configurations — including mobile and stationary variants — as well as the G50 generator series.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the exact diameter and length tolerances required for proper seating and alignment in the generator assembly.
- Direct Drop-In Replacement — Matches the original pin profile, so it installs into existing bores without reworking mating components.
- Broad G-Series Fitment — Compatible with G40 (standard, mobile, and LATAM Premium configurations) and G50 generator models.
- Alignment Integrity — A correctly seated dowel pin keeps mating components precisely located; a worn or missing pin allows shift and fretting that can accelerate wear across connected parts.
- Verified Wacker Neuson Part Number — Part number 5200021088 is confirmed against Wacker Neuson OEM parts data, giving you confidence you are ordering the right component the first time.
A dowel pin is a precision locating fastener used to fix the exact position of two mating components relative to each other. Unlike a bolt, which clamps parts together, a dowel pin resists lateral movement and keeps surfaces in precise alignment under load and vibration. In a portable generator, correctly positioned internal components are critical to mechanical integrity and long service life — a missing or damaged dowel pin can allow components to shift, leading to accelerated wear, misalignment, and potential damage to surrounding parts.
