The Wacker Neuson O-Ring, Oil Gallery is a genuine OEM seal designed for the PTS4V series power trowels. Sourced directly from Wacker Neuson, this O-ring meets the original design specification for the oil gallery passage, ensuring a proper seal every time. It is a direct-fit replacement for PTS4V machines and installs without modification. If you're servicing the lubrication circuit on your PTS4V, verifying you have the correct part number — — before you start keeps the job moving.
Key Features
- OEM-Grade Seal Material — Manufactured to the original compound and durometer specification, so the O-ring compresses and seats the same way as the part it replaces.
- Drop-In Oil Gallery Fit — Dimensioned to seat precisely in the oil gallery groove, requiring no trimming, stretching, or improvisation during installation.
- Confirmed PTS4V Fitment — Verified for PTS4V series power trowels; cross-reference your machine's part number before ordering to confirm the correct application.
- Oil Circuit Integrity — A correctly seated oil gallery O-ring maintains pressure and prevents internal leakage, protecting engine and drivetrain components from oil starvation.
- Genuine Wacker Neuson Part — Supplied as genuine OEM, so the material grade, sizing, and traceability are backed by the original equipment manufacturer.
An oil gallery O-ring seals the passage that routes engine oil to critical lubrication points within the machine. When this seal is intact, oil flows at the correct pressure to bearings, journals, and other moving components. If the O-ring degrades, cracks, or loses its compression set, oil can bypass the gallery, causing pressure drop and inadequate lubrication — leading to accelerated wear or component failure. Replacing a worn oil gallery O-ring at the first sign of seepage is a low-cost step that protects the broader engine assembly.
