The Wacker Neuson Shim is a genuine OEM component designed for the PT6LT, PT6LS, PT6Y, and PTK6 series 6-inch self-priming centrifugal trash pumps. Sourced directly from Wacker Neuson, this shim delivers the exacting dimensional tolerance required to maintain proper internal clearances within the pump assembly. It fits a wide range of PT6 configurations including trailer-mounted, skid-mounted, and EPA T4-compliant models. When correct shim stack thickness is maintained, the pump runs at peak efficiency and premature wear to rotating components is avoided.
Key Features
- Precision Thickness Control: — Manufactured to OEM dimensional tolerances, ensuring the shim provides the exact clearance spacing the PT6 pump assembly requires for stable, efficient operation.
- Genuine OEM Part: — Supplied by Wacker Neuson as part number 5000079759, this is the same shim used in original production — no substitution or guesswork at installation.
- Broad PT6 Series Coverage: — Compatible across PT6LT, PT6LS, PT6Y, PT6Y EPA T4, PTK6, and their international variants, including trailer-mounted and skid-mounted configurations.
- Protects Critical Pump Clearances: — A worn or missing shim allows axial play to build up in the pump shaft assembly, accelerating wear on the impeller, seal, and housing — correct shimming prevents this.
- Drop-In Fitment: — Matches the original profile and material spec of the factory shim, fitting directly into the existing pump stack without machining or rework.
A shim is a thin, precision-dimensioned spacer used within a pump assembly to set and maintain correct axial clearance between rotating and stationary components. In a trash pump like the PT6 series, the shim controls the gap between the impeller and pump housing, which directly affects priming performance, flow efficiency, and wear rate. When a shim is lost, damaged, or worn beyond spec, the resulting misalignment accelerates deterioration of the impeller and mechanical seal — restoring the correct shim is a fundamental step in any pump rebuild or seal replacement service.
