The Wacker Neuson 5100026382 Intake Valve Seat is a genuine OEM component designed for DPU80 and DPU90 series reversible vibratory plate compactors. Sourced directly from Wacker Neuson, this part meets the exact specifications required for correct engine operation across a wide range of DPU80 and DPU90 models, including Lec and Lem engine variants in both standard and reversible configurations. Genuine OEM construction ensures the seat geometry, material hardness, and sealing surface match the original part precisely. Whether you are performing a valve job or rebuilding the engine top end, the 5100026382 is the correct replacement to restore proper compression and engine performance.
Key Features
- Hardened Sealing Surface: — Manufactured to the exact material hardness spec required for consistent valve-to-seat contact, preventing compression loss and blow-by over extended service cycles.
- Genuine OEM Part: — Supplied by Wacker Neuson, this intake valve seat carries the same part number and dimensional tolerances as the component installed at the factory, ensuring a correct drop-in fit during valve service.
- Broad DPU80 and DPU90 Compatibility: — Fits DPU80Lec, DPU80Lem, DPU80rLec, DPU80rLem, DPU90Lec, DPU90Lem, DPU90rLec, and DPU90rLem models, covering both standard and reversible plate configurations.
- Restores Full Engine Compression: — A worn or pitted intake valve seat causes compression leakage, hard starting, and loss of power output. Replacing it with the correct OEM seat brings combustion efficiency back to spec.
- Correct Fit for US-Spec Models: — Explicitly covers DPU90Lec770 US, DPU90Lem770 US, DPU90rLec770 US, and DPU90rLem770 US variants, so North American operators get the right part without guesswork.
The intake valve seat is a precision-machined ring pressed into the cylinder head that provides the mating surface against which the intake valve closes during each engine cycle. A tight, consistent seal between the valve face and its seat is essential for maintaining proper cylinder compression — without it, the engine loses power, becomes difficult to start, and may run rough or overheat under load. Over time, heat cycling and wear can erode or pit the seating surface, making replacement necessary to restore the engine to proper working condition.
