The Wacker Neuson Cylinder Head Bolt is a genuine OEM cylinder head bolt designed for the DPU5545H and DPU4545H series reversible plate compactors, including DPU5545He, DPU5545Heh, DPU5545Hec, DPU4545He, DPU4545Heh, and DPU4545Hech variants. Sourced directly from Wacker Neuson, this is the exact same part installed at the factory — no substitutions, no guesswork. It fits across a wide range of DPU5545 and DPU4545 model configurations, including US and export variants, giving you confidence that you are ordering the right part for your machine. When cylinder head hardware fails or needs replacing during a top-end service, using the correct OEM specification bolt ensures proper clamping force and a secure, leak-free seal.
Key Features
- OEM-Specified Clamping Strength — Engineered to the exact torque and tensile specification required to maintain proper cylinder head sealing pressure on Wacker Neuson DPU compactor engines.
- Drop-In Thread Compatibility — Matches the original thread pitch, diameter, and length for a direct installation into the existing cylinder head without reworking the bore or mating surface.
- Broad DPU Series Coverage — Fits DPU5545H and DPU4545H model families, including He, Heh, Hec, Hech, and corresponding US and export variants across multiple production runs.
- Protects Head Gasket Integrity — Correct bolt specification ensures even clamping load across the head gasket, preventing warping, compression loss, and coolant or oil intrusion into the combustion chamber.
- Critical Fastener Safety — Cylinder head bolts are torque-critical components; using a correctly rated OEM bolt reduces the risk of bolt stretch, thread failure, or head gasket blow-out under operating load.
A cylinder head bolt secures the cylinder head to the engine block, compressing the head gasket to create an airtight and oil-tight seal around the combustion chamber. These bolts must withstand extreme thermal cycling and combustion pressure, which can cause them to stretch or fatigue over time — particularly after a head removal for service. Installing a worn, incorrect, or under-spec bolt risks uneven clamping force across the head gasket, which can lead to compression leaks, overheating, and costly engine damage. Replacing with the correct Wacker Neuson 5100032123 Cylinder Head Bolt ensures the engine returns to proper operating condition after any top-end repair.
