The Wacker Neuson Cylinder Head Complete is a genuine OEM component designed for a broad range of Wacker Neuson diaphragm trash pumps, dewatering pumps, and vibratory plate compactors. This is a direct OEM replacement sourced through the Wacker Neuson parts program, ensuring the assembly meets the original engineering specifications for every machine it serves. Compatible models include the PDT2 and PDT3 diaphragm trash pumps, PDI2 and PDI3 diaphragm trash pumps, PG2 and PG3 dewatering pumps, and the VP1135R, VP50X, and VP60X vibratory plate compactor families.
Key Features
- Genuine OEM Assembly — Manufactured to Wacker Neuson's original combustion and compression specifications, ensuring correct chamber geometry and head sealing integrity for this engine application.
- Complete Head Assembly — Supplied as a fully assembled cylinder head unit, so installation proceeds without sourcing separate valves, springs, or retainers individually.
- Wide Cross-Model Fitment — Confirmed fit across the PDT2, PDT3, PDI2, PDI3, PG2, PG3 pump series and VP1135R, VP50X, and VP60X vibratory plate compactor families — one part number covering multiple machines.
- Restored Engine Compression — A worn or cracked cylinder head causes compression loss, hard starting, and power drop. Replacing with part 5000205112 restores proper compression and full engine output.
- Fuel System Safety — Correct head sealing prevents combustion gas leakage and fuel vapour ingress into the crankcase, which is critical for safe operation of fuel-powered pumps and compaction equipment.
The cylinder head seals the top of the engine's combustion chamber, housing the intake and exhaust valves that control the flow of air and fuel into — and exhaust gases out of — the cylinder. It works together with the head gasket and cylinder bore to build and maintain the compression pressure the engine needs to fire reliably and produce rated power. When the cylinder head cracks, warps, or develops valve seat wear, the engine loses compression, idles roughly, and struggles to reach working speed — causing the pump or compactor to underperform or fail to start altogether. Replacing a damaged head with the correct OEM assembly restores combustion efficiency and returns the machine to full operating condition.
