This piston installs in the cylinder with piston-connecting rod-crankshaft assembly on Wacker Neuson reversible plate compactors, converting combustion pressure into the mechanical force that drives compaction output through the crankshaft and eccentric system.
Part number 5000126913 is the direct Wacker Neuson factory part for this internal engine assembly position. The piston works in conjunction with the connecting rod and crankshaft as an integrated assembly group, meaning correct fitment and condition of this part directly affects how combustion energy is transferred into plate movement. When a piston is worn, scored, or damaged, the engine will typically exhibit reduced compression, increased oil consumption, loss of power under load, or excessive blowby. Replacing the piston with a factory part ensures the bore clearances, ring land dimensions, and material specifications match what Wacker Neuson engineered for these machines.
This part fits the following Wacker Neuson reversible plate compactor models:
Refer to the applicable Wacker Neuson service manual for torque specifications, piston installation orientation, ring gap positioning, and cylinder clearance measurements before installation. Always inspect the cylinder bore, connecting rod bearings, and crankshaft journal condition when servicing this assembly.
Genuine Wacker Neuson OEM part, sold by an authorized dealer.
