The Bomag 05901419 Piston is a genuine OEM component designed for Bomag MPH and RS-series recycler/stabilizers, including the MPH 121, MPH 122, MPH 122-2, MPH 125, MPH 364-2, MPH 600, MPH 600 3B/4i-PB, MPH 600 EU-FLEX, RS 360 TIER-4F, and RS 650. Sourced directly from Bomag, this piston meets the exact tolerances and material standards specified for these machines. When a worn or damaged piston is left in service, it compromises compression, accelerates engine wear, and can lead to costly mechanical failures — making a like-for-like OEM replacement the straightforward choice for maintaining machine output.
Key Features
- OEM-Spec Compression Integrity — manufactured to Bomag's exact bore diameter and ring-groove tolerances, ensuring correct compression and combustion efficiency in your recycler/stabilizer's engine
- Direct Swap Fitment — engineered to install into the original cylinder bore without machining or modification, matching the factory piston profile and pin dimensions precisely
- Broad MPH and RS-Series Coverage — fits MPH 121, MPH 122, MPH 122-2, MPH 125, MPH 364-2, MPH 600, MPH 600 3B/4i-PB, MPH 600 EU-FLEX, RS 360 TIER-4F, and RS 650 recycler/stabilizers
- Sustained Power Delivery — a correctly fitted piston maintains the cylinder pressure needed to drive the full cutting and mixing output these stabilizers are built to deliver
- Genuine Bomag Part — supplied under Bomag part number 05901419, backed by the full OEM supply chain for traceability and quality assurance
The piston is a core reciprocating component inside the engine cylinder, transferring the force of combustion to the crankshaft via the connecting rod. It must maintain a precise seal against the cylinder wall to hold compression and control oil consumption — roles that depend entirely on correct dimensional tolerances and material hardness. When a piston wears, scores, or cracks, the result is lost compression, increased oil burning, rough running, and ultimately engine damage that can sideline a recycler/stabilizer during critical stabilization or pavement rehabilitation work.
