Bomag 05815838 Piston Kit

The Bomag 05815838 Piston Kit is a genuine OEM replacement designed for a broad range of Bomag single drum rollers, tandem rollers, pneumatic tyred rollers, and recycler/stabilizers. This piston kit delivers the exact geometry and material grade required to restore engine compression and performance across compatible machines, including the BW 172 D-2, BW 212 D-2, BW 202 AD-2, BW 184 AD, BW 12 R, MPH 364-2, and RS 360 TIER-4F. As a genuine Bomag OEM part, the part is manufactured to the same standards as the original component it replaces, ensuring a correct fit with no guesswork. Sourced directly through DHS Equipment, this kit is the right choice when rebuilding or overhauling engines on any of the covered models.

Key Features

• Genuine OEM Compression Integrity — manufactured to Bomag's original piston specifications, maintaining the precise bore tolerances and ring land geometry critical for correct compression and engine efficiency
• Direct-Fit Replacement — this kit is engineered to install directly in place of the original piston assembly, with matched dimensions for the cylinders on all covered Bomag machines
• Wide Fitment Coverage — compatible with BW-series single drum rollers including the BW 142 D-2, BW 172 D-2, and BW 212 D-2; tandem rollers including the BW 141 AD-2, BW 151 AD-2, BW 202 AD-2, and BW 202 AHD-2; the BW 12 R pneumatic tyred roller; and recycler/stabilizers including the MPH 364-2 and RS 360 TIER-4F
• Engine Rebuild Confidence — a worn or damaged piston causes loss of compression, increased oil consumption, and rough running; replacing it with this kit restores proper power output and smooth operation
• Fuel System and Emissions Compliance — correct piston fit is essential to maintaining proper combustion chamber sealing, which directly affects fuel efficiency and exhaust emissions compliance on tier-rated engines such as the RS 360 TIER-4F

A piston kit contains the core internal engine components — typically the piston itself, piston rings, and related hardware — that seal combustion gases inside the cylinder and transfer the force of combustion to the crankshaft. When pistons or rings wear, the engine loses compression, burns oil, and delivers reduced power, putting the productivity of your roller or stabilizer at risk. Installing a fresh piston kit restores the tight cylinder seal the engine needs to run at full output and operate efficiently across demanding compaction and stabilization work cycles.
