The Bomag 05815688 Piston Kit is a genuine OEM component designed for a wide range of Bomag BW-series tandem rollers — including the BW 120 AD, BW 135 AD, BW 138 AD, BW 174 AD, BW 174 AC, and BW 161 AC-5, among others — as well as Bomag BW 1050 T, BW 850 TR, and BW 85 T trench compactors. Sourced directly from Bomag, this kit delivers the exact specifications required to restore proper engine compression and piston function. As a genuine OEM part, it matches the original tolerances and materials used in production, so you can count on a straight-across replacement without guesswork. Whether you are overhauling an engine in a tandem roller or servicing a trench compactor, part number 05815688 is the correct, verified solution.
Key Features
- OEM-Grade Piston Tolerancing — manufactured to Bomag's original compression and dimensional specifications, ensuring proper combustion chamber fit and engine sealing
- Drop-In Engine Replacement — engineered to match the original piston assembly configuration for direct installation without rework or custom fitting
- Wide Tandem Roller Coverage — fits an extensive range of BW-series tandem rollers including the BW 120 AD, BW 125 ACH, BW 125 ADH, BW 131 AD-2, BW 135 AD, BW 138 AD, BW 144 AD-2, BW 151 AC-2, BW 154 AD-2, BW 170 AD, BW 174 AD, BW 174 AC, and many more generation variants, plus BW 1050 T, BW 850 TR, and BW 85 T trench compactors
- Restored Engine Compression — a worn or damaged piston leads to loss of power, increased oil consumption, and rough running; this kit returns the engine to proper operating condition
- Combustion Safety Integrity — correct piston fit is critical to safe combustion pressure management; using a properly rated OEM piston kit reduces the risk of blow-by, overheating, and accelerated cylinder wear
The piston is a core reciprocating component inside the engine cylinder, converting combustion pressure into the mechanical force that drives the machine. It works in conjunction with piston rings and the cylinder wall to maintain compression and control oil consumption. When a piston wears, becomes scored, or fails, the engine loses power, burns oil, and can suffer deeper internal damage if not addressed promptly. Replacing the piston with a correctly specified kit restores proper compression, smooth operation, and engine longevity across the full range of machines this part serves.
