The Bomag 05744846 Piston with Piston Rings is a genuine OEM component designed for the BP 18/45 D-2 vibratory plate, BPR 30/38 D-3 reversible vibratory plate, and BT 80 D tamper. Sourced directly from Bomag, this part delivers the exact dimensions and ring geometry your engine requires for proper compression and long-term performance. This piston assembly is a direct replacement for the worn or damaged original, covering three distinct Bomag machine families with a single part number 05744846.
Key Features
- Genuine OEM Compression Integrity — machined to Bomag's exact bore diameter and ring-groove tolerances, ensuring the piston seals correctly against the cylinder wall and maintains rated compression
- Complete Piston Assembly — supplied with piston rings already included, so installation is straightforward with no need to source rings separately
- Broad Bomag Fitment — fits the BP 18/45 D-2 vibratory plate, BPR 30/38 D-3 reversible vibratory plate, and BT 80 D tamper, making this a versatile stock item for mixed Bomag fleets
- Restored Engine Output — a worn piston or damaged rings causes loss of compression, hard starting, and excessive oil consumption; this replacement restores full engine power and efficiency
- Fuel System Safety — correct piston-to-cylinder clearance prevents blow-by gases from contaminating the crankcase and fuel system, protecting downstream engine components
The piston is the reciprocating component inside the engine cylinder that converts combustion pressure into mechanical force. The piston rings seated in its grooves seal combustion gases above the piston, scrape excess oil from the cylinder wall, and transfer heat away from the piston crown into the cylinder. When the rings wear or the piston itself is scored or cracked, compression drops sharply — the engine becomes difficult to start, runs roughly, and burns oil. Replacing the piston and rings as a matched set with genuine OEM part number 05744846 restores the tight seal the engine needs to deliver full compaction force to the vibratory plate or tamper.
