The Bomag 05720034 Piston Ring Set is a genuine OEM component designed for a wide range of Bomag vibratory plates and walk-behind rollers, including the BP 18/45 D-2, BP 25/48 D, BP 25/50 D, BP 20/50 D, BP 20/45 D, BP 15/45 D-2, BVP 18/45 D, BPR 25/40 D, BPR 25/45 D-3, BPR 25/50 D, BPR 30/38 D-3, BPR 35/42 D, BPR 35/42 D/H, BPR 35/60 D, BPR 35/60 D/E, BPR 35/60 D/H, BPR 40/60 D, BPR 40/60 D/E, BPR30 /38, and the BW 71 E-2 walk-behind roller. As a genuine Bomag OEM part, this piston ring set is manufactured to the same specifications as the original, ensuring a correct fit and consistent engine performance across every compatible machine. This is the right part when you need to restore engine compression or complete an engine rebuild on your Bomag equipment.
Key Features
- OEM-Matched Ring Dimensions — manufactured to exact bore diameter, ring width, and gap tolerances specified by Bomag, ensuring correct compression and oil-control performance for the engine in these machines
- Direct Engine Replacement — engineered as a set to drop into the engine on compatible Bomag vibratory plates and walk-behind rollers without modification, using the original ring groove geometry
- Broad Fitment Coverage — compatible with BP, BVP, and BPR series vibratory plates including the BPR 35/60 D, BPR 40/60 D, BP 25/50 D, and BP 18/45 D-2, as well as the BW 71 E-2 walk-behind roller
- Compression Restoration — worn piston rings cause loss of power, excessive oil consumption, and hard starting; replacing this set restores the engine's compression seal so the machine delivers full compaction output
- Complete Set Supplied — all rings required for a full piston ring replacement are included, supporting thorough engine rebuilds and reducing the risk of missed components during service
Piston rings sit in grooves around the piston and form a seal between the piston and the cylinder wall. They serve two critical jobs: sealing combustion gases above the piston to maintain compression and power, and controlling the film of oil on the cylinder wall to prevent it from burning off in the combustion chamber. When piston rings wear, gap, or break, the engine loses compression, burns oil, produces smoke, and struggles to develop the power needed to drive the exciter and deliver effective compaction. Replacing the piston ring set restores the engine's sealing integrity and brings the machine back to full working output.
