The Wacker Neuson 5100049559 is a genuine OEM Set of Piston Rings designed for the BPS1030A, BPS1135A, BPS1340A, and VP1135A series single-direction vibratory plate compactors. Sourced directly from Wacker Neuson, this set delivers exact dimensional tolerances and material specifications required by the original engine design. The 5100049559 covers an extensive range of BPS variants including A, Aw, and Aws configurations across standard, US, and EU editions, making it a versatile engine rebuild component for fleet operators and service technicians alike. Confirm your machine's model number before ordering to ensure the correct fit for your specific compactor configuration.
Key Features
- Genuine OEM Ring Tolerances — Manufactured to Wacker Neuson's original bore and compression specifications, ensuring proper ring gap, tension, and sealing performance within the cylinder.
- Full Set Included — Supplies all piston rings needed for a complete ring replacement service, simplifying the rebuild process and reducing the chance of mixing mismatched components.
- Broad BPS and VP Series Coverage — Fits BPS1030A, BPS1030Aw, BPS1135A, BPS1135Aw, BPS1340A, BPS1340Aw, BPS1340Aws, and VP1135A plate compactors across standard, US, and EU variants.
- Restored Compression and Oil Control — Worn piston rings cause loss of compression, increased oil consumption, and reduced compaction force; a fresh set restores full engine output and sealing integrity.
- Direct Engine Rebuild Component — Designed to drop into the original cylinder bore without machining or fitment adjustments when used as part of a standard overhaul procedure.
Piston rings sit in grooves around the piston and serve two critical functions: sealing combustion gases above the piston to maintain compression, and controlling oil film on the cylinder wall to prevent excessive consumption. On a vibratory plate compactor like the BPS and VP series, consistent engine compression is directly tied to the centrifugal clutch engagement and the vibration output that drives compaction performance. When piston rings wear, become stuck, or lose tension, compression drops, the engine runs rough or loses power, and oil burns off at an accelerated rate — signs that a ring set replacement is due.
