The Multiquip 458010080 Pump Breather is a genuine OEM component designed for MVH308, MVH408, and MVH508 series reversible plate compactors. As a direct factory replacement, this part ensures the hydraulic pump assembly on your MVH-series machine vents correctly, maintaining proper internal pressure balance during operation. Fitment covers diesel, gasoline, and Vanguard-powered variants across the MVH308, MVH408, and MVH508 model families, including DE, GV, GH, and DZ suffix configurations.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original specification, ensuring correct thread pitch, port sizing, and material grade matched to the hydraulic pump assembly on MVH-series reversible plates.
- Drop-In Replacement — Installs directly into the existing pump breather port with no rework; designed to mate with the pump housing exactly as the original component did.
- Broad MVH-Series Fitment — Compatible with MVH308, MVH408, and MVH508 models across DE, GV, GH, and DZ engine configurations, covering a wide range of reversible plate compactor variants in the Multiquip lineup.
- Protects Hydraulic Pump Integrity — A functioning breather prevents pressure buildup and contamination ingress in the pump housing; a failed or clogged breather can cause seal damage, oil leaks, and premature pump wear.
- OEM Part Number Assurance — Part number 458010080 maps directly to the MVH-series hydraulic pump assembly, removing guesswork when sourcing a replacement on multi-engine model variants.
The pump breather is a small but critical venting component mounted on the hydraulic pump housing of reversible plate compactors. Its role is to allow the pump to breathe — equalizing internal air pressure as hydraulic fluid moves and temperatures fluctuate during compaction work — while blocking dust, debris, and moisture from entering the pump. When the breather becomes clogged or damaged, pressure can build inside the pump housing, accelerating seal wear and potentially forcing oil past gaskets. Replacing a worn or blocked breather promptly helps preserve the hydraulic system and keeps the compactor performing at full compaction force.
