The Multiquip 12358ZJ1000 Breather Cover Gasket is a genuine OEM component designed for GA9.7HE gasoline-powered generators and AR13H, AR13HA, AR13HAR, and AR13HC asphalt ride-on rollers. As a factory-sourced part, it delivers an exact material match to the original gasket, ensuring a proper seal at the breather cover on GX610 Honda engines used across these units. DHS Equipment stocks this part to keep your equipment running without extended sourcing delays.
Key Features
- OEM Material Match — Factory-spec gasket material provides the correct compression and sealing properties at the breather cover, preventing oil vapor leaks and maintaining crankcase pressure balance.
- Direct Drop-In Replacement — Engineered to seat flush against the breather cover housing on GX610 Honda engines, allowing straightforward installation without trimming or modification.
- Broad Fitment Across MQ Equipment — Confirmed for GA9.7HE generators and the AR13H, AR13HA, AR13HAR, and AR13HC ride-on roller series — one part number covers multiple machines in your fleet.
- Crankcase Integrity — A functioning breather cover gasket keeps oil mist contained within the breather system; a compromised gasket leads to external oil seepage, contamination, and accelerated engine wear.
- Fuel and Oil System Compliance — Correct sealing at the breather cover is essential to maintaining proper crankcase ventilation, which directly affects fuel mixture quality and emission compliance on gas-powered equipment.
The breather cover gasket seals the joint between the engine's breather cover and the crankcase, allowing controlled ventilation of blow-by gases while preventing oil from escaping the engine. On Honda GX610 engines, this gasket plays a direct role in maintaining the correct internal pressure environment — if it deteriorates or fails, oil can seep past the cover, leading to external contamination and potential engine damage over time. Replacing a worn breather cover gasket promptly is a straightforward maintenance step that protects the long-term health of the engine.
