The Multiquip 91201ZE9003 is a genuine OEM Oil Seal 8X14X5 designed for GX340 and GX390K1 Honda-engined equipment across multiple Multiquip product families. This seal is engineered to OEM specification, ensuring a correct fit and consistent sealing performance in the applications it was built for. Compatible models include the MVH408GH and MVH304GSB plate compactors, MRH800GS walk-behind roller, AR13H, AR13HA/HAR, and AR13HC asphalt ride-on rollers, and GA6HB, GA6HEB, and GA9.7HE gasoline-powered generators. When you need a direct OEM replacement, part number 91201ZE9003 is the correct part to order.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to exact dimensional tolerances (8x14x5 mm) for the GX340 and GX390K1 engine family, ensuring full compression and leak-free performance at the sealing surface.
- Direct OEM Replacement — Seats into the original bore without rework; the seal lip profile and material match the original Honda engine specification for this part position.
- Broad Multi-Family Fitment — Confirmed for MVH408GH, MVH304GSB, MRH800GS, AR13H series, GA6HB, GA6HEB, and GA9.7HE — one part number serving plate compactors, walk-behind rollers, ride-on rollers, and generators.
- Prevents Oil Loss and Contamination — A worn or failed oil seal allows engine oil to escape the crankcase and permits dirt ingestion, accelerating internal wear and leading to premature engine failure.
- Fuel System and Engine Safety Compliance — Maintaining an intact oil seal is critical to correct crankcase pressure balance; a failing seal can affect oil starvation conditions and create fire risk from oil contact with hot engine surfaces.
An oil seal is a precision-fit ring that closes off a rotating shaft opening in an engine housing, preventing lubricating oil from escaping while keeping contaminants out. In GX340 and GX390K1 Honda engines, the crankshaft oil seal sits where the crankshaft exits the engine case and is subject to constant rotational friction and heat. When this seal deteriorates or cracks, oil leaks past the shaft, the engine loses lubrication pressure, and dirt can work its way into the crankcase — both conditions shorten engine life significantly. Replacing the seal at first sign of leakage is one of the most cost-effective engine maintenance steps available.
