Multiquip 820150 Rocker Cover Gasket

The Multiquip 820150 Rocker Cover Gasket is a genuine OEM rocker cover gasket designed for the AR13D asphalt ride-on roller. Sourced directly from Multiquip, this part meets the same specifications as the gasket installed at the factory, ensuring a correct seal between the rocker cover and cylinder head on Vanguard-powered AR13D units. If you are servicing or rebuilding the top end of your AR13D, verifying you have part number 820150 on hand before you begin will save time and prevent a return trip.

Key Features

• Genuine OEM Seal Integrity — Manufactured to the exact material thickness and compression spec required by the Vanguard engine fitted to the AR13D, ensuring an oil-tight rocker cover seal from day one.
• Direct Drop-In Fitment — Contoured to match the rocker cover mating surface precisely, so the gasket seats flat and torques down evenly without trimming or adjustment.
• Verified AR13D Compatibility — Confirmed fitment for the Multiquip AR13D asphalt ride-on roller; cross-reference part number 820150 against your machine's parts manual before ordering.
• Prevents Oil Leaks at the Valve Cover — A degraded or damaged rocker cover gasket allows engine oil to seep past the cover, creating fire risk, contamination, and accelerated engine wear. Replacing it restores a clean, sealed top end.
• Fuel and Oil Resistant Material — Built from gasket material suited to withstand the heat cycling and oil exposure inherent to a working engine valve cover environment.

The rocker cover gasket forms the sealing layer between the valve (rocker) cover and the top of the cylinder head. Its job is to contain engine oil that lubricates the rocker arms and valve train components inside the cover. Over time, heat cycling causes the gasket to compress, harden, or crack, allowing oil to escape down the outside of the engine block. Left unaddressed, a leaking rocker cover gasket can foul ignition components, create a fire hazard near hot exhaust surfaces, and lead to low oil conditions that damage internal engine parts. Replacing the gasket during any top-end service is straightforward and inexpensive compared to the consequences of running with a failed seal.
