The Bomag 05748120 Insulator Gasket is a genuine OEM component designed for BW 900 AD tandem rollers and BW 900-2 walk-behind rollers. Sourced directly from Bomag, this insulator gasket delivers an exact match to the original part, ensuring a proper seal without rework or adjustment. Whether you're servicing a BW 900 AD or a BW 900-2, part number 05748120 is the correct OEM replacement for restoring airtight, vibration-damped integrity to the engine's intake or exhaust interface.
Key Features
- Genuine OEM Sealing Integrity — manufactured to Bomag's original material and compression specifications, so the gasket seals under the same thermal and mechanical loads as the part it replaces
- Direct Bolt-On Fitment — matches the original mounting pattern and port dimensions exactly, dropping into place without trimming or custom fitting
- Confirmed Compatibility — verified fit for the BW 900 AD tandem roller and the BW 900-2 walk-behind roller
- Heat and Vibration Resistance — insulator gasket construction dampens engine vibration transfer and resists heat-induced degradation, maintaining a consistent seal over extended service intervals
- Fuel and Emissions System Integrity — a failed or cracked insulator gasket can introduce unmetered air into the fuel-air path, affecting engine tuning and exhaust integrity; replacing it promptly keeps combustion and emissions performance on spec
An insulator gasket sits between the engine's carburetor or intake manifold and the cylinder head, creating a sealed, thermally insulated interface that prevents heat from the engine from transferring into the fuel-air mixture before combustion. It also absorbs vibration between mated components, reducing stress on the carburetor mounting studs and connected fuel lines. When an insulator gasket cracks, hardens, or compresses unevenly, the resulting air leak disrupts the fuel-air ratio, causing rough idling, hard starting, and reduced engine performance — making timely replacement essential to keeping the compactor running smoothly.
