The part is also documented in multiple generator platforms where two DF3800H-31202-A Isolator B components are used within the frame assembly.

Important Notes

• Verify compatibility with your specific generator model, manufacturing number, engine configuration, serial number, and production revision before ordering.
• Homelite OEM parts suppliers identify DF3800H-31202-A specifically as “ISOLATOR B.”
• Factory generator documentation may alternatively identify this component as “Bottom Rubber B.”
• This component is designed to help absorb vibration and reduce vibration transfer within applicable equipment assemblies.
• Some documented generator assemblies specify two DF3800H-31202-A Isolator B components per generator.
• Do not confuse DF3800H-31202-A Isolator B with DF3800H-31201-A Isolator A. They are separate vibration isolation components used together on some generator frame assemblies.
• Do not select a replacement isolator based solely on appearance. Dimensions, rubber hardness, mounting studs, thread sizes, load ratings, and equipment applications can differ between similar-looking mounts.
• Match part number DF3800H-31202-A directly with the number shown in your equipment's illustrated parts diagram or OEM documentation.
• Inspect the associated Isolator A components, frame mounting points, flange nuts, engine/generator mounts, and surrounding hardware when replacing the isolator.
• If the original isolator has split, collapsed, or deteriorated, inspect the other vibration mounts for similar age-related wear.
• Excessive generator vibration can also result from loose mounting hardware, damaged frame components, engine problems, or worn associated isolators.
• Replace cracked, hardened, torn, compressed, distorted, excessively worn, or otherwise damaged related vibration mounts as necessary.
• Install the replacement isolator in the same factory position and orientation as the original component.
• Ensure all applicable mounting hardware is properly secured according to manufacturer specifications.
• Shut down the generator, allow the engine to cool completely, disconnect the spark plug where applicable, and follow manufacturer service procedures before performing repairs.
• This listing is for one Homelite DF3800H-31202-A Isolator B only unless otherwise specified. Isolator A mounts, flange nuts, frame components, engine mounts, hardware, and other generator components are sold separately.
• Match part number DF3800H-31202-A with your generator's illustrated parts diagram or OEM documentation before ordering to ensure proper fitment.
