Documented applications include:

• Homelite BM903500 Generator
• Homelite BM903600 3600-Watt Generator
• Homelite BM903611 3600-Watt Generator
• Homelite UT903655DA 3,500-Watt Generator

• Generator engine small-block assemblies
• Low-oil monitoring and protection systems
• Equipment originally requiring D245102
• OEM replacement applications requiring DJ168F-18200

The BM903600/BM903611 parts listing specifically identifies DJ168F-18200 as the Switch Assembly (Oil Level), while Black Max BM903655DA documentation lists one DJ168F-18200 switch per applicable engine assembly.

Important Notes

• Verify compatibility with your specific generator model, manufacturing number, engine model, serial number, and production revision before ordering.
• Homelite OEM parts suppliers identify DJ168F-18200 specifically as “SWITCH ASSEMBLY OIL LEVEL.”
• DJ168F-18200 supersedes previous Homelite part number D245102.
• Parts suppliers also cross-list this component for select Homelite, Ryobi, and Ridgid equipment.
• Do not confuse DJ168F-18200 with DJ168F-18200-A. The “-A” version is separately cataloged and is identified in applicable engine documentation as an Oil Sensor Assembly.
• On applicable engine assemblies, the oil-level switch works alongside other electrical and engine-protection components. The related amplifier or alarm component may be a separate part.
• For example, the UT903655DA engine diagram lists DJ168F-18300 Amplifier separately from the DJ168F-18200 oil-level switch.
• A low-oil warning or shutdown condition does not automatically mean the switch has failed. Always verify that the engine contains the correct quantity and type of oil before replacing electrical components.
• Symptoms of a faulty oil-level switch may overlap with wiring, connector, ignition, amplifier, grounding, or other engine-control problems.
• Inspect the switch wiring, connectors, mounting points, oil condition, and associated electrical components during diagnosis.
• Do not bypass or permanently disable an engine's low-oil protection system as a repair for a faulty component.
• Drain or manage engine oil according to the applicable service procedure before removing components that could allow oil to escape.
• Clean the installation area before fitting the replacement switch to prevent dirt or debris from entering the engine.
• Install the replacement switch in the same factory position and orientation as the original component.
• Secure electrical connections and route wiring away from hot surfaces, sharp edges, and moving engine components.
• After installation, refill or verify the engine oil level according to the manufacturer's specifications and check for proper operation.
• Shut down the generator, allow the engine to cool completely, disconnect the spark plug, and follow the manufacturer's service procedures before performing repairs.
• This listing is for one Homelite DJ168F-18200 Oil Level Switch Assembly only unless otherwise specified. Amplifiers, wiring harnesses, connectors, mounting hardware, engine oil, crankcase components, and other electrical parts are sold separately.
• Match part number DJ168F-18200 with your equipment's illustrated parts diagram or OEM documentation before ordering to ensure proper fitment.
