- Cummins Onan Model HGJBB RV QG Generators
It features a rectangular foam element with a pre-cleaner, engineered for RV applications.
Setup and Installation
Follow these steps to replace your generator's air filter:
- Prepare the Generator: Ensure the generator is turned off, cool, and disconnected from any power source. Locate the air filter housing, typically found near the carburetor or intake manifold.
- Access the Air Filter: Open the air filter housing. This usually involves unlatching clips, unscrewing fasteners, or removing a cover. Refer to your generator's manual for exact instructions.
- Remove Old Filter: Carefully remove the old air filter and pre-cleaner. Note its orientation for correct installation of the new filter. Dispose of the old filter responsibly.
- Clean Housing: Inspect the air filter housing for any debris, dust, or dirt. Clean the housing thoroughly with a damp cloth, ensuring no foreign material enters the carburetor.
- Install New Filter: Place the new Part Synergy air filter (Model 1064-A030Y328) into the housing, ensuring it fits snugly and is oriented correctly. The foam pre-cleaner should be positioned as the outer layer.
- Secure Housing: Close and secure the air filter housing, ensuring all clips or fasteners are properly engaged.
- Final Check: Reconnect any disconnected wires or battery terminals. Start the generator to confirm proper operation.

Operating Considerations
A clean air filter is crucial for the efficient operation of your generator. While the air filter itself is a passive component, its condition directly impacts engine performance:
- Engine Protection: The air filter prevents dust, dirt, and debris from entering the engine's combustion chamber, protecting internal components from wear and damage.
- Optimal Fuel Efficiency: A clean filter ensures proper airflow to the engine, allowing for efficient fuel combustion and maintaining optimal fuel economy.
- Consistent Power Output: Adequate airflow is necessary for the generator to produce its rated power output without strain.
Regularly inspect your air filter, especially when operating in dusty or dirty environments, to ensure it remains clean and functional.
Maintenance
Proper maintenance of your air filter extends the life of your generator and ensures reliable performance.
Inspection Schedule
- Inspect the air filter every 50 hours of operation or every 3 months, whichever comes first.
- In dusty conditions, inspect the filter more frequently (e.g., every 25 hours or monthly).
Cleaning the Foam Pre-Cleaner
The foam pre-cleaner can often be cleaned and reused:
- Remove the foam pre-cleaner from the main filter element.
- Wash the foam in warm water with a mild detergent.
- Rinse thoroughly until all soap residue is gone.
- Squeeze out excess water and allow it to air dry completely. Do not wring or twist.
- Lightly oil the dry foam pre-cleaner with clean engine oil, then squeeze out any excess oil. The foam should be damp with oil, not dripping.
- Reinstall the pre-cleaner over the main filter element.
Filter Replacement
The main air filter element should be replaced when it appears heavily soiled, damaged, or cannot be cleaned effectively. A general guideline for replacement is every 100-200 hours of operation or annually, depending on usage and environmental conditions. Always replace with a genuine Part Synergy filter (Model 1064-A030Y328) for guaranteed compatibility and performance.

Troubleshooting
If your generator exhibits any of the following symptoms, a dirty or clogged air filter may be the cause:
- Reduced Engine Power: The generator struggles to produce its usual power output.
- Increased Fuel Consumption: The engine may run richer to compensate for restricted airflow, leading to higher fuel usage.
- Rough Running or Stalling: Inconsistent airflow can cause the engine to run unevenly or stall.
- Excessive Smoke from Exhaust: A rich fuel mixture due to a clogged filter can result in black smoke.
Solution: Inspect the air filter and pre-cleaner. Clean or replace them as necessary following the instructions in the Maintenance section. If symptoms persist after replacing the air filter, consult your generator's owner's manual or a qualified service technician for further diagnosis.
