Key Features of This Cummins Onan RV Generator Maintenance Kit
Genuine Cummins Onan Replacement Parts
This package contains genuine Cummins Onan replacement parts identified by the supplied part numbers. Check each number against your generator’s documentation before purchasing to confirm that the components are appropriate for your application.
Air Filtration, Oil Filtration, and Ignition Service
The kit brings together an air filter, an oil filter, and two spark plugs. These components support different aspects of routine engine maintenance: airflow, oil filtration, and ignition. Replacing service parts at the intervals specified in your operator’s manual helps you follow the recommended maintenance schedule.
Four Components in One Package
With four individual components included, this maintenance kit provides several commonly replaced items in one package. It can be a practical option when your scheduled service requires all the listed parts and the kit has been confirmed as compatible with your generator.
Suitable for Routine Generator Maintenance
Regular maintenance helps keep a generator serviced according to its manufacturer’s instructions. Always use the correct replacement components, follow the prescribed service intervals, and consult the operator’s manual for the procedures applicable to your specific model.
Cummins Onan 5500 and 7000 RV Generator Compatibility
This maintenance kit is intended for select gasoline-powered RV generator applications, including:
- Select Cummins Onan 5500-watt gasoline RV generators.
- Select Cummins Onan 7000-watt gasoline RV generators.
- Select HGJAA, HGJAB, HGJAC, and HGJAE applications.
- Select Marquis Gold and RV QG models.
These are application families, not a guarantee that every generator within a listed family uses the same service components. Compatibility may vary according to the complete model number and specification letter.
Please verify before ordering: Compare the full model and specification information on your generator identification label with the operator’s manual and the original air filter, oil filter, and spark-plug part numbers. If you are unsure, confirm compatibility with a qualified parts supplier before purchasing.
HGJAA identifies a generator model family; it is not the maintenance kit’s part number. The listed component numbers are 140-3116, 122-0836, and 167-1638.
Installation and Generator Maintenance Safety
Follow the manufacturer’s maintenance instructions when servicing your RV generator. Before beginning maintenance:
- Allow the generator to cool completely.
- Disconnect its starting battery before maintenance.
- Consult the operator’s manual for the correct service procedure.
- Confirm that each replacement component matches the generator’s complete model and specification.
- Follow the manufacturer’s recommended replacement intervals and installation instructions.
Do not begin servicing a hot generator or use a replacement component solely because its appearance or general application seems similar. If you are unsure how to complete a service procedure safely, consult a qualified technician.
Why Choose This Cummins Onan Maintenance Kit?
