Complete maintenance kit containing oil, fuel and air filters plus two spark plugs designed for Onan 5500/7000 and compatible Marquis Gold/Platinum generator models. This RARAYC oil change kit supplies the essential replacement parts to refresh small RV and standby generator engines. The set groups an air filter (140-3116), an oil filter (122-0836), a fuel filter (149-2341-01) and two spark plugs (167-1638), so you can perform a routine service without sourcing individual components. Each item is produced from durable materials to meet typical OEM fit and filtration expectations, helping keep the engine running smoothly between scheduled services.

Which generator models does this kit fit?

This kit is designed for a range of Onan and Marquis generator families used in RV and mobile power applications. Confirm fitment against your engine model codes (HGJAA, HGJAB, HGJAC) and the Onan 5500/7000 series before purchase.

  • Compatible with Onan 5500 and 7000 series generators.
  • Fits Marquis Gold/RV QG and Marquis Platinum QG EFI models.
  • Supports HGJAA, HGJAB, HGJAC engine code variants.
  • Contains OEM-referenced part numbers for verification: 140-3116, 122-0836, 149-2341-01, 167-1638.

What parts are included and why they matter?

The kit bundles the core consumables for a standard oil-change/inspection service to address combustion, intake and fuel delivery needs. Replacing these parts together reduces the chance of a single weak component undermining the service.

  • Air filter 140-3116 — removes dirt and particulates from intake air.
  • Oil filter 122-0836 — captures metal particles and contaminants from lubricating oil.
  • Fuel filter 149-2341-01 — prevents debris and water from reaching the fuel system.
  • Spark plugs 167-1638 (x2) — restore ignition reliability and consistent firing.

How do these components affect generator performance?

Fresh filters and plugs help the generator run more consistently by maintaining proper airflow, fuel cleanliness and ignition. While they don't increase power output, they reduce strain on internal parts and support steady operation under load.

  • Cleaner air helps the engine maintain correct air-fuel mixture.
  • Clean oil reduces wear on bearings and moving parts.
  • Filtered fuel minimizes clogging and injector/carburetor issues.
  • New spark plugs improve start-up and smooth combustion cycles.

What should I check before installing this kit?

Verify the generator model, engine code and part numbers to ensure compatibility; also inspect service manuals for recommended service intervals and correct installation steps. If you're unsure, compare the included OE numbers to existing components or consult a technician.

  • Match model and engine codes: Onan 5500/7000, HGJAA/B/C, Marquis Gold/Platinum QG.
  • Confirm OE numbers: 140-3116, 122-0836, 149-2341-01, 167-1638.
  • Gather basic tools and replacement oil per your manual before starting.
  • Dispose of used oil and filters responsibly according to local regulations.
Who is this for?

This RARAYC kit is aimed at RV owners, fleet managers and service technicians who perform routine maintenance on Onan 5500/7000 and compatible Marquis generator engines. It’s a convenient option for anyone who prefers a single parts purchase that covers intake, fuel, oil and ignition items during a scheduled service, saving time sourcing matched components.

FAQ

Q: Are these OEM parts or aftermarket replacements?

A: These are aftermarket replacement parts matched to OEM reference numbers for fit and function with listed Onan/Marquis models.
