The bypass valve allows oil to continue flowing during cold starts or if the filter becomes restricted, helping prevent oil pressure starvation that can damage gaskets and engine components.

Installation & Maintenance Notes
For Cummins Onan RV QG 5500/7000 series generators using the 122-0836 oil filter, general service steps include:
- Run the generator briefly to warm the oil, then shut down and allow it to cool before servicing.
- Drain engine oil per the generator’s operator manual before removing the old filter.
- Use the Onan filter wrench (420-0577) or an appropriately sized filter wrench to remove the old filter.
- Lightly oil the new gasket with clean engine oil before installing the new 122-0836 filter.
- Hand-tighten per manufacturer torque specification — avoid over-tightening, which can damage the gasket seal.
- Refill with the correct engine oil grade and quantity, then check for leaks after startup.
- Recommended replacement interval: every 150 operating hours, or per your generator’s operator manual.
FAQ
Q: Is the 122-0836 compatible with all Onan QG 5500/7000 generators? A: The 122-0836 fits Onan HGJAA, HGJAB and HGJAC models (Spec A through K), covering Marquis Gold/RV QG and Marquis Platinum QG EFI generators. Confirm your generator’s exact model and spec letter before ordering.
Q: What does the bypass valve do? A: The bypass valve allows oil to continue flowing to the engine during cold starts or if the filter element becomes clogged, preventing oil pressure starvation. Filters without a bypass valve can trap debris and lead to high oil pressure, failed gaskets, or engine damage under these conditions.
Q: Can I use a Fleetguard LF16165 instead of the 122-0836? A: Yes — Onan’s own documentation identifies the Fleetguard LF16165 as an approved substitute for the 122-0836, so it is fully compatible with the intended application.
Q: Can I order the 122-0836 with custom packaging or private label? A: Yes. IXIN supports customized packaging, labeling and media specifications for distributors and private-label buyers. Contact our sales team with your requirements.
Q: What is the minimum order quantity (MOQ)? A: MOQ varies by customization level. Get in touch with us via WhatsApp or email for current MOQ and lead time on the 122-0836 oil filter.
