149-2513 122-0833 140-2897 Filter Kit for Onan RV QD Generator
A three-filter service kit for the Cummins Onan RV QD and HQD generator: 149-2513 fuel filter, 122-0833 spin-on oil filter and 140-2897 air filter. They are grouped because they come due at the same service, and buying them apart is how one of the three gets skipped. The fuel filter does the water separation, the oil filter is the canister with the bypass valve that keeps oil moving on a cold start, and the air filter is the oval element on the intake.

❓ FAQ
Yes. One fuel filter, one spin-on oil filter and one air filter. The Amazon listing for this ASIN carries a stale Included Components value of air filter and a unit count of 1, which is why the box contents are spelled out here and in the specification table.
Not as a pair. The oil filter and the air filter are only stocked here as part of this three-filter kit. If you have the fuel filter, this kit still leaves you one spare fuel filter rather than a missing one, and that spare is the part that fails first on a QD.
It opens when the oil is thick on a cold start, or when the media is loaded, so oil keeps reaching the bearings instead of being blocked. A filter without one can starve the engine at start-up; that is why the original Onan filter is specified with a valve.
The air filter covers QD HDKAH, HDKAJ, HDKAK and the HQD HQDPA, HQDPC. It is an oval element with steel mesh on both faces, so check the shape of the old element against the new one before you fit it.
Follow the operator manual for the generator, which for most QD units puts the filters on the same service interval. Doing all three at that point keeps the fuel filter from carrying water into the next season.

Description
Product Overview
A three-filter service kit for the Cummins Onan RV QD and HQD generators: 149-2513 fuel filter, 122-0833 spin-on oil filter and 140-2897 air filter. They are grouped because they fall due at the same service, and because buying them separately is how one of the three gets skipped. The fuel filter does the water separation, the oil filter is the canister with the bypass valve that keeps oil flowing on a cold start, and the air filter is the oval element on the intake side.
