122-0833 Spin-on Oil Filter for RV QD Diesel Generator HDKAH HDKAK

The RV QD 3200, the QD 6000 and 8000 series, and the QD 10000 and 12500 series with HDKAH or HDKAK engines, plus the HQD series HQDPA and HQDPC models and older HDKBA diesel generators.

Every 150 running hours or once a year, whichever comes first. A generator that sits idle still ages the media, which is why the calendar limit applies even on a set with low hours.

Yes. The filter is a full-flow spin-on with a bypass valve that opens when the oil is too thick at a cold start, or when the media has loaded up. Oil keeps reaching the bearings instead of being blocked at the filter.

It cross-references PF1127, B179, LF3591, PH3593A, AM101378, ML 1002 and 51064. Any of those numbers on the old filter confirms the match.

The filter is 76.7 mm (3.02 in) in outside diameter and 86.1 mm (3.39 in) tall, and weighs 300 g. Check the clearance under the filter head on a tight installation before ordering.
