IMPORTANT:
Oil pump for Cummins 8.3L family — fits QSC 8.3, ISC 8.3, 6CT, and 6CTA variants across on-highway trucks (Peterbilt, Kenworth, Freightliner) and off-highway (Case IH MX210-MX285 tractors, marine, industrial). Alt number: 5449240.

On Case IH tractors, replacement requires front cover removal — budget 6-8 hours (fan drive, damper, front cover). This is a gear-type pump with built-in pressure relief valve. Failure symptoms: low idle pressure below 10 PSI hot, erratic pressure fluctuation with throttle, or excessive high-RPM pressure (stuck relief valve). If seeing high pressure symptoms, inspect relief valve before condemning pump.
