What This Pump Does
The N14 lube oil pump is a spur-gear pump driven off the front gear train. It pulls oil from the pan through the suction tube and pushes it through the cooler and filter head to the main gallery. Everything downstream — mains, rods, cam bushings, turbo feed, piston cooling nozzles — depends on this pump holding volume at both idle and rated speed.
This unit is a steel-bodied assembly with a 32-tooth spur gear, built as a direct replacement for the 3803698 pump on Celect Plus engines. Tooth count matters. If your old pump has a different gear, you are looking at a different application and the number on the old casting is the thing to trust, not the engine badge.
Typical service life runs long, but wear does happen: gear-to-body clearance opens up, the gear faces scuff, or debris from a bearing failure scores the pockets. Once clearance grows, the pump still turns but stops making pressure at hot idle. That is the symptom most people are hunting when they land on this number.
Why These Numbers Cross
The Cummins numbers 3609835, 3609832, 3609828, 3074196, 3804633 and 3865153 all trace back to the same lube pump family used on the N14 Celect Plus. Cummins revised the pump over the production run — casting changes, supersessions, and service-kit packaging — so a single physical pump can carry several numbers depending on when and how it was ordered.
PAI 141294 is the aftermarket catalog number for the same assembly. Aftermarket suppliers assign their own numbers and then list the Cummins numbers alongside for identification. That is why one part shows up under eight numbers in a search. They are listed here for cross-reference only; we are not affiliated with or authorized by any OEM.
The practical takeaway: if the number stamped or tagged on your old pump appears in that list, 3803698 is the right starting point. It is a starting point, not a fitment promise. Confirm with your engine serial number or by matching the number on the pump you pulled off.
Before And After Install
Find out why the old pump failed before you bolt a new one in. If the engine dropped a bearing, the pan, suction tube, cooler and filter head all hold debris. A new pump feeding dirty oil through a plugged cooler will read low pressure again and you will be back under the truck. Flush the system and cut the old filter open.
Install with a new pump gasket, torque the mounting bolts evenly, and check gear backlash against the drive gear before you close things up. Prime the pump before the first crank. After startup, verify oil pressure hot at idle and at rated speed with a mechanical gauge — not the dash reading — and confirm it holds after the engine reaches operating temperature.
3803698 Cross-Reference & Interchange Numbers
These manufacturer and aftermarket numbers commonly cross-reference to 3803698. Use them to identify the part — then confirm the exact fit by VIN or the number stamped on your old unit before you order. An interchange is a starting point, not a fitment guarantee.

Frequently asked questions
Will 3803698 fit my N14 if I only know it's a Celect Plus?
Not confirmed on engine family alone. The N14 went through several pump revisions, so the badge on the valve cover is not enough. Pull the number off your existing pump or run your engine serial number to verify. Cross-reference gets you close; the old part number closes it out.
My oil pressure is low at hot idle. Is it always the pump?
Often it is not. Worn main and rod bearings, a stuck pressure regulator, a plugged oil cooler, or a collapsed suction tube gasket all drop hot idle pressure. Check bearing clearances and the regulator before condemning the pump. If the pump gears show scuffing or excessive body clearance, replace it.
Is PAI 141294 the same pump as the Cummins numbers?
It is the aftermarket catalog number covering the same N14 Celect Plus lube pump assembly that the Cummins numbers reference. Different supplier, same application. All numbers are listed for identification purposes only and do not imply any affiliation with or endorsement by the original manufacturer.
