❓ FAQ

FF42000 fits Cummins filter heads using 3903640, 3931065, 4990879, 4938729 or 3934763, and the same can is used on Atlas Copco compressors (57743916), Ingersoll-Rand 13887484, Komatsu 6732-71-6112, Volvo 243004 and 36845, and Renault Trucks 5000814227.

Yes. FF42000 replaces FF42001 and FF5494 and is the user-friendly version of FF5018, FF5033, FF5052 and FF5074. The thread is M16 x 1.5-6H INT, the overall height is 116.26 mm (4.577 in) and the gasket OD is 71.45 mm (2.813 in), so the can goes straight onto the existing stud.

FF42000 is rated 20 micron on the first pass and 10 micron on the second pass, with 96% efficiency. The two-stage media catches the fine debris that a single-stage element releases back into the fuel flow.

Lubricate the gasket, spin the can on by hand until the gasket contacts the head, then tighten to the torque printed on the housing or in the service manual. The 1/2 in socket recess in the base is there for removal, not for over-tightening on installation.

Cummins injection pumps and injectors run on clearances of a few microns, so abrasive dust or free water that gets past the filter wears plungers and nozzles. That is why FF42000 combines 96% efficiency with water separation and why the interval should not be stretched.

Description

Product Overview

FF42000 is a spin-on fuel filter with a crush-proof housing, 116.26 mm (4.577 in) overall height, 82.3 mm (3.24 in) seam diameter and a 71.45 mm (2.813 in) gasket, threading on with M16 x 1.5-6H INT. It replaces FF42001, FF5494 and is the user-friendly version of FF5018, FF5033, FF5052 and FF5074, crossing to Cummins 3903640, 3931065, 4990879, 4938729 and 3934763 as well as Baldwin BF7524, Donaldson FFP55-0440, Fram P-3711 and WIX 33124. Rated 20 micron first pass and 10 micron second pass at 96% efficiency, it removes dirt and separates water before the fuel reaches the injection pump.

Key Features

Crush-proof housing — the can is built to take handling and pressure spikes without denting, so an impact does not start a leak at the seam.
Ribbed body and 1/2 in socket — the ribs give a grip for hand fitting and the 1/2 in socket recess takes a bar for removal when the can is tight.
Anti-cross-thread design — the thread lead-in lets the can start square on the stud, which is what stops spills and damaged threads at service time.
Two-stage filtration — 20 micron on the first pass and 10 micron on the second pass hold fine debris that a single-stage element lets through.
96% efficiency with water separation — dirt and free water come out together, protecting pump plungers and injector nozzles from abrasive wear.
