Description
Fleetguard 3937557S is a genuine Cummins Filtration power-steering reservoir element that drops in for Nelson 87904F (and 87904M) and International 1698964C92 / 1698964C91. Rated 9 micron at beta=2 and 20 micron at beta=20, the cellulose element protects steering pumps and gearboxes from particulate that breaks down hose, seals, and pump rotors on Cummins-powered International medium-duty trucks and other equipment using the Nelson reservoir.

Applications
This power-steering filter fits Nelson reservoir housings used on:
- International / Navistar medium-duty trucks with Nelson power-steering reservoirs (1990s–2000s)
- Cummins-powered industrial and on-highway equipment plumbed with the Nelson 87904 reservoir
Confirm reservoir housing and filter dimensions before ordering. The 3937557S is an internal reservoir element — not a spin-on power-steering filter.
