Baldwin B40056 Hydraulic Spin-On Filter

The Baldwin B40056 is a spin-on hydraulic filter designed for equipment maintenance. It fits hydraulic systems requiring a 7-micron rating and M27 x 2.0 mm threads. Maintenance crews use it to protect hydraulic circuits from particle contamination.

Thermals Noise and Power Draw

As a passive filtration component, the B40056 generates no heat, noise, or electrical draw. It operates solely through fluid pressure differential across the media. Normal use imposes no thermal or acoustic load on the host machine.

Replaces Worn Spin-On Cartridges

This filter replaces spent spin-on cartridges with matching thread, diameter, and micron specifications. The upgrade is justified when the service interval is reached or pressure differential indicates media saturation. It is not suited for systems needing finer micron ratings or different thread profiles.

Questions about this item

How do I install the B40056 spin-on hydraulic filter and what step is often missed?

Thread the filter onto the M27 x 2.0 mm port by hand until the gasket contacts the base, then tighten 3/4 to 1 full turn. The step often missed is lubricating the gasket with clean hydraulic fluid before installation.

What maintenance or replacement will the B40056 filter need later?

Replace the filter at the equipment manufacturer's recommended service interval or when the pressure differential indicator signals restriction. The 7 micron rating captures fine particles, so timely replacement prevents bypass and protects hydraulic components.

What limit appears first on the B40056 filter during sustained use?

The 7 micron media will load with contaminants first, increasing pressure drop across the element. Once the bypass valve opens, unfiltered fluid circulates, so monitor the service indicator and change the filter before that point.
