Baldwin BT8391 Hydraulic Filter

The Baldwin BT8391 is a spin-on hydraulic filter designed for Ford and New Holland tractors. It uses a 74 micron rating to capture contaminants in hydraulic systems. The unit includes a G401 integral gasket for a secure seal during installation. This replacement part suits owners maintaining agricultural equipment.

Upgrade from worn filter elements

A used filter that has reached its service interval should be replaced with this unit to restore proper hydraulic flow. The jump is worth it when pressure drops or contamination indicators signal reduced efficiency. Continued use of a clogged element risks damage to pumps and valves. This filter restores the intended filtration performance for the application.

Verify thread size and dimensions

Before ordering, confirm the equipment requires a 1 1/8 In. -16 thread size for proper fitment. Check that the 3 11/16 in outside diameter and 5 21/32 in height match the housing clearance. Ensure the hydraulic system operates within the 74 micron rating specification. This product is not for buyers who need a different micron rating or thread configuration.

Questions about this item

What thread size does the BT8391 hydraulic filter need to mount on the tractor?

The filter uses a 1 1/8 In. -16 thread, so the tractor's filter head must match that exact size for a proper seal.

How do I install the spin-on BT8391 and what step is often missed?

Lubricate the included G401 integral gasket with clean hydraulic oil, spin the filter on until the gasket contacts the base, then tighten an additional three-quarters to one full turn.

When should the BT8391 hydraulic filter be replaced?

Replace the filter at the tractor manufacturer's recommended service interval or whenever the hydraulic system's condition monitor indicates the 74-micron element is saturated.
