MANN-FILTER Hydraulic Filter - W1374/2

The primary function is to remove contaminants from the hydraulic fluid, protecting vital components like pumps and valves in automatic transmissions and hydraulic systems from wear and damage.

Replacement intervals vary depending on the equipment and operating conditions. Consult your equipment's service manual for the manufacturer's recommended replacement schedule, typically based on operating hours or mileage.

The filter has a height of 177 mm, an outer diameter of 135 mm, a thread size of G 1 1/4, and a gasket with an outer diameter of 111 mm and an inner diameter of 100 mm.

While it lists common OEM replacements, it's crucial to verify that the filter's dimensions, thread size, and specifications precisely match your equipment's requirements. Always refer to your equipment's service manual for definitive compatibility.

This filter is designed for standard automatic transmission fluids and general operating hydraulic fluids. Always use the type of fluid recommended by your equipment manufacturer.

Over time, the filter will become clogged with contaminants. A clogged filter can lead to restricted fluid flow, reduced system performance, increased wear on components due to dirty fluid, and potentially system failure.

Ensure the mounting surface is clean and free of debris. Verify the filter was tightened correctly (hand-tight plus 3/4 to 1 turn). Check that the gasket is properly seated and lubricated.

A clogged filter can restrict fluid flow. Check if the filter needs replacement. Also, ensure the hydraulic fluid level is correct and the fluid is not contaminated or degraded.

Use a proper oil filter wrench designed for spin-on filters. If stuck, apply a penetrating oil around the base (avoiding the mounting surface) and allow it to soak before trying again. Ensure you are turning it in the correct direction (usually counter-clockwise).
