Motor Grader Hydraulic Filter – Element and Housing Identification
A hydraulic filter protects precision valves, pumps and actuators from contamination. The correct motor grader filter must match the circuit position, housing or element interface, seal and the filtration specification stated by the machine manufacturer.
What identifies the filter?
| Area | Evidence |
|---|
| Circuit position | Suction, pressure, return, pilot or breather location |
| Element | Complete code, outside/inside diameter, length and end-cap design |
| Housing | Port thread, flow direction, bowl or head style and mounting |
| Protection | Specified filtration rating, bypass arrangement and collapse/pressure requirement |
| Seal | O-ring size, cross-section, material requirement and seating location |
Why dimensions alone are insufficient
Two elements can fit the same cavity but use different media, bypass design or pressure capability. Do not invent or substitute a micron rating. Confirm the manufacturer specification from the original code and machine manual.
Contamination-control scenario
Clean the housing exterior before opening it. Inspect the removed element and oil for water, metal or abnormal debris. Protect the clean side from dirt, fit the correct seal and follow the filling or bleeding procedure. Investigate a restriction indicator rather than simply resetting it.

FAQ
Can an element be selected only by size?
No. Media, bypass, pressure capability and seal design also matter.
What micron rating does this filter have?
This page does not claim an unverified rating; confirm the original element code and service specification.
Should the housing be cleaned?
Follow the maintenance procedure while protecting the clean side from contamination.
Compatibility note: Confirm circuit position and the complete filter code before ordering.
