GR1803BR Motor Grader Air Filter 803190294 / 800101436 / AF25276
This engine air-filter element is listed for the GR1803BR motor grader with references 803190294, 800101436 and AF25276. The additional “277” shown in the earlier title is not treated here as a confirmed part number because its meaning is unclear. Before ordering, compare the complete markings, overall dimensions and both sealing ends with the installed filter.
Maintenance focus: A correct element must seal inside the housing. Even suitable-looking media cannot protect the engine if the end seal, gasket or housing contact does not match.
Dust protection depends on the seal
Motor graders often work close to fine dust. The air-cleaner housing, restriction indicator, clamps and intake pipe all contribute to engine protection. When servicing the element, inspect the clean side of the housing for dust tracks. A visible track can indicate a sealing, housing or installation problem that should be corrected before the machine returns to work.

Inspection during routine service
Clean the outside of the air-cleaner housing before opening it.
Remove the used element carefully so loose dust does not fall into the clean-air passage.
Inspect the housing, cover, clamps and intake hose for damage or gaps.
Compare the new element with the removed one before installation.
Check that the element seats evenly and the cover closes without forcing it.
Follow the machine maintenance schedule and the filter manufacturer’s handling instructions.
Why cross-reference numbers still need verification
803190294, 800101436 and AF25276 are grouped in the product record, but catalog numbering alone cannot show the condition of the housing or confirm every production configuration. If the old filter label is readable, send a direct photo. When it is unreadable, provide measured dimensions, end-view photographs and the GR1803BR serial plate.
Replacement decisions in dusty work
Do not judge filter condition only by surface colour. Service decisions should follow the restriction indicator and maintenance guidance for the machine. Avoid unapproved cleaning methods that can damage media or seals. If dust is found downstream of the element, inspect the complete intake path rather than simply installing another filter.

FAQ
Are 803190294, 800101436 and AF25276 confirmed cross-references?
They are grouped in this product record. Confirm them against the old element, dimensions and sealing construction before supply.
What does “277” mean in the earlier title?
The available record does not define it, so it is not presented as a confirmed part number.
Can the element be selected by outer diameter alone?
No. Length, inside diameter, end caps, gasket position and housing fit are also important.
What should I send for matching?
Send photos of all markings and both ends, measured dimensions, the air-cleaner housing label if available, and the GR1803BR serial plate.
Fitment note: Confirm the cross-reference and physical filter construction before installation.
