XCMG Air Filter Set 803172683 / 803172684
References 803172683 and 803172684 identify a paired inner-and-outer air-filter arrangement for XCMG excavator service enquiries. The two elements work together inside the engine air-cleaner housing: the primary element handles the normal dust load while the inner safety element provides an additional barrier during operation and service.
This listing covers the number pair, but the number printed on each removed element and the air-cleaner housing should still be checked. Different excavator configurations may use housings that look alike but require different elements.
Set Information
Part name: Inner and outer engine air-filter elements
Part numbers: 803172683 and 803172684
Application family: XCMG excavator engine air intake
Supply check: Compare both old elements and the housing label
Why the Pair Is Important
The air cleaner is part of the engine's protection system in dusty construction environments. A correct outer element must seal against the housing, and the inner element must fit without interfering with the primary element. Ordering the pair by part number helps avoid mixing elements from different housing families.
Inspection and Replacement Guidance
Inspect the housing, cover, clips and sealing surfaces when the filters are serviced. Dust on the clean side of the housing, a damaged seal or a distorted element requires investigation before the machine returns to work. Follow the XCMG or engine service manual for inspection and replacement intervals. Do not use impact, aggressive washing or uncontrolled compressed air that may damage the media.
Information Needed for Accurate Supply
Provide photos of both filter labels, the air-cleaner housing label and the machine data plate. State whether you need the complete pair or only one element. If only one number remains readable, include the dimensions and clear end-view photos as supporting information rather than relying on measurements alone.
Frequently Asked Questions
Should the inner and outer filters be replaced together?
Follow the machine service manual and inspect both elements. Supplying the matched pair is often helpful when service history is uncertain, but the required interval depends on the application.
Can the filters be selected by appearance?
No. Similar-looking elements can have different seals or internal construction. Use both part numbers and the housing information.
Which number belongs to the inner element?
Confirm the marking on each original element or its packaging. This page intentionally avoids assigning positions when the actual machine has not been inspected.
