Aftermarket Caterpillar Compact Equipment Parts
Construction Parts PNW supplies aftermarket wear and replacement parts for Caterpillar skid steers, compact track loaders, mini excavators, and selected compact construction equipment. Our focus includes rubber tracks, undercarriage components, bucket wear parts, cutting edges, attachment tools, and hardware.
Compact machines have many configuration and serial-number differences. Provide the complete model and serial number whenever possible, or return to the Caterpillar Parts Hub for other Cat equipment families.
Rubber Tracks and Compact Undercarriage
Compact track loaders and mini excavators may use rubber tracks, rollers, idlers, sprockets, track adjusters, recoil assemblies, and mounting hardware. Rubber-track fitment depends on width, pitch, link count, guide style, and machine configuration—not simply the model printed on the machine.
How to Read a Rubber Track Size
Track sizes are generally expressed as width × pitch × link count. Measure carefully and confirm the guide configuration. If the size marking is unreadable, send photos of the track, sprocket, and undercarriage along with the machine serial number.
Undercarriage Inspection
Check rollers, idlers, sprockets, tension, alignment, and accumulated debris before installing a new track. A worn or seized connected component can damage a replacement track.
Browse skid steer rubber tracks and rubber track resources for additional guidance.
Bucket Teeth, Cutting Edges, and Hardware
Compact-equipment wear parts can include bucket teeth, adapters, pins, retainers, bolt-on cutting edges, side cutters, wear plates, and plow bolts. Identify the bucket or attachment as well as the carrier machine. Tooth system, adapter dimensions, hole spacing, and cutting-edge measurements help confirm fitment.
See our Bucket Teeth guide and Ground Engaging Tools hub.
Attachment Wear Parts
Skid steers and compact loaders use buckets, trenchers, brooms, augers, breakers, grapples, mulchers, and other attachments. Replacement components may include cutting tools, teeth, blades, pins, bushings, hoses, coupler parts, and hardware. Always include the attachment manufacturer, model, and serial number.
How to Identify the Correct Compact Equipment Part
- Complete Cat model and serial number
- Track size or undercarriage measurements
- Attachment manufacturer and model
- Existing part or casting number
- Component dimensions and mounting pattern
- Clear photos of the part and surrounding assembly
- Application and operating conditions
Send these details through our Part Finder Request.
Common Compact Equipment Wear Indicators
- Cracked, cut, or de-tracking rubber tracks
- Hooked sprocket teeth or seized rollers
- Repeated track-tension loss
- Rounded or missing bucket teeth
- Thin or loose cutting edges
- Excessive attachment pin movement
Inspect the complete system and follow manufacturer service procedures before installing parts.
Caterpillar Compact Equipment Parts FAQs
Can a Cat model number identify the rubber-track size?
Not reliably by itself. Serial-number configuration, track width, pitch, link count, and guide style should be confirmed.
What information is needed for attachment parts?
Provide both the carrier machine details and the attachment manufacturer, model, serial number, part number, dimensions, and photos.
Should sprockets be inspected when replacing rubber tracks?
Yes. Worn sprockets, seized rollers, alignment problems, and incorrect tension can shorten replacement-track life.
