Bobcat mini excavators run a compact undercarriage loop — rubber tracks, rollers, idler, sprocket, and hardware — matched by model generation and serial number. The parts guide for Bobcat machines covers the track fitments, the steel parts, and the cross-references that keep a compact machine working. For an Ontario fleet running Bobcat excavators beside Bobcat loaders, the parts plan covers both machines from one record.

Bobcat Compact Excavator Range and Undercarriages
Bobcat's compact excavator range spans the mini class, and each model generation uses a matched undercarriage: rubber track loop, bottom rollers, carrier rollers, front idler, and drive sprocket. The range is compact, but the configurations differ by generation.
The parts map starts with the model and serial number. Bobcat machines of the same name can carry different undercarriages across years, and the serial number settles which one applies.
Rubber Track Fitments for Bobcat Models: Size and Pitch
Bobcat excavator tracks are matched by width, pitch, and link count, with the size code on the old track as the fastest confirmation. The track drives through the sprocket, so the pitch has to match the drive.
Confirm the track size against the model generation and the serial number before ordering. A Bobcat track that is right in width but wrong in pitch will skip on the drive.
The Bobcat compact range changes track sizes across generations, and the machine serial number is the field that picks the right page in the parts book. The size code on the old track confirms the pick, and the two together — serial number and size code — are the confirmation the supplier needs before dispatch.
The tread pattern is the second part of the Bobcat track choice: the compact machine's jobs — urban work, landscaping, and light excavation — each suit a different pattern, and the pattern affects grip and surface marking. Match the tread to the dominant job and confirm it with the size code, and the track arrives right for both the fit and the work.
Rollers and Idlers for Bobcat Excavators
Bobcat bottom rollers and carrier rollers are matched by diameter, flange style, and mounting, and the front idler sets the track line. The steel parts wear on the compact machine's duty: rental use, urban work, and abrasive sites each leave a different pattern.
Identify the steel parts by position and part number, and inspect for the compact-machine pattern: roller flats, weeping seals, and idler flange wear. Replace the worn positions with the track change where the readings align.
Common Part Numbers and Cross-References That Settle the Fit
Bobcat part numbers identify the component family and configuration, and the cross-reference maps the OEM number to the aftermarket part. Read the old part number, photograph it, and confirm the cross-reference against the serial number.
The cross-reference is the fastest route to a confirmed fit. Keep the mapped number with the machine record so the next order is a lookup.
Wear Patterns on Bobcat Undercarriages
Bobcat undercarriages wear by the compact-machine pattern: track lug and body wear on abrasive sites, roller flats under load, and idler flange loss over hours. Rental machines show the fastest wear because the duty changes with every renter.
Measure the track, rollers, and idler at every service and record the readings with the hours. The trend schedules the replacement, and it is the same discipline on a Bobcat as on any machine.
The rental pattern deserves a separate line in the plan: a rental machine that sits idle between jobs wears differently from one that works every day, and the inspection has to catch the wear the renters leave behind. Checking the undercarriage at every return keeps the rental machine ready for the next customer.
The compact-machine plan is also a parts-procurement plan: the track, rollers, and idler are ordered against the serial number with the fitment confirmed, and the hardware ships with the set. A Bobcat owner who orders the compact set as one package gets one delivery and one stop, which is the whole point of the undercarriage plan.
Keeping Bobcat Fleets Running in Canada: One Record Each
For a Bobcat fleet, the plan is one record per machine: serial number, part numbers, and wear readings on file, and the common parts ordered ahead of the cycle. The record keeps a mixed Bobcat fleet — excavators and loaders — running from one parts list.
Confirm the fitment and the delivery window before the order, and keep the confirmation with the record. A Bobcat fleet that plans the compact undercarriage like a budget line keeps its machines working.
| Bobcat fitment field | What it settles |
|---|---|
| Machine model, generation, and serial number | The undercarriage configuration |
| Old part number or size code, photographed | The component cross-reference |
| Component family and position | The right part for the position |
| Cross-reference against the serial number | The aftermarket match |
| Delivery window | The maintenance stop plan |
Questions to Ask Before You Order
- What track size and pitch does my Bobcat serial number use?
- Which roller, idler, and sprocket part numbers apply?
- Is the cross-reference confirmed in writing before dispatch?
Frequently Asked Questions
Do Bobcat mini excavators and Bobcat loaders share tracks?
Not necessarily. Excavator and loader track systems are matched to each machine type. Confirm the track by machine model and serial number.
How do I find the right Bobcat undercarriage part?
Use the old part number and the machine serial number together, and cross-reference both with the supplier. The cross-reference settles the aftermarket part.
Why do Bobcat rental machines wear their undercarriages fast?
The duty changes with every renter, and abrasive or urban work varies by job. Measure the wear at every service and order from the trend.
