3. Excavator Undercarriage Parts
The undercarriage supports machine weight and enables crawler excavators to move across difficult terrain.
Undercarriage components are exposed to abrasion, mud, rocks, impacts and continuous mechanical stress.
Common replacement parts include:
- Track chains
- Track shoes

- Carrier rollers
- Front idlers
- Sprockets

- Travel reduction gearboxes
- Swing gearboxes
- Swing bearings

- Internal gearbox components
For gearbox and final drive repairs, exact part identification helps avoid ordering incompatible components.
Customers should provide original manufacturer part numbers and relevant assembly identification details.
5. Excavator Cooling System Parts
Excavators operate in environments where dust, heavy loads and high ambient temperatures can increase cooling system demands.
Common cooling system components include:
- Engine radiators
- Hydraulic oil coolers
- Charge air coolers
- Cooling fans
- Fan drives
- Water pumps
- Thermostats
- Expansion tanks
- Hoses and connections
SORS® aftermarket cooling components may be considered where a suitable alternative is available for the original application.

Frequently requested parts include:
- Electronic control modules
- Joysticks and control switches
- Pressure sensors
- Speed sensors
- Temperature sensors
- Wiring components
- Relays and switches
- Operator control components

Electronic components may require precise configuration or programming compatibility. The original part number and machine identification should therefore be checked carefully before ordering.
Genuine, OEM or Aftermarket Excavator Parts: What Is the Difference?
Selecting the correct type of spare part depends on the customer’s technical requirements, budget and preferred sourcing option.
Genuine Excavator Parts
Genuine parts are supplied under the equipment manufacturer’s brand or through its authorized supply channels.
They are generally selected when the customer specifically requires original-branded components.
OEM Excavator Parts
OEM components are associated with original equipment manufacturing or supply.
Because the term OEM can be used differently across the industry, the component manufacturer and part specification should be clarified before purchase.
SORS® Aftermarket Excavator Parts
SORS® is the aftermarket spare parts brand of STOPARTS LTD.
It provides an alternative sourcing option for selected heavy equipment components.
Where available, SORS® replacement parts are intended for the corresponding specified equipment applications and should be selected using verified part-number references.
The right option depends on the machine, component, required specification and customer preference.
STOPARTS LTD can review available alternatives based on the requested part number.
How to Identify the Correct Excavator Spare Parts
One of the most common challenges when purchasing construction equipment parts is identifying the correct component.
Similar excavator models may use different assemblies depending on their serial number, engine configuration and production year.
To reduce ordering errors, buyers should prepare the following information:
- Equipment manufacturer – such as Caterpillar, Komatsu, Volvo or Hitachi.
- Machine model – the exact excavator model.
- Original part number – preferably taken from the manufacturer’s parts documentation.
- Required quantity – the number of units needed.
- Preferred part type – Genuine only, OEM or aftermarket alternatives accepted.
For engine assemblies, hydraulic pumps and certain other components, nameplate information may also be required to verify the correct configuration.
If you have a large list of spare parts, an Excel file containing original part numbers and quantities is the preferred format.
