Collection: Caterpillar (CAT) Parts

Browse parts listed for Caterpillar (CAT) equipment on PartsNonStop. Compare the part number, component description and supplier details before requesting a quotation. Each listing has its own stock reference, condition and availability.

Find the correct CAT part

Start with the manufacturer part number from your parts catalogue or the existing component. A machine model alone may not identify the correct replacement. Include your machine serial number and any relevant engine or component serial number when asking the supplier to confirm compatibility.

For example, view the CAT 242-1741 sensor assembly listing for its recorded machine references and enquiry details.

Compare condition and supply details

Read the condition shown on each product rather than assuming all parts are new. Ask for current photographs, confirmation of availability and details of any testing, rebuild work or warranty that the supplier offers. A catalogue listing does not guarantee suitability for every machine configuration.

Request a parts quotation

Include the part number, stock reference, quantity and delivery destination in your enquiry. Confirm the final price, lead time and shipping arrangements with the supplier before ordering.
