FAQ
Q: How can I confirm this piston will fit my Caterpillar C7.1 engine?
A: The most reliable method is to remove your old piston and measure its height (should be 145mm) and combustion chamber diameter (should be 76.5mm). Additionally, verify the part number stamped on the old piston matches one of our reference numbers: 5042903, 504-2903, or 369-3188.
Q: What other parts should I replace when installing a new piston?
A: For a complete and reliable engine overhaul, it is highly recommended to replace the piston rings, piston pin, circlips, and cylinder liner simultaneously. Always use new gaskets and seals for the cylinder head and oil pan. This ensures proper sealing and prevents premature wear.
Q: Do you provide any documentation for customs clearance or quality verification?
A: Yes. We can provide a commercial invoice, packing list, and bill of lading for customs. For quality verification, we can supply a machinery test report and a video of the outgoing inspection upon request. Please contact our sales team to arrange this before shipping.
