FAQ

Q: How can I confirm this piston fits my Volvo D13 engine?
A: Please verify your engine’s serial number and the existing piston part number. While this assembly corresponds to OEM numbers 21170742 and VOE21170742 commonly used in D13 engines, we recommend cross-referencing your specific unit. If you have the old piston, measure the outer diameter (should be 131.00 mm) and the top land diameter to ensure a match.

Q: Does this piston assembly come with rings and a pin?
A: This part is sold as a piston assembly, which typically includes the piston body and the piston pin. However, the piston rings are often sold separately. Please check your specific order or contact our sales team to confirm if rings are included in your purchase or if you need to order them separately to complete the rebuild kit.

Q: What is the recommended installation procedure for this piston?
A: Installation should be performed by a qualified diesel mechanic. Key steps include ensuring the cylinder bore is clean and within specification, lubricating the piston and rings with clean engine oil, and using a proper ring compressor to install the piston into the cylinder. Always follow the manufacturer’s service manual for your specific engine model for correct ring gap orientation and torque specifications for the connecting rod bolts.
