FAQ

Q1: Is this piston a direct fit for my Caterpillar 3116 engine?
A: Yes, this piston is designed as a direct replacement for the Caterpillar 3116 engine. It matches the OEM specifications (69mm diameter, correct pin height, and bowl geometry) for part numbers 107-7545 and 238-2716. We recommend verifying your engine serial number and existing piston part number before installation to ensure compatibility.

Q2: Does the piston come with the wrist pin and rings?
A: This product is a piston assembly that includes the piston pin (wrist pin). It does not typically include piston rings, which are often sold separately. We advise ordering new piston rings for a complete engine overhaul to ensure a proper seal and compression.

Q3: What is the installation procedure for this piston?
A: Installation should be performed by a qualified diesel mechanic. Standard procedures include cleaning the cylinder bore, lubricating the piston and rings, using a ring compressor, and torquing the connecting rod bolts to factory specifications. Always refer to the official Caterpillar service manual for your specific engine model for detailed torque values and procedures. Failure to follow correct procedures can result in engine damage.
