FAQ
Q: Is this piston a direct fit for my Cat 312D excavator? A: This part is designed for the Cat C4.4 engine, which powers the Cat 312D series. It is a direct replacement for OEM numbers 5081900 and 3636881. However, we recommend checking your engine’s serial number against our compatibility list or consulting your service manual to ensure a perfect match, as engine variations may exist.
Q: What is the recommended 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 with clean engine oil, and using a ring compressor to fit the assembly. Always follow the manufacturer’s torque specifications for connecting rod bolts and ensure proper ring gap alignment as per the Cat C4.4 service manual.
Q: Does this piston come with rings and a pin? A: This listing is for the piston assembly only (part number T426417). Piston rings and the wrist pin are typically sold separately. Please check with our sales team if you require a full piston kit that includes these components for a complete overhaul.
