Product Details

Product Overview

This high-quality piston assembly, featuring the critical part number 1073565 / 107-3565, is specifically engineered for the Caterpillar 3306 and 3306C diesel engines. As a core component of the engine’s power cylinder group, this piston is designed to withstand the extreme pressures and temperatures found in heavy-duty machinery.

Manufactured to meet OEM specifications, this 1073565 piston provides a direct replacement for worn or damaged units. It is a vital part for maintaining compression, reducing blow-by, and ensuring optimal combustion efficiency in Caterpillar equipment used across various industries, including construction, mining, and material handling. The assembly includes the piston body and a precision-machined wrist pin for a secure and reliable connection to the connecting rod.

Key Features & Benefits

• OEM Standard Fitment: Manufactured to match the exact dimensions, weight, and material specifications of the original Caterpillar part, ensuring a direct bolt-in replacement without modifications.
• Superior Durability: Constructed from high-strength aluminum alloy with advanced heat treatment to resist thermal fatigue, cracking, and deformation under high-stress operating conditions.
• Precision Pin Fit: The included wrist pin is case-hardened and precisely ground to minimize clearance, reducing noise and extending the life of the piston and connecting rod bushings.
• Enhanced Oil Control: Features precisely machined ring grooves and oil return holes to optimize oil control, reduce consumption, and minimize carbon buildup in the combustion chamber.
• Reduced Downtime: As a critical wear item, replacing the piston with this high-quality 1073565 unit during an overhaul ensures reliable engine performance and significantly reduces the risk of unexpected breakdowns in the field.
• Rigorous Quality Control: Each piston undergoes strict inspection for dimensional accuracy, material hardness, and surface finish before shipment.

FAQ

Q1: How can I confirm this 1073565 piston will fit my Caterpillar 3306 engine?

To ensure a perfect fit, please check the part number stamped on your existing piston. The primary numbers for this unit are 1073565 or 107-3565. Additionally, verify your engine’s serial number and the cylinder liner bore size (standard or oversize). This piston is designed for the standard OEM bore diameter of the 3306 engine.

Q2: Does this kit include piston rings? What other parts do I need for a rebuild?

This product is strictly the piston assembly and wrist pin. It does not include piston rings, cylinder liners, or bearings. For a complete engine overhaul, we recommend purchasing a full overhaul gasket kit and a set of piston rings (e.g., part number 7N-5806 or equivalent) separately to ensure all wear items are replaced simultaneously.

Q3: What is the recommended installation procedure for this piston?

Professional installation is highly recommended. Key steps include: 1) Thoroughly clean the cylinder bore. 2) Lubricate the piston pin and connecting rod bushing with clean engine oil. 3) Use a proper ring compressor to install the piston into the liner. 4) Ensure the arrow on the piston crown is oriented correctly according to the engine’s rotation direction. 5) Always replace the connecting rod bolts and nuts with new ones and torque them to the manufacturer’s specifications.
