Product Details
Product Overview
This heavy-duty piston kit, identified by part number 65.02501-0222 (also referenced as 65.02501-0222B and 130602-01010), is a critical engine component designed for the Doosan Daewoo DE12 and D2366 series diesel engines. These engines are widely used in demanding off-highway equipment, including excavators, wheel loaders, and generator sets. The kit includes the piston, piston rings, and piston pin, providing a complete replacement solution for engine overhaul or repair.
Specifically engineered for heavy-duty applications such as the Doosan Solar 420LC-V, DH420, and DH500-7 excavators, this piston kit ensures reliable performance, durability, and precise fitment. It is a direct replacement for the original OEM components, offering a cost-effective alternative without compromising on quality or engine efficiency.
Note: While this piston kit is commonly used for the listed engine and machine models, we recommend verifying fitment by cross-referencing your original part number with the specifications provided below to ensure 100% compatibility.
Key Features & Benefits
Precision Engineering: Manufactured to stringent OEM specifications, ensuring exact dimensional accuracy and a perfect seal within the cylinder bore.
High-Strength Materials: Constructed from high-strength aluminum alloy (for the piston body) and forged alloy (for critical components), providing exceptional resistance to thermal stress, wear, and mechanical fatigue.
Complete Kit: Includes the piston, piston rings, and piston pin, simplifying procurement and ensuring all matched components are replaced simultaneously for optimal engine performance.
Enhanced Durability: Designed to withstand the extreme pressures and temperatures of turbocharged and intercooled diesel engines (DE12T, DE12TI), extending engine service life.
Fuel Efficiency: Advanced ring pack design helps reduce blow-by and oil consumption, contributing to better fuel economy and lower emissions.
Rigorous Quality Control: Each piston kit undergoes strict inspection procedures, and a Machinery Test Report is available upon request, providing confidence in the product’s reliability.
Global Compatibility: A direct replacement for multiple OEM part numbers, making it a versatile stock item for workshops servicing Daewoo/Doosan heavy equipment.

FAQ
Q1: How can I confirm this piston kit (65.02501-0222) fits my engine?
First, locate the engine model plate on your equipment. It should clearly state the engine model (e.g., DE12T or D2366). Then, remove the old piston and check the part number stamped on its crown. If it matches 65.02501-0222 or 65.02501-0222B, this kit is the correct replacement. If you are unsure, please contact our support team with your engine serial number and original part number for verification.
Q2: What is included in the piston kit? Do I need to buy rings and pins separately?
This is a complete piston kit. It includes one piston, a set of piston rings (typically compression rings and oil control rings), and a piston pin with retaining clips. You do not need to purchase these items separately. However, we recommend replacing the cylinder liners and bearings at the same time for a complete engine rebuild.
Q3: What is the recommended installation procedure for this piston?
Installation should be performed by a qualified diesel mechanic. Key steps include: 1) Clean the cylinder bore thoroughly. 2) Lubricate the piston, rings, and cylinder wall with clean engine oil. 3) Use a proper piston ring compressor to install the piston into the bore, ensuring the ring gaps are staggered. 4) Torque the connecting rod bolts to the manufacturer’s specified settings. Failure to follow correct procedures can lead to piston seizure or engine damage.
