Product Summary
This is a piston pin for Develon/Doosan DE08 series engines, used in excavator models such as DX260LCA, DX300LCA, DL250, SD300, and DL507. It connects the piston to the connecting rod, transferring combustion forces and ensuring stable piston movement. Part numbers 65.02502-0010, 65.02502-0206, and 65.02502-0106 are interchangeable. We supply this pin as original factory (made in Korea) or aftermarket (made in China). Single gross weight is 1.000 kg, packed in a cardboard box measuring 20 × 20 × 10 cm.

Product Function
The piston pin is a critical component that connects the piston to the connecting rod. Its main functions are:
- Power transmission – Transfers the high-temperature, high-pressure gas force from the piston to the connecting rod, driving the crankshaft.
- Load buffering – Absorbs shock and inertia forces during high-speed engine operation, reducing piston vibration and preventing seizure.
- Motion stabilization – Keeps the piston aligned within the cylinder, maintaining proper clearance and ensuring smooth engine operation.
Regular inspection of the piston pin and its bushings is essential during engine overhauls, as wear can lead to knocking, piston damage, or catastrophic engine failure.
