Applicable Equipment

This piston (Part Number 6252-31-2110) is suitable for Komatsu excavators and other heavy machinery powered by the following diesel engine models:

Komatsu SAA6D125E-6 Engine
Komatsu 6D125 Engine (various sub-models like 6D125-1, S6D125, etc. using this piston part number)

These engines are commonly found in Komatsu excavator models such as (but not limited to):

PC400 series (e.g., PC400-7, PC450-7)
PC450 series
Other Komatsu heavy equipment utilizing these engine platforms.

*Always verify compatibility using your specific equipment model and engine serial number.*

Application Scenarios & Case Analysis

Komatsu excavators equipped with SAA6D125E-6 and 6D125 engines are workhorses in demanding environments. The reliable operation of the pistons is crucial for maintaining power and efficiency in these applications:

Construction Sites: Heavy-duty digging, trenching, and material handling for infrastructure projects, commercial buildings, and residential developments. A well-functioning piston ensures the engine delivers consistent power for deep excavation and heavy lifting.
Mining & Quarrying: Extracting and loading rock and overburden in challenging conditions. The piston's durability is tested by continuous high-load operation and exposure to dust and debris. Reliable pistons mean less downtime and higher productivity in material extraction.
Road Building: Preparing ground, moving large volumes of earth, and assisting in paving operations. Consistent engine performance, facilitated by quality pistons, is essential for maintaining project timelines and achieving desired earthmoving volumes.
Case Scenario Example: A Komatsu PC450 excavator working on a large-scale highway construction project requires reliable engine power for continuous excavation and loading of dump trucks. The SAA6D125E-6 engine with high-quality pistons ensures the necessary horsepower and torque are available throughout long shifts, preventing delays caused by engine performance issues. The piston's robust design helps it endure the constant load cycles and varying engine temperatures encountered during heavy earthmoving, contributing to the project's efficiency and profitability.

Common Installation Problems & Solutions

Proper installation is crucial for piston longevity and engine performance. Here are common issues and their solutions:

Problem: Incorrect Piston Ring Gap: If ring gaps are too tight, rings can butt and seize; if too wide, compression and oil control are compromised.
Solution: Always measure and adjust ring gaps according to the engine service manual specifications using a feeler gauge.
Problem: Improper Piston Orientation: Pistons often have a specific orientation mark (e.g., 'Front', dot, or notch) that must align correctly during installation. Installing backwards can cause interference or damage.
Solution: Identify and follow the orientation marks on the piston and connecting rod carefully, referencing the service manual.
Problem: Damage During Installation: Scratching the cylinder wall, piston skirt, or rings during insertion can lead to premature wear and failure.
Solution: Use a proper piston ring compressor and ensure the cylinder bore is clean and lubricated. Insert the piston and rod assembly smoothly and squarely.
Problem: Insufficient Lubrication: Failing to adequately lubricate the piston, rings, cylinder bore, and piston pin before installation can cause immediate scuffing or seizure upon start-up.
Solution: Generously apply clean engine oil to all contact surfaces of the piston, rings, pin, connecting rod bushing, and cylinder bore prior to assembly.
Problem: Incorrect Connecting Rod Bolt Torque: Over-tightening or under-tightening connecting rod bolts can cause bearing failure, rod distortion, or bolt fatigue.
Solution: Use a calibrated torque wrench and follow the precise torque specifications and sequence outlined in the engine service manual.

*Always consult the official Komatsu service manual for detailed, model-specific installation procedures and specifications.*
