Key Part Definitions:
1. Front Crankshaft Seal (曲前油封 - Qū qián yóufēng - Передний сальник коленчатого вала): A seal located at the front end of the crankshaft, preventing oil leakage. Example: Komatsu PC200-5 uses the front crankshaft seal with part number AE3297G.
2. Rear Crankshaft Seal (曲后油封 - Qū hòu yóufēng - Задний сальник коленчатого вала): A seal located at the rear end of the crankshaft, typically where the flywheel is attached, preventing oil leakage. Example: Caterpillar CAT320C uses the rear crankshaft seal with part number AZ4291E.
3. Engine Block (发动机缸体 - Fādòngjī gāngtǐ - Блок двигателя): The main structural component of an engine, containing the cylinders. Example: Isuzu 4HK1 engine block is a crucial part of Hitachi ZX200-3.
4. Piston (活塞 - Huósāi - Поршень): A component that moves within the cylinder, driven by the combustion of fuel. Example: Yanmar 4TNV98L engine pistons are vital for the operation of Hyundai R150.
5. Connecting Rod (连杆 - Liánkǎn - Шатун): A rod that connects the piston to the crankshaft, converting reciprocating motion into rotary motion. Example: Mitsubishi 6D34 engine connecting rods are essential in Kobelco SK230-6.

Frequently Asked Questions (Common Knowledge):
1. What are the common causes of engine oil seal failure in construction machinery? Common causes include wear and tear due to age and usage, improper installation, high engine temperatures, and contamination of the oil.
2. How often should engine oil seals be replaced in heavy trucks? The replacement interval for engine oil seals in heavy trucks varies depending on the truck model, engine type, and operating conditions. It's generally recommended to inspect them regularly and replace them when signs of leakage or damage are observed, or as part of scheduled maintenance.
3. What are the benefits of using high-quality aftermarket parts for agricultural machinery?

Troubleshooting Tip: Hydraulic Cylinder Leakage in Excavators
Problem: A common issue in Komatsu PC200 series excavators is leakage from the hydraulic cylinders, particularly the boom cylinder. This can result in reduced lifting power and inefficient operation.
Possible Causes: The leakage is often due to damaged or worn-out hydraulic cylinder seals. Over time, these seals can degrade due to pressure, temperature fluctuations, and contamination in the hydraulic fluid.
Solution: The most effective solution is to replace the damaged seals in the hydraulic cylinder. This involves disassembling the cylinder, inspecting all seals and components for wear or damage, and replacing the faulty seals with new, high-quality seals. Ensure the hydraulic fluid is also checked for contamination and replaced if necessary. Properly reassembling the cylinder and testing it under pressure will ensure the leakage is resolved and the excavator's performance is restored.
