Glossary of Engineering Machinery Parts
Crankshaft with Gear: A rotating shaft in an engine which translates reciprocating linear motion of the pistons into rotary motion. It often has an attached gear for timing or power transmission. Example: Komatsu PC200-7 Crankshaft with Gear, 小松PC200-7曲轴带齿轮, Коленчатый вал с шестерней Komatsu PC200-7.
Bucket Cylinder Seal Kit: A set of seals designed to prevent hydraulic fluid leakage in the bucket cylinder of an excavator. Example: Komatsu PC75 Bucket Cylinder Seal Kit, 小松PC75铲斗油缸密封包, Комплект уплотнений гидроцилиндра ковша Komatsu PC75.
Camshaft Bearing: A bearing that supports the camshaft, which controls the opening and closing of the engine's valves. Example: Komatsu D65EX-12 Camshaft Bearing, 小松D65EX-12凸轮轴承, Подшипник распределительного вала Komatsu D65EX-12.
Piston Kit With Rings: A set including a piston and its corresponding piston rings, used to create a seal within the engine cylinder and transmit force from combustion. Example: Yanmar 3TNV88 Piston Kit With Rings, 洋马3TNV88活塞环组件, Поршневой комплект с кольцами Yanmar 3TNV88.
Main Bearing: The bearings that support the crankshaft within the engine block, allowing it to rotate smoothly. Example: Komatsu S6D125 Main Bearing, 小松S6D125主轴瓦, Коренной подшипник Komatsu S6D125.
Liner Seal Set: A set of seals used to prevent coolant and combustion gases from leaking around the cylinder liner in an engine. Example: Komatsu PC200-8 Liner Seal Set, 小松PC200-8缸套密封组件, Комплект уплотнений гильзы цилиндра Komatsu PC200-8.
Gasket Ex Manifold: A seal placed between the exhaust manifold and the cylinder head to prevent exhaust gas leaks. Example: Komatsu WA380-3 Gasket Ex Manifold, 小松WA380-3排气歧管垫片, Прокладка выпускного коллектора Komatsu WA380-3.
Piston Ring Set: A set of metallic rings that fit into the grooves of a piston to seal the combustion chamber, prevent oil from entering the chamber, and transfer heat from the piston to the cylinder wall. Example: Komatsu 4D95 Piston Ring Set, 小松4D95活塞环组件, Комплект поршневых колец Komatsu 4D95.
Bucket Link Pin: A pin that connects the bucket to the linkage system of an excavator, allowing for movement and digging. Example: Komatsu PC300LC-8 Bucket Link Pin, 小松PC300LC-8铲斗连杆销, Палец соединения ковша Komatsu PC300LC-8.
Rod Bolt: A bolt that fastens the connecting rod to the crankshaft in an engine. Example: Komatsu S6D102 Rod Bolt, 小松S6D102连杆螺栓, Болт шатуна Komatsu S6D102.
Tips for Sourcing Engineering Machinery Parts
Tip 1: Always provide the full part number when inquiring about a specific component. This ensures accuracy and speeds up the sourcing process.
Tip 2: Consider both OEM (Original Equipment Manufacturer) and high-quality aftermarket parts based on your budget and the specific application. Growshine International offers both options.
Tip 3: When searching online, use specific keywords including the brand, model, and part name to find the exact component you need.
Troubleshooting Common Issue: Hydraulic Cylinder Leakage
Problem: A Komatsu PC75 excavator is experiencing leakage from the bucket cylinder.
Possible Causes:
Damaged or worn cylinder seals (rod seal, piston seal, wiper seal).
Scratches or damage to the cylinder rod or barrel.
Loose or damaged hydraulic fittings.
Excessive pressure in the hydraulic system.
Troubleshooting Steps:
Visually inspect the cylinder for any external damage or leaks.
Check the hydraulic fluid level and for any signs of contamination.
Inspect the cylinder rod for scratches or dents.
Tighten any loose hydraulic fittings.
If the leakage persists, the cylinder seals likely need replacement. Refer to the Komatsu PC75 service manual for proper disassembly and reassembly procedures. Consider using a new Bucket Cylinder Seal Kit for Komatsu PC75 from Growshine International for a reliable repair.
If the cylinder rod or barrel is damaged, it may need to be repaired or replaced.
Check the hydraulic system pressure to ensure it is within the specified range.
