Ensure optimal engine performance and longevity with our high-quality "engine belt tensioner", specifically designed for "Komatsu PC200-8" excavators equipped with "6D107, QSB4.5, and QSB6.7" engines. This crucial component maintains the correct tension on the engine belts, preventing slippage and ensuring the efficient operation of critical systems like the alternator, fan, and water pump.

Product Specifications & Part Numbers:

We offer reliable "belt tensioners" compatible with the following part numbers:

6743-61-4120
6754-61-4111
3976834

These "engine parts" are engineered to meet or exceed OEM specifications, providing a perfect fit and reliable performance for your "Komatsu" machinery.

Key Features and Benefits:

Precise Tensioning: Maintains correct belt tension under varying loads and conditions, extending belt life and preventing component damage.
Durable Construction: Built with high-strength materials to withstand the harsh operating environments of heavy machinery.
Optimal Performance: Ensures efficient power transmission to essential engine accessories.
Direct Replacement: Designed for easy installation as a direct replacement for the original "Komatsu belt tensioner".
Compatibility: Perfectly suited for "Komatsu PC200-8" excavators utilizing "6D107, QSB4.5, and QSB6.7" engines.

Applications and Compatible Models:

The "engine belt tensioner" is a vital component in the belt drive system of diesel engines. Our tensioners are specifically compatible with:

Komatsu PC200-8 Excavators
Engines: Komatsu 6D107, Cummins QSB4.5, Cummins QSB6.7

The "Komatsu PC200-8" is a widely used hydraulic excavator in various heavy-duty applications, including:

Construction Sites: Excavating foundations, trenching, material handling.
Mining Operations: Loading and unloading materials, site preparation.
Road Building: Earthmoving, grading, and demolition tasks.
Quarrying: Breaking and moving rock and aggregate.

A reliable "belt tensioner" is critical in these demanding environments to maintain consistent engine accessory function and prevent unexpected downtime.

Frequently Asked Questions & Maintenance Tips:

Q1: How do I know if my belt tensioner needs replacing?

Troubleshooting: Look for signs like belt squealing, rattling noises from the tensioner pulley, visible vibration or jumping of the tensioner arm, or uneven wear on the belt. A visual inspection for cracks or excessive play in the pulley bearing is also recommended.

Maintenance Tip: Inspect the belt and tensioner regularly during routine engine checks, typically every few hundred operating hours or as recommended in your equipment's service manual.

Q2: Can a failing belt tensioner cause other engine problems?

Troubleshooting: Yes, absolutely. Incorrect tension can lead to belt slippage, reducing the efficiency of accessories like the alternator (causing charging issues), water pump (leading to overheating), and fan (affecting cooling). In severe cases, the belt can break, causing complete shutdown of these critical systems and potential engine damage.

Maintenance Tip: Replace the belt tensioner and the serpentine belt together as a preventative measure, especially during major engine overhauls or when replacing one of the components due to wear.

Q3: Is installation difficult?

Maintenance Tip: While the process varies by machine and engine model ("Komatsu PC200-8", "6D107", "QSB4.5", "QSB6.7"), replacing a belt tensioner typically requires basic mechanical knowledge and appropriate tools to release tension, remove the old unit, and install the new one. Always refer to the specific service manual for your "Komatsu" equipment or "Cummins" engine. If uncomfortable, professional installation is recommended.

Diesel Engine Parts Terminology:

Here are some common diesel engine components:

Fuel Injector / 喷油器 / Форсунка (Located in the cylinder head, sprays fuel into the combustion chamber) - e.g., "Caterpillar CAT 320D Fuel Injector"
Cylinder Head / 气缸盖 / Головка блока цилиндров (Covers the cylinders, contains valves and fuel injectors) - e.g., "Komatsu PC200-7 Cylinder Head"
Piston Ring / 活塞环 / Поршневое кольцо (Seals the gap between the piston and the cylinder wall, located on the piston) - e.g., "Cummins QSB6.7 Piston Ring"
Connecting Rod / 连杆 / Шатун (Connects the piston to the crankshaft) - e.g., " excavators Komatsu PC300-8 Connecting Rod"
Crankshaft / 曲轴 / Коленвал (Located at the bottom of the engine block, converts linear piston motion to rotational motion) - e.g., " bulldozers Caterpillar D8T Crankshaft"
Camshaft / 凸轮轴 / Распредвал (Located in the engine block or head, operates the engine valves) - e.g., " loaders Volvo L120H Camshaft"
Oil Pump / 机油泵 / Масляный насос (Circulates lubricating oil throughout the engine) - e.g., " trucks Freightliner Cascadia Oil Pump"
Water Pump / 水泵 / Водяной насос (Circulates coolant through the cooling system) - e.g., " generators Cummins 6CTA8.3 Water Pump"
Radiator / 散热器 / Радиатор (Located in front of the engine, dissipates heat from the coolant) - e.g., " excavators John Deere 350G Radiator"
Flywheel / 飞轮 / Маховик (Attached to the crankshaft, smooths engine rotation and connects to the transmission) - e.g., " graders CAT 140H Flywheel"

For all your "Komatsu PC200-8 parts", "6D107 parts", "QSB4.5 parts", "QSB6.7 parts", and other "diesel engine spare parts" needs, trust "Guangzhou Pinxin Engine Co., Ltd.". We provide quality parts to keep your heavy equipment operational.
