Product representation
The starter Komatsu 600-813-7122 is a key component of electrical equipment of the Komatsu heavy equipment, designed to reliably start the engines in the most severe operating conditions. He specializes in working with powerful diesel engines of brands SAA6D107E, SAA6D114E and SAA6D125E, which are equipped with excavators, loaders and road construction equipment of Komatsu. Due to its high power, strength and ideal compatibility, this starter becomes an integral element to maintain the effective operation of construction, mining and agricultural projects.
1. General purpose and role in the system of technology
The starter is responsible for the transfer of the engine from a static state to the working one: it rotates the crankshaft, providing sufficient air compression in the cylinders to launch combustion. For heavy Komatsu equipment, which often works under high loads and in extreme climatic conditions (from low temperatures to strong vibrations), the starter must have high reliability. The compact design of the starter 600-813-7122 allows it to be located in the limited space of the motor compartment, and the optimized connection diagram simplifies integration with the system of electrical equipment of the equipment. Due to this, even with a long stop of equipment in frosty conditions (-35 ° C and below), the starter guarantees a quick and stable launch without overloading the battery and reducing the risk of downtime at the facility.
2. Technical characteristics
The main technical parameters of the starter Komatsu 600-813-7122 are thought out for maximum adaptation to powerful Komatsu engines:
Power: 5.5 kW is enough power to start engines up to 12 liters, which meets the requirements of the PC200-8 and PC300-8 excavators and the WA380-6 loader.
Torque: 120 Nm - high torque ensures fast crankshaft rotation (up to 300 rpm) in 1-2 seconds, even when the oil in the engine freezes.
Voltage: 24V is the standard voltage for Komatsu heavy equipment electrical equipment, ensuring compatibility with the 6CT-8.5 battery model.
Overall dimensions: Length 280 mm, width 165 mm, height 140 mm, weight 12 kg. These parameters allow easy installation of the starter without modification of the engine compartment.
Operating temperature range: From -35°C to +80°C. This is achieved through the use of heat-resistant materials and sealed connections that protect internal components from overheating and freezing.
3. Design and materials
The 600-813-7122 starter is designed for maximum strength and durability. It consists of three main units: an electric motor, a gearbox, and a solenoid. Each element is made of high-quality materials:
Housing: Made of cast aluminum grade A356 with an anti-corrosion cathode coating 20 microns thick. This provides protection from moisture, sand and aggressive environments, and also reduces the overall weight of the starter.
Starter Pinion: Made of high-strength 20CrMnTi steel with heat treatment (carburizing and quenching), which improves its wear resistance and rigidity. The pinion size (11 teeth) is specially selected for the Komatsu engine gear wheel, preventing wear during starting.
Electric Motor: Equipped with a magnetic anchor made of 10JN80 steel and graphite brushes, which provide low resistance and a long service life (up to 8,000 starts). The rotor is made using copper with high electrical conductivity, which reduces heating during operation.
Solenoid: Made of permalloy (an alloy of iron and nickel) with a hermetically sealed seal, which guarantees its performance even in high humidity (up to 95%). The solenoid quickly locks the gear and supplies current to the motor.
4. Compatibility and scope of application
The 600-813-7122 starter is designed exclusively for Komatsu equipment, eliminating compatibility issues. The main models of equipment it works with are:
Excavators: PC200-8, PC220-8, PC300-8, PC360-8 - widely used in construction and mining.
Wheel loaders: WA380-6, WA470-6 - designed for loading and transporting goods.
Road rollers: GD655-5, GD675-5 - used in road construction and repair.
In these types of equipment, the starter demonstrates high reliability: for example, on the PC300-8 excavator, operating in coal mining conditions, it reliably starts the engine more than 50 times a day, even at a temperature of -25 ° C. In agriculture, on D65PX-17 tractors, the starter easily copes with starting the engine after a long stop in the cold time of day.
5. Rules of operation and maintenance
To maximize the service life of the starter 600-813-7122, it is important to follow simple rules:
Checking the contacts: Every 50 working hours, inspect the starter connection contacts - they should be clean and strong, without oxidation. If necessary, clean the contacts with gray sandpaper.
Battery Voltage Check: Battery voltage should be at least 22V. Low voltage increases the load on the starter and may cause overheating.
Brush replacement: Replace the graphite brushes with genuine Komatsu parts every 3,000 starts or every 2 years. Brush wear below 3 mm reduces the starter's efficiency.
Storage: For long-term storage (more than 6 months), the starter should be stored in a dry room at a temperature of +5°C to +25°C. Before installation, check for leaks and lubricate the gear with a special metal lubricant.
Repair: Repairs must be performed only at Komatsu authorized service centers using genuine parts. Unauthorized repairs may result in engine failure and void the warranty.
6. Conclusion
The starter Komatsu 600-813-7122 is a high-quality and reliable component that provides a stable launch of Komatsu heavy equipment in any conditions. Thanks to a powerful electric motor, strong design and ideal compatibility, it is the best choice for owners and operators of construction, mining and agricultural machinery. Compliance with the rules of operation and regular maintenance allow us to maximize the starter potential, reduce repair costs and extend the service life of all Komatsu equipment. To buy an original starter, it is recommended to contact the official Komatsu dealers - this guarantees receiving a certified product with a full guarantee for 2 years or 5,000 working hours.
