For engine power, we offer Injectors (Nozzles) such as the 387-9433 for the CAT C9/330/336 and the 387-9427 for the CAT 325 C7, alongside the Water Pump (354-4754 for CAT C6.6 ). Our focus on diesel engine parts and electrical control modules ensures we have the necessary heavy machinery repair parts to service your fleet of CAT off-highway trucks and wheel loaders as well.

Nomenclature Breakdown - Wiring Harness: A wiring harness is a bundle of electrical wires and cables that transmit power and data signals. It is located in the engine compartment or chassis of an excavator to connect various electrical components. Example: Caterpillar 345D Engine Wiring Harness. (Russian: Жгут проводов двигателя для Caterpillar 345D)

Nomenclature Breakdown - Injector (Fuel Nozzle): An injector is a valve that sprays fuel into the engine cylinders at high pressure. It is located in the engine cylinder head of a diesel engine . Example: Caterpillar 330 C9 Injector. (Russian: Форсунка для Caterpillar 330 C9)

Undercarriage and Mechanical Replacement Parts

The performance of construction machinery hinges on robust mechanical systems. We provide a full range of undercarriage parts including Track Chains (Chains) , Rollers (Track Rollers) , Idlers , and Sprockets , suitable for models like CAT 320, 325, 330, 345, and 336. Essential rotating components like the Slewing Ring (Swing Bearing) for the CAT 320D/323D (227-6081) are readily available. We also stock Starting Motors (Starters) , for example, the 348-7651 for the CAT 345 C13, and various Cooling System Components such as the Radiator Core for the CAT 320C (204-0996).

The Growshine product line also includes a wide selection of pins and bushings for boom and bucket linkages, such as the 234-3803 Boom/Stick Pin for the CAT 325D/329D. These wear and tear components are critical for reducing downtime in demanding environments.

Nomenclature Breakdown - Slewing Ring: A slewing ring is a large-diameter bearing that allows the upper structure of an excavator to rotate relative to the undercarriage. It is located between the chassis and the upper body of the excavator . Example: Caterpillar 374D Slewing Ring. (Russian: Опорно-поворотное устройство для Caterpillar 374D)

Nomenclature Breakdown - Starting Motor (Starter): A starting motor is an electrical motor that rotates the engine to initiate the combustion process. It is mounted on the engine flywheel housing of a heavy truck or construction engine . Example: Caterpillar C6.4 320D Starting Motor. (Russian: Стартер для Caterpillar C6.4 320D)

Nomenclature Breakdown - Hydraulic Cylinder Assembly: A hydraulic cylinder assembly is a linear hydraulic actuator that converts hydraulic energy into mechanical force. It is used in the boom, stick, and bucket linkages of an excavator . Example: Caterpillar 336 Hydraulic Cylinder Assembly. (Russian: Сборка гидроцилиндра для Caterpillar 336)

Example of Equipment Fault and Solution: A common issue with the CAT 320D Excavator is overheating of the hydraulic system due to a clogged Return Filter (Single Check Valve 173-4672) or main relief valve issue. Solution: First, check the hydraulic oil level and condition. If the oil is fine, inspect and replace the Single Check Valve (173-4672) in the return line to the main valve. If the issue persists, the main relief valve (204-2678) may need adjustment or replacement to ensure proper pressure relief, preventing heat build-up.

Nomenclature Breakdown - Atmospheric Pressure Sensor: An atmospheric pressure sensor is a device that measures ambient air pressure . It is installed on the engine intake manifold or ECU box of a heavy-duty diesel engine . Example: Caterpillar 330 Atmospheric Pressure Sensor. (Russian: Датчик атмосферного давления для Caterpillar 330)

Nomenclature Breakdown - Water Pump: A water pump is a mechanical device that circulates coolant between the engine and the radiator. It is mounted on the engine block of a truck or industrial engine . Example: Caterpillar C6.6 Water Pump. (Russian: Водяной насос для Caterpillar C6.6)

Nomenclature Breakdown - Pin Assembly (Pin): A pin assembly is a cylindrical steel component used to connect major linkages. It is located at the connection points of the boom, stick, and bucket of an excavator . Example: Caterpillar 390D Boom/Stick Pin Assembly. (Russian: Палец стрелы/рукояти для Caterpillar 390D)
