Turbocharger (Cummins QSB6.7): Installed on the engine exhaust manifold to increase air intake. Used in PC210-8 excavators.
Water Pump (Komatsu 6D102): Mounted on the front of the engine block to circulate coolant. Essential for PC200-6 cooling systems.
Fuel Injector (Caterpillar C7): Located in the cylinder head to spray fuel into the combustion chamber for E325D models.
Piston (Isuzu 4HK1): Reciprocates inside the cylinder liner of ZX200-3 excavators to convert combustion into motion.
Gasket Head (Kubota V2203): Seals the joint between the cylinder head and block in U35 mini-excavators.
Crankshaft (Yanmar 4TNV98): The main rotating shaft of the engine, found in Vio75 excavators.
Oil Pump (Weichai WD615): Located in the oil pan or front cover to provide lubrication for heavy-duty trucks and loaders.
Starter Motor (Komatsu 4D95): Engages the flywheel to start the engine on PC120-5 models.
Alternator (Caterpillar 3116): Generates electricity to charge batteries on IT28G integrated tool carriers.
Main Valve (Isuzu 6BG1): Controls hydraulic flow on EX200-5 excavators, often working alongside the throttle motor.
Case Study: Engine Speed Instability on Komatsu PC200-7
Problem: The engine speed fluctuates and does not respond to dial changes.
Solution: Inspect the Komatsu Float Switch 7861-92-4800 and the Throttle Motor. Often, carbon buildup on the throttle linkage or a faulty motor sensor is the cause. Replacing with our high-quality 2523-9014 motor or 7861-92-4800 switch restores smooth operation immediately.
Maintenance Tip: Regularly check your Gasket Head and Liner Kit for leaks. Using high-purity coolant and 15W-40 oil significantly extends the life of your Engine Bearings and Turbocharger.
