Construction Machinery Component Glossary
Understanding the function and placement of key engine and hydraulic components is essential for maintenance:
Piston Ring: Installed in the piston grooves. Cummins QSB6.7 Engine - Piston Ring. Seals the combustion chamber and transfers heat.
Hydraulic Piston Shoe: Attached to the swash plate in an axial piston pump. Komatsu PC200-6 Excavator - Piston Shoe. Transmits force to the pistons to pump fluid.
Cylinder Liner: A removable sleeve fitted into the engine block. Isuzu 6BG1 Engine - Cylinder Liner. Protects the cylinder block from wear.
Thrust Plate (Bearing): Located on the crankshaft main bearing journals. Caterpillar C7 Engine - Thrust Plate. Prevents excessive axial movement of the crankshaft.
Turbocharger: Bolted to the exhaust manifold. Weichai WP10 Engine - Turbocharger. Increases engine power by forcing compressed air into the combustion chamber.
Water Pump: Mounted on the engine block or timing cover. Kubota V3307 Engine - Water Pump. Circulates coolant through the engine and radiator.
Injector: Screws into the cylinder head. Yanmar 4TNV98 Engine - Diesel Injector. Atomizes and sprays fuel into the cylinder.
Connecting Rod: Connects the piston to the crankshaft. Cummins ISX15 Engine - Connecting Rod. Converts the linear motion of the piston into rotary motion.
Crankshaft: Sits in the bottom of the cylinder block. Komatsu SAA6D125E Engine - Crankshaft. The main rotating component of the engine.
Hydraulic Gear Pump: Often attached to the main pump or engine via a power take-off (PTO). Bobcat T300 Skid Steer - Pilot Gear Pump. Used to supply low-pressure pilot control fluid.
Troubleshooting Tip: Bobcat T300 Skid Steer Hydraulic System Failure
Fault: A Bobcat T300 Skid Steer experiences slow or weak lift/tilt functions, especially when the hydraulic oil is warm, indicating a loss of pressure.
Potential Solution: This often points to internal wear or failure within the main hydraulic pump or the 704-24-28201 main piston pump.
Diagnosis: Check the hydraulic oil level and filter first. If the problem persists, perform a pressure test. Low main pump pressure suggests a faulty pump or severely damaged components like the cylinder block or piston shoes (HPV118HW).
Repair Action: If the pump is confirmed bad, replace it with a genuine quality unit or use a reliable heavy equipment hydraulic pump parts online overhaul kit. Inspect for metal debris in the system and flush the entire hydraulic circuit to prevent secondary component failure.
