A quick guide to component location and specific applications across heavy machinery:
Piston: Located inside the Cylinder Liner, converts combustion force. ISUZU 4BZ2 Piston 8941746491.
Cylinder Head: Sits on top of the Engine Block, seals the combustion chamber. CUMMINS L10 Cylinder Head Assembly.
Flywheel Housing: Attached to the Rear of the Engine Block, mounts the transmission. KOMATSU PC450 Flywheel Housing.
Connecting Rod Bearing: Sits in the Connecting Rod Big End, reduces friction with crankshaft. CATERPILLAR 3408 Connecting Rod Bearing.
Oil Cooler: Integrated into the Engine Block/Filter Base, reduces engine oil temperature. KUBOTA V2203 Oil Cooler.
Diesel Pump: Mounted on the Engine Block Side, supplies high-pressure fuel. YANMAR 4TNV98 Diesel Pump.
Rocker Arm: Part of the Cylinder Head Valve Train, actuates the valves. WEICHAI WP13 Rocker Arm.
Piston Pin: Secures the Piston to the Connecting Rod. CUMMINS QSB4.5 Piston Pin.
Water Pump: Mounted on the Engine Front, circulates coolant. CATERPILLAR C15 Water Pump.
Thrust Washer: On the Crankshaft Main Bearing, limits crankshaft end play. KOMATSU S6D107E Thrust Washer Set.
Engine Malfunction: Excessive Oil Consumption (Part 9):
Equipment Model: CATERPILLAR 320D Excavator with 3066 Engine
Fault: Engine is consuming oil quickly, visible as blue smoke, and requires frequent top-ups.
Diagnosis & Solution: High oil consumption usually stems from oil leaking past the Piston Rings or worn Valve Stem Seals. In a heavy-duty 3066, the primary suspect is wear on the cylinder components. The solution involves measuring the clearance of the Piston in the Cylinder Liner. If clearance is excessive, a major engine repair is required, involving a complete Overhaul Kit. Replacing the worn Piston Ring Set (5-12121-004-0 equivalent) and corresponding Cylinder Liners (which can be Custom Engineered by us) will restore the necessary seal and bring oil consumption back to normal parameters, ensuring the engine runs with Precision Engineered performance.
