Technical Definitions and Advanced Search Keywords

To support your procurement and Engine Maintenance, here are key component definitions and their applications on equipment from cummins, komatsu, and Caterpillar:

Camshaft: Located in the Engine Block or Cylinder Head, it controls valve timing. Example: Cummins B3.3 Camshaft.
Water Pump: Mounted on the Engine Block front, it circulates coolant. Example: Komatsu PC300-8 Water Pump.
Oil Filter: Attached to the Engine Block or Oil Cooler, it cleans the oil. Example: Caterpillar C15 Oil Filter Base.
Fuel Injector: Sits in the Cylinder Head, spraying fuel into the cylinder. Example: Isuzu 4HK1 Fuel Injector.
Glow Plug: Installed in the Cylinder Head for cold-weather starting (diesel). Example: Kubota V2403 Glow Plug.
Thermostat: Located in the Cooling System Housing, controls coolant flow. Example: Yanmar 4TNV98 Thermostat.
Cylinder Head: Bolts to the top of the Cylinder Block, sealing the combustion chamber. Example: Weichai WP12 Cylinder Head.
Connecting Rod Bearing: Fitted inside the Connecting Rod to protect the crankpin. Example: Cummins ISX15 Connecting Rod Bearing.
Thrust Washer: Installed at the Crankshaft to prevent excessive axial movement. Example: Komatsu 6D125 Thrust Washer.
Oil Pump: Located in the Oil Sump/Crankcase, circulates lubricating oil. Example: Caterpillar D5K Oil Pump.

Our Business Commitment and Technical Support

Honour Time Machinery Limited is dedicated to providing comprehensive Engine Assembly and Engine Component solutions worldwide. We ensure that our quality components, compatible with Cummins, Caterpillar, and Komatsu, meet the rigorous demands of heavy equipment operation.

Example Engine Diagnostic and Repair Solution:

Equipment: Komatsu PC200-7 Excavator with a SAA6D102E-2 Engine.
Fault: Low Oil Pressure at Operating Temperature and High RPM.
Treatment Plan: While the Oil Pump is the primary suspect, a deeper issue can be worn Crankshaft Bearings (Main or Connecting Rods), allowing oil to escape too quickly. The solution involves dropping the oil pan to inspect bearing clearances. Replacing worn Main Bearings and the Oil Pump with high-quality components is essential to restore proper oil pressure and protect the entire engine from catastrophic failure.
