OEM Cross-Reference
This S6KT coupling is manufactured as a direct replacement for original Caterpillar engine components. While specific OEM part numbers may vary by equipment configuration, the S6KT model designation is the primary reference for compatibility. For precise cross-referencing, please verify your existing part number against the following compatible identifiers:
Engine Model: S6KT (Primary reference)
Alternative references: Consult your equipment’s parts manual using the S6KT engine model number
Note: This is not an exhaustive list. Always verify physical dimensions and bolt patterns with your existing coupling before installation.
Compatibility
This S6KT coupling is commonly used for Caterpillar diesel engines in the following applications:
Construction Equipment: Excavators, bulldozers, wheel loaders, and compactors
Industrial Machinery: Pumps, compressors, and conveyor drives
Agricultural Equipment: Tractors, harvesters, and irrigation pumps
Generator Sets: Standby and prime power generators
Marine Applications: Propulsion systems and auxiliary engines
Material Handling: Forklifts, cranes, and telehandlers
Fitment Note: This coupling is designed for the S6KT engine model. Always confirm engine serial number and coupling dimensions (bore diameter, length, and bolt pattern) with your existing part to ensure correct fitment.

FAQ
Q1: How can I confirm this S6KT coupling will fit my engine? A: Verify your engine model number is S6KT. Then measure your existing coupling’s overall length, bore diameter, and bolt circle pattern. Compare these dimensions with the OEM-size specifications of this product. If unsure, contact our support team with your engine serial number and existing coupling measurements for verification.
Q2: What should I check during installation? A: Ensure both shaft ends are clean and free of burrs. Align the coupling halves within recommended tolerances (typically 0.1-0.2 mm angular and parallel misalignment). Apply appropriate thread locker to fasteners and torque to manufacturer specifications. After installation, rotate the assembly by hand to confirm free movement before starting the engine.
Q3: How often should this coupling be inspected or replaced? A: Inspect the coupling annually or every 2,000 operating hours, whichever comes first. Look for signs of rubber deterioration, cracks, or excessive wear. Replace immediately if you notice abnormal vibration, unusual noise, or visible damage. In harsh environments (high temperature, chemical exposure), more frequent inspections are recommended.
