Frequently Asked Questions
What is the Caterpillar Seal 6L7814 / 6L5423 used for?
The 6L7814 (also cross-referenced as 6L5423) is a precision seal used in Caterpillar equipment to prevent fluid leakage at rotating shafts, static joints, or dynamic sealing points. Depending on the application, this may function as an oil seal, crankshaft seal, or other type of lip or face seal in engine or drivetrain assemblies.
Are part numbers 6L7814 and 6L5423 interchangeable?
Yes, in many cases these are cross-referenced part numbers for the same seal. Caterpillar occasionally updates part numbers during engineering revisions. It is always good practice to verify compatibility using the current part number listed in your machine's parts manual before ordering.
Is this a high-quality aftermarket seal?
Yes. The 6L7814/6L5423 seal from Propel Parts is a premium aftermarket replacement that meets or exceeds OEM specifications for dimensions, material properties, and sealing performance. It is a direct replacement for the original Caterpillar seal.
How do I know when the 6L7814 seal needs to be replaced?
Replace this seal when you observe oil leaks at the location where the seal is installed, visible damage to the seal lip such as cracking or hardening, or any time the shaft or housing is disassembled during a major service. Seals are inexpensive relative to labor costs ??? it is always wise to replace them during any disassembly.
Which Caterpillar equipment models use the 6L7814 seal?
This seal fits a range of Caterpillar machines. For confirmed compatibility with your specific model and serial number, please reach out to Propel Parts for help verifying fitment.
What is the correct way to install the 6L7814 seal to prevent leaks?
Clean the housing bore and shaft thoroughly before installation, use a seal driver of the correct diameter to press the seal in squarely, ensure it is flush with or slightly recessed below the bore face as specified, and lightly coat the seal lip with clean oil before the shaft is installed to prevent dry-start damage.
Where can I find more seal options for Caterpillar equipment?
