I put 2 of the same orders in due to a web page error and shortly after I was contacted by Deb from customer service asking if I meant to place both orders. She was very helpful, the email was very well written and it genuinely made me feel better about the whole experience. She resolved the issue quickly and with there not being much of customer service these days I was very happy so see that is not the case everywhere!!!

Frequently Asked Questions
What is the 4F6486 cylinder liner used for?
The 4F6486 cylinder liner forms the bore the piston rides in, providing a hard, true wearing surface and helping transfer combustion heat. A sound liner is central to engine sealing and life.
How do I install the 4F6486 cylinder liner?
Fitting the 4F6486 correctly comes down to clean surfaces and following the manual’s sequence. Work through these steps:
- Shut down, cool, and follow engine service procedures
- Remove the old liner and clean the block bore
- Inspect the bore, counterbore, and seal areas
- Fit the 4F6486 with new seals and the correct protrusion
- Verify protrusion and seating before completing assembly
Which Caterpillar machines is the 4F6486 compatible with?
The 4F6486 cylinder liner is used across many Caterpillar applications, but the correct fit depends on your exact model and assembly. Always cross-check fitment using your service manual or part reference guide before ordering. If you are still unsure, reach out to Propel Parts, our team will be happy to help you verify if this part fits your equipment.
Does the 4F6486 cylinder liner meet performance standards?
Yes. The 4F6486 is built to meet OEM specifications for fit, strength, and service life. When replacing, choose genuine or high-quality aftermarket parts that meet or exceed OEM specifications to keep the assembly protected.
How often should the 4F6486 be replaced?
Service life for the 4F6486 depends on operating conditions and load. Replace it on inspection findings or at the interval your manual specifies rather than waiting for a failure. This part is commonly replaced alongside the 7K9210 Seal Link, so it is worth checking both while the assembly is open.
What are the signs of a worn or failing 4F6486 cylinder liner?
When the 4F6486 reaches the end of its service life, the symptoms tend to show up first as performance or wear issues. Look for:
- Coolant or oil leaks around the liner
- Loss of compression or blow-by
- Scoring or excessive bore wear
- Cavitation pitting on the liner wall
Why is the 4F6486 cylinder liner important, and what related part is commonly replaced with it?
Replacing the 4F6486 when needed keeps the system within its designed clearances and loads, which extends the life of the surrounding parts and supports dependable performance. The 0931512 Ring Backup is commonly serviced together with this part, so it is worth replacing both while access is available.
