Frequently Asked Questions
What is the 8M4986 O-ring seal used for?
The 8M4986 is an O-ring style seal used to prevent leaks at a joint or connection. Correct sizing and material let it hold pressure without hardening or extruding.
How do I install the 8M4986 O-ring seal?
A reliable installation of the 8M4986 starts with inspection and ends with verification. Follow this process:
- Depressurize the system and shut the machine down before service
- Remove the old O-ring and clean the groove thoroughly
- Inspect the groove and mating face for nicks or debris
- Lubricate the 8M4986 as directed and seat it evenly in the groove
- Reassemble carefully so the O-ring isn't pinched, then check for leaks
Which Caterpillar machines is the 8M4986 compatible with?
Fitment for the 8M4986 depends on your specific Caterpillar model and the assembly it serves, so confirm the application before you order. Or reach out to Propel Parts for help verifying fitment.
Does the 8M4986 O-ring seal meet performance standards?
Yes. The 8M4986 is manufactured to meet OEM specifications for tolerance and material quality. When replacing, choose genuine or high-quality aftermarket parts that meet or exceed OEM specifications for dependable, long-term performance.
How often should the 8M4986 be replaced?
Plan to replace the 8M4986 during a rebuild of the surrounding components, or sooner if inspection shows it is past its serviceable limit.
What are the signs of a worn or failing 8M4986 O-ring seal?
Catching a failing 8M4986 early prevents wider damage. The common warning signs include:
- Leaks or weeping at the sealed connection
- A flattened, nicked, or hardened ring on removal
- Loss of pressure in the circuit
- Swelling or extrusion from the groove
Why is the 8M4986 important, and what related parts work with it?
