I’ve been ordering parts from propel for about 3 years & counting. I live in Hawaii where we have a hard time getting parts especially for decent prices with fast shipping. I've been 100% satisfied with the company and the customer service and will continue to use them. I recommend propel to everyone here in Hawaii and we are all happy to have you guys. Thank you!!!

Product Questions
Frequently Asked Questions
What is the 1039260 seal used for?
The 1039260 seal keeps fluids contained and contaminants out where two surfaces meet or a shaft rotates. A sound seal maintains pressure, prevents leaks, and protects the components it isolates.
How do I install the 1039260 seal?
A reliable installation of the 1039260 starts with inspection and ends with verification. Follow this process:
- Shut down and depressurize the system, then let it cool if needed
- Remove the old seal and clean the bore and shaft surfaces
- Inspect the sealing surface for scoring, pitting, or wear
- Lightly lubricate the 1039260 as directed and fit it square to the bore
- Seat it to the correct depth without distorting the lip, then check for leaks
Which Caterpillar machines is the 1039260 compatible with?
The 1039260 seal 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. Please reach out to Propel Parts for help verifying fitment.
Does the 1039260 seal meet performance standards?
Yes. The 1039260 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 1039260 be replaced?
Service life for the 1039260 depends on operating conditions and load. Replace it on inspection findings or at the interval your manual specifies rather than waiting for a failure.
What are the signs of a worn or failing 1039260 seal?
Catching a failing 1039260 early prevents wider damage. The common warning signs include:
- Visible fluid leaks or seepage at the joint
- Loss of system pressure
- Contamination found inside the assembly
- A hardened, cracked, or torn sealing surface
Why is the 1039260 important, and what related parts work with it?
Keeping the 1039260 in good condition protects the components around it and supports smooth, reliable operation. Maintaining the assembly with parts that meet OEM specifications helps you avoid unplanned downtime. Related hardware on our site includes 8M5010 Seal O-Ring and 6F9163 Gasket.
