Everything fine, thank you. The only thing with which I had a problem in your Software, is that when I have more than 10 different items on the list, I can't scroll to the first ones. But besides that, I am very happy in going on with buying your parts.

Frequently Asked Questions
What is the 1552793 seal used for?
The 1552793 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 1552793 seal?
Fitting the 1552793 correctly comes down to clean surfaces and following the manual’s sequence. Work through these steps:
- 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 1552793 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 1552793 compatible with?
The 1552793 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. If you are unsure don’t hesitate to reach out to Propel Parts for help verifying fitment.
Does the 1552793 seal meet performance standards?
Yes. The 1552793 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 1552793 be replaced?
Service life for the 1552793 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 6L1648 Seal O-Ring, so it is worth checking both while the assembly is open.
What are the signs of a worn or failing 1552793 seal?
When the 1552793 reaches the end of its service life, the symptoms tend to show up first as performance or wear issues. Look for:
- 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 1552793 seal important, and what related part is commonly replaced with it?
Replacing the 1552793 when needed keeps the system within its designed clearances and loads, which extends the life of the surrounding parts and supports dependable performance. The 5L4940 Gasket is commonly serviced together with this part, so it is worth replacing both while access is available.
