A Delay Handled the Right Way
Honestly, if I were in Miami like my shipment was, I wouldn?t have been in a hurry to ship out either. I was frustrated at first ? delays cost me time on the job ? but Propel Parts stepped up.
Deb, Daniel and the team owned the mistake, kept the communication clear, and graciously refunded my shipping costs without making it a hassle. That kind of accountability is rare these days, and I genuinely appreciated how they handled it.
Things don?t always go perfectly, but these folks proved they?re more interested in doing right by their customers than just pushing parts out the door. Solid company, solid people.

P.S. Incredible quality on the pin as well. I had to do some custom modifying, and let?s just say the case hardening was ? well ? hard. Great Stuff! Thank you. -
Fast response and very attentive! Thanks Deb.

Frequently Asked Questions
What is the 5J0964 seal used for?
The 5J0964 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 5J0964 seal?
To install the 5J0964 properly, prepare the area first and confirm the result afterward. Use 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 5J0964 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 5J0964 compatible with?
The 5J0964 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 5J0964 seal meet performance standards?
Yes. The 5J0964 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 5J0964 be replaced?
Service life for the 5J0964 depends on operating conditions and load. Replace it on inspection findings or at the interval your manual specifies rather than waiting for a failure. When servicing this area, the 2054832 Seal O-Ring is commonly replaced at the same time.
What are the signs of a worn or failing 5J0964 seal?
A worn 5J0964 usually gives early warning through the assembly it supports. Watch for these signs:
- 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 5J0964 seal important, and what related part is commonly replaced with it?
A sound 5J0964 is inexpensive insurance against larger repairs. Servicing it on time with parts that meet OEM specifications keeps the whole assembly working as intended. During an overhaul, the 2S8960 Gasket is frequently replaced alongside this part.
