At the beginning, I experienced significant delays and communication issues regarding my order, which honestly caused serious concern because the parts were urgently needed for an important project.
However, after continuous follow-up, the Propel Parts team handled the matter professionally, provided shipment tracking, and the parts finally arrived successfully.
I especially appreciate their willingness to communicate, acknowledge the issue, and continue working toward resolving the situation.
In international business, delays can sometimes happen, but what matters is the final commitment to resolving the issue properly.
Thank you to Daniel and the team, and hopefully future transactions will be smoother for both sides. -
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. -
Quick and efficient.
Great products and a great team to deal with. We had a small issue with a missing part and the Customer Services Team dealt with it quickly and efficiently and in a way which left me, the customer, feeling entirely satisfied. Would highly recommend. -
Quick Respond.
The quick respond much appreciated.
Keep this up.
Frequently Asked Questions
What is the 2357679 seal used for?
The 2357679 is a sealing component that blocks fluid leakage and keeps dirt and debris out of the assembly. Reliable sealing is key to maintaining pressure and protecting internal parts.
How do I install the 2357679 seal?
To install the 2357679 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 2357679 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 2357679 compatible with?
Compatibility for the 2357679 seal varies by machine and configuration, so cross-check it for your Caterpillar equipment 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 2357679 seal meet performance standards?
Yes. The 2357679 is engineered to meet OEM specifications for material, dimensions, and durability. When replacing, choose genuine or high-quality aftermarket parts that meet or exceed OEM specifications so the part performs the way it was designed to.
How often should the 2357679 be replaced?
The 2357679 is typically renewed during scheduled service or a related repair. In demanding, high-hour operation, inspect it more often to stay ahead of wear. When servicing this area, the 5F3106 Seal O-Ring is commonly replaced at the same time.
What are the signs of a worn or failing 2357679 seal?
A worn 2357679 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 2357679 seal important, and what related part is commonly replaced with it?
A sound 2357679 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 1613411 Gasket Ctp is frequently replaced alongside this part.
