Cat blade pins.
Easy transaction good web site.
Great pricing and fast shipping!
I'll admit that I was skeptical of propel parts, but they are an honest site and came through with the order. I was skeptical because I've never ordered heavy machinery parts, and didn't know who to trust. The parts that I ordered showed in stock, but after checking with their vendor, they only had half of the order in stock. I was notified the day after the order, and most of the parts arrived in a few days. There was one part that was not shipped putz but I was able to talk with who I assumed is the owner who rectified the situation and had the part overnighted to me.
I will say that communication speed could use a little work, but they will eventually get back with you.

This is my second time that I bought something from it, first time delivery time was in one week from US to Serbia
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!!!
Customer service was great! There was a small problem with the part and they responded quickly and respectfully until was resolved! Highly recommended
Product Questions
Frequently Asked Questions
What is the Caterpillar 2457339 front seal used for?
The Caterpillar Seal GP (Front) 2457339 is a front‑facing seal designed to prevent leaks in rotating or stationary components of heavy machinery. It creates a secure barrier that keeps lubricants and fluids contained within the system while protecting internal parts from dirt and contamination.
Which Caterpillar machines commonly use the 2457339 front seal?
To ensure the 2457339 is the correct fit for your machine, cross-reference the part number with your equipment manual or parts catalog. If you have any doubts, the Propel Parts team is available to point you in the right direction.
What does a front seal do in heavy‑duty machinery?
A front seal like the 2457339 maintains the integrity of fluid systems by preventing oil, hydraulic fluid, or coolant from escaping around shafts or housings. It helps maintain proper pressure and lubrication, which is essential for smooth engine or drivetrain performance.
Is the 2457339 front seal an OEM or aftermarket replacement part?
It\'s a premium aftermarket replacement. The 2457339 is designed to match OEM specifications in fit, form, and function. If you\'d like to confirm it\'s the right choice for your application, the Propel Parts team is available to help.
How do I install the 2457339 front seal correctly?
To install the 2457339 front seal properly:
- Clean the sealing surfaces thoroughly to remove any debris, old
> sealant, or fluid residue.
- Position the seal squarely in its housing or groove to avoid
> twisting.
- Carefully press the seal into place using the proper seal driver or
> installation tool. Reassemble surrounding components and tighten fasteners to the torque specifications recommended in your equipment's service manual. Proper installation helps ensure a leak‑resistant seal and long‑lasting performance.
What are the signs that a front seal like 2457339 needs replacement?
Common signs include:
- Fluid leaks around the front housing or shaft area
- Loss of oil or fluid pressure
- Contaminated fluid with debris or moisture
- Unusual noise or vibration due to inadequate lubrication
Replacing a worn seal early helps prevent more serious mechanical damage and costly downtime.
Why is using the correct front seal important for Caterpillar equipment?
The right 2457339 matters — an incorrect fit can introduce play, misalignment, or leakage that stresses other components and shortens equipment life. A correctly spec\'d replacement keeps the system working as designed.
