Customer Reviews
Great people! Good and fast service. Always looking to help get what you need! 10/10 ????????
Propel parts is a good Cat vendor that provides a top notch service to customers from ordering to delivery. Their after sales service is really impressive.
Great customer service answered email question quickly.
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.
Australian buyer, sales where professional and very responsive with secure parts identification.
Highly recommend.

Product Questions
Frequently Asked Questions
What is the Caterpillar Washer 9X8257?
The 9X8257 is a hardened steel washer used in Caterpillar equipment assemblies. Washers distribute the load of a fastener across a broader surface area, prevent bolt loosening from vibration, and protect softer mating surfaces from damage.
What applications use the 9X8257 washer?
This washer is used across a wide range of Caterpillar equipment assemblies, from engine mounts and structural hardware to undercarriage and implement attachments. Consult your machine's parts manual for specific applications. Please reach out to Propel Parts for help verifying fitment if needed.
What grade or material is the 9X8257 washer?
The 9X8257 is a hardened steel washer manufactured to meet or exceed OEM specifications for surface hardness, thickness tolerance, and load-bearing capacity under heavy equipment operational stresses.
When should I replace a washer?
Replace the washer if it is:
- Bent, cupped, or deformed from over-torquing
- Showing signs of corrosion or surface pitting
- Fractured or cracked
- Missing from an assembly during repair
Using a compromised washer can lead to bolt loosening or joint failure over time.
Can I use a standard hardware store washer as a substitute?
It is not recommended. Heavy equipment fasteners require washers with specific hardness, dimensions, and surface finish to match the bolt grade and application load. Using an undersized or soft substitute can lead to fastener loosening or joint damage. Always use a part that meets OEM specifications.
Is the 9X8257 available as a high-quality aftermarket part?
Yes. The 9X8257 from Propel Parts is a premium aftermarket washer that meets or exceeds OEM specifications. It's built to the same dimensional and hardness standards as the original Caterpillar part.
