Great. !
Customer Service.
I recently had to cancel an order with Propel Parts, and I was thoroughly impressed by the prompt and efficient service I received. Steven handled my request with professionalism and speed, ensuring a hassle-free process. I've purchased parts from Propel Parts before and have never been disappointed. Their consistent reliability and excellent customer service keep me coming back.
BEST for Heavy Equipment Parts.
Awesome quality products! Better customer service! Steven is always a pleasure to work with and very prompt in assisting me - thank you!
Been buying from them for years and have almost never had an issue. The few times I had a question or something to handle, they have shown amazing customer service. Great product and a great company.
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.

Very good service.
Excellent company.
Great company to deal with. Answered my questions with detail and shipped me the part in good time! I will be dealing with them more in the future!
I put 2 of the same orders in due to a web page error and shortly after I was contacted by Deb from customer service asking if I meant to place both orders. She was very helpful, the email was very well written and it genuinely made me feel better about the whole experience. She resolved the issue quickly and with there not being much of customer service these days I was very happy so see that is not the case everywhere!!!
They are great !
Steven & Propel Parts were a huge help! We were able to place a large order and get it shipped out same day to avoid a line down situation for a customer due to a lost component. The order was even submitted after the 3pm cutoff for same day shipments and we got it the next morning!
Product Questions
Frequently Asked Questions
What makes the 9M1974 a "hard" washer and when is it required?
The designation "hard" refers to a heat-treated washer with a significantly higher hardness rating than a standard flat washer. Hard washers are required in high-load bolted joints where standard washers would deform or embed into the mating surface, causing joint preload loss and potential fastener loosening.
What standard size and material does this washer meet?
The 9M1974 meets Caterpillar's OEM specifications for hardness, dimensions, and surface finish required for its intended application. Always reference the product listing for exact dimensional data and confirm it matches the requirements stated in your service manual.
Can I substitute a standard flat washer for the 9M1974 hardened washer?
No. Substituting a standard washer for a hardened one in an application that specifies the latter is not recommended. The softer standard washer will deform under load, reducing clamping force and potentially leading to joint failure. Always use the specified washer type.
What models is the 9M1974 compatible with?
This hardened washer is used across various Caterpillar equipment assemblies. Confirm compatibility by referencing your machine's parts manual. Please reach out to Propel Parts for help verifying fitment if you are unsure which washer applies to your joint.
Should hardened washers be replaced every time a joint is serviced?
Hardened washers that show no signs of deformation, cracking, or corrosion can typically be reused. However, if the washer has embedded into a softer mating surface or shows any surface damage, replacement is required to restore the correct load-bearing profile of the joint.
Is there a catalog of compatible CAT hardware at Propel Parts?
Yes. Propel Parts maintains an extensive inventory of Caterpillar-compatible hardware components. Browse our hardware parts for heavy equipment to find the full range of washers, bolts, nuts, and fasteners available for your maintenance needs.
What warranty covers the 9M1974 hardened washer?
All hardware components from Propel Parts carry a 1-year warranty against material and manufacturing defects. Same-day weekday shipping and a 30-day return policy are standard.
