The Double Order Catastrophe
My co-worker placed an order and wasn't sure it went through online. I later placed the same order thinking the previous order didn't go through. To my surprise both orders went through, and I needed to cancel one of the orders. I called and spoke with someone who instructed me someone would contact me about the situation. I was contacted by Misty and she said she would do her best to cancel one of the orders but not sure if she could because they were next day orders. A small tome later I received an email saying she was able to cancel one of the orders. Thank you to Misty and the entire Propel Parts Team. Greatly appreciated!! -

Frequently Asked Questions
What is the 1R6573 washer used for?
The 1R6573 is a washer that distributes load under a bolt or nut, guarding the mating surface and supporting consistent clamp force.
How do I install the 1R6573 washer?
A reliable installation of the 1R6573 starts with inspection and ends with verification. Follow this process:
- Power down the machine and isolate the assembly before service
- Clean the seating surface and check it for damage or burrs
- Place the 1R6573 in the correct orientation under the fastener
- Torque the fastener to specification so the washer seats evenly
Which Caterpillar machines is the 1R6573 compatible with?
Compatibility for the 1R6573 washer varies by machine and configuration, so cross-check it for your Caterpillar equipment before ordering. If you are unsure don’t hesitate to reach out to Propel Parts for help verifying fitment.
Does the 1R6573 washer meet performance standards?
Yes. The 1R6573 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 1R6573 be replaced?
The 1R6573 is typically renewed during scheduled service or a related repair. In demanding, high-hour operation, inspect it more often to stay ahead of wear. The 8S1723 Bolt Master Link is often renewed during the same service, so many technicians replace both at once to reduce downtime.
What are the signs of a worn or failing 1R6573 washer?
Catching a failing 1R6573 early prevents wider damage. The common warning signs include:
- A joint that won’t hold torque
- Cupping, cracking, or flattening of the washer
- Marking or embedding into the mating surface
- Corrosion that weakens the contact area
Why is the 1R6573 washer important, and what related part is commonly replaced with it?
Keeping the 1R6573 in good condition protects the components around it and supports smooth, reliable operation. Maintaining the assembly with parts that meet OEM specifications helps you avoid unplanned downtime. For a complete repair, the 8T4956 Hex Cap Screw is another component from the same assembly that is commonly replaced at the same time.
