Shaun (Arizona, USA)100%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 6F6673 seal used for?
The 6F6673 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 6F6673 seal?
Fitting the 6F6673 correctly comes down to clean surfaces and following the manual sequence. Work through 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 6F6673 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 6F6673 compatible with?
Compatibility for the 6F6673 seal 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 6F6673 seal meet performance standards?
Yes. The 6F6673 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 6F6673 be replaced?
The 6F6673 is typically renewed during scheduled service or a related repair. In demanding, high-hour operation, inspect it more often to stay ahead of wear.
What are the signs of a worn or failing 6F6673 seal?
When the 6F6673 reaches the end of its service life, the symptoms tend to show up first as performance or wear issues. Look for:
- 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 6F6673 important, and what related parts work with it?
Replacing the 6F6673 when needed keeps the system within its designed clearances and loads, which extends the life of the surrounding parts and supports dependable performance.
