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!! -
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. -
Very helpful. Every question or request I had was answered quickly. I didn't have a parts book for my excavator but that was no problem for them. If you need parts for your Cat, give them a shot.

Customer service was great! There was a small problem with the part and they responded quickly and respectfully until was resolved! Highly recommended
-
Great service at an affordable price to get my machine back going.
Frequently Asked Questions
What is the 5S6051 gasket used for?
The 5S6051 is a gasket that fills the gap between two surfaces to create a tight seal. It keeps fluids and combustion gases where they belong.
How do I install the 5S6051 gasket?
A reliable installation of the 5S6051 starts with inspection and ends with verification. Follow this process:
- Shut down, cool, and depressurize the assembly before opening it
- Remove the old gasket and scrape the surfaces fully clean
- Inspect both faces for warping, pitting, or scoring
- Position the new 5S6051 so all ports and bolt holes line up
- Torque the fasteners in the correct sequence and re-check for leaks
Which Caterpillar machines is the 5S6051 compatible with?
Fitment for the 5S6051 depends on your specific Caterpillar model and the assembly it serves, so confirm the application before you order. If you are unsure don’t hesitate to reach out to Propel Parts for help verifying fitment.
Does the 5S6051 gasket meet performance standards?
Yes. The 5S6051 is manufactured to meet OEM specifications for tolerance and material quality. When replacing, choose genuine or high-quality aftermarket parts that meet or exceed OEM specifications for dependable, long-term performance.
How often should the 5S6051 be replaced?
Plan to replace the 5S6051 during a rebuild of the surrounding components, or sooner if inspection shows it is past its serviceable limit. The 8H9155 Seal Oil 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 5S6051 gasket?
Catching a failing 5S6051 early prevents wider damage. The common warning signs include:
- External leaks at the mating joint
- Loss of pressure or compression
- Coolant, oil, or gas cross-contamination
- A crushed, blown, or hardened gasket on inspection
Why is the 5S6051 gasket important, and what related part is commonly replaced with it?
Keeping the 5S6051 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 0336039 Seal O-Ring is another component from the same assembly that is commonly replaced at the same time.
