Excellent customer service and parts.
You guys have always gave excellent customer service!!! Very prompt responsiveness. Warranty services are superb. I have been using them for quite awhile now on equipment I have. Always great prices for parts! Keep up the great work guy's
Great pricing and fast shipping!
I'll admit that I was skeptical of propel parts, but they are an honest site and came through with the order. I was skeptical because I've never ordered heavy machinery parts, and didn't know who to trust. The parts that I ordered showed in stock, but after checking with their vendor, they only had half of the order in stock. I was notified the day after the order, and most of the parts arrived in a few days. There was one part that was not shipped putz but I was able to talk with who I assumed is the owner who rectified the situation and had the part overnighted to me.
I will say that communication speed could use a little work, but they will eventually get back with you.
Above and Beyond
Staff took care of issue that was nit created by them. Package was lost by UPS. Propel sent me another part Next Day Air to correct it.
Great Customer Service!
Had some difficulties with the website. Contacted customer service. Once I communicated the issues I was having Steven worked through getting my order processed and making sure I got my receipt and all issues resolved. Perfect!
Great customer service

Thank you!!
Great service at an affordable price to get my machine back going.
Product Questions
Frequently Asked Questions
What is the 8T6430 bolt used for?
The 8T6430 is a fastening bolt that secures parts on Caterpillar equipment, providing the clamp load that keeps a joint tight in service.
How do I install the 8T6430 bolt?
To install the 8T6430 properly, prepare the area first and confirm the result afterward. Use these steps:
- Shut the machine down and isolate power before service
- Clean the threads and mating faces so debris doesn't affect clamp load
- Inspect the threaded bore and the 8T6430 for damage
- Start the bolt by hand to avoid cross-threading
- Torque it to the value and sequence listed in your service manual
- Re-check torque after the first operating cycle if the manual advises
Which Caterpillar machines is the 8T6430 compatible with?
Fitment for the 8T6430 depends on your specific Caterpillar model and the assembly it serves, so confirm the application before you order. Check your manual or reach out to Propel Parts for help verifying fitment.
Does the 8T6430 bolt meet performance standards?
Yes. The 8T6430 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 8T6430 be replaced?
Plan to replace the 8T6430 during a rebuild of the surrounding components, or sooner if inspection shows it is past its serviceable limit.
What are the signs of a worn or failing 8T6430 bolt?
A worn 8T6430 usually gives early warning through the assembly it supports. Watch for these signs:
- Loss of torque or a slowly loosening joint
- Stripped, galled, or corroded threads
- Visible stretching or a necked-down shank
- Movement, fretting, or leaks at the joint
Why is the 8T6430 important, and what related parts work with it?
A sound 8T6430 is inexpensive insurance against larger repairs. Servicing it on time with parts that meet OEM specifications keeps the whole assembly working as intended. Related hardware on our site includes 6K9316 Nut and 5D6644 Shim.
