helpful and professional.
quick and professional service.
Excelente atencion y refacciones de calidad
Fast response and answers all my questions in a polite manner. Highly recommend.
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!!!
Customer service was excellent today! I have never had a company go behind the scenes to see what was happening with my payment error and resolve it so I could complete my order without having to do it all over again. Hats off to Propel Parts!

Product Questions
Frequently Asked Questions
What is the 8G4027 pin used for?
The 8G4027 pin locates and connects components, transferring load while allowing the designed movement between parts. A sound pin keeps the linkage tight and accurate.
How do I install the 8G4027 pin?
To install the 8G4027 properly, prepare the area first and confirm the result afterward. Use these steps:
- Shut the machine down and support the assembly before service
- Drive or press out the old pin and inspect the bores
- Clean and check the bores for wear or ovality
- Fit the 8G4027 with the correct orientation and retention
- Confirm the joint moves correctly and is properly secured
Which Caterpillar machines is the 8G4027 compatible with?
The 8G4027 pin is used across many Caterpillar applications, but the correct fit depends on your exact model and assembly. Always cross-check fitment using your service manual or part reference guide before ordering. Please reach out to Propel Parts for help verifying fitment.
Does the 8G4027 pin meet performance standards?
Yes. The 8G4027 is built to meet OEM specifications for fit, strength, and service life. When replacing, choose genuine or high-quality aftermarket parts that meet or exceed OEM specifications to keep the assembly protected.
How often should the 8G4027 be replaced?
Service life for the 8G4027 depends on operating conditions and load. Replace it on inspection findings or at the interval your manual specifies rather than waiting for a failure.
What are the signs of a worn or failing 8G4027 pin?
A worn 8G4027 usually gives early warning through the assembly it supports. Watch for these signs:
- Play, knocking, or rattling at the joint
- Visible wear, scoring, or galling on the pin
- Misalignment of the connected parts
- A loose or backed-out retainer
Why is the 8G4027 important, and what related parts work with it?
A sound 8G4027 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 6H6269 Ring Wear and 8J1620 Bearing.
