Customer Reviews
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!!!

Frequently Asked Questions
What is the 4T2479 pin used for?
The 4T2479 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 4T2479 pin?
Fitting the 4T2479 correctly comes down to clean surfaces and following the manual sequence. Work through 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 4T2479 with the correct orientation and retention
- Confirm the joint moves correctly and is properly secured
Which Caterpillar machines is the 4T2479 compatible with?
The 4T2479 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. Or reach out to Propel Parts for help verifying fitment.
Does the 4T2479 pin meet performance standards?
Yes. The 4T2479 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 4T2479 be replaced?
Service life for the 4T2479 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 4T2479 pin?
When the 4T2479 reaches the end of its service life, the symptoms tend to show up first as performance or wear issues. Look for:
- 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 4T2479 important, and what related parts work with it?
