Everything fine, thank you. The only thing with which I had a problem in your Software, is that when I have more than 10 different items on the list, I can't scroll to the first ones. But besides that, I am very happy in going on with buying your parts.

Frequently Asked Questions
What is the Caterpillar 6Y3394 pin used for?
The 6Y3394 is a precision pin used in linkage, pivot, and connection assemblies on Caterpillar equipment. Pins transmit load between connected components and allow controlled articulation. They are common in bucket linkages, blade pivot points, cylinder attachments, and structural joints.
How do I measure whether a pin is worn and needs replacing?
Use an outside micrometer to measure the pin diameter and compare it against the nominal size and wear limit specified in the Caterpillar service manual. Also check the bore diameter of the mating bushing. If the clearance between pin and bushing exceeds the published wear limit, both components should be replaced.
Should the bushing be replaced at the same time as the pin?
Yes ??? pins and bushings wear as a matched pair. Installing a new pin in a worn bushing (or vice versa) results in accelerated wear of the new component and a shortened service life for the repaired joint. Replace both at the same time for the best outcome.
What models is the 6Y3394 pin compatible with?
This pin is used across multiple Caterpillar equipment applications. Confirm compatibility against your machine's documentation. If you are still unsure, reach out to Propel Parts ??? our team will be happy to help you verify if this part fits your equipment.
How is this pin installed and retained in the joint?
The 6Y3394 pin is typically installed by pressing or driving it into the bore and secured with a retaining ring, cotter pin, or bolt. Refer to the Caterpillar service manual for the specific retention method and torque specifications for the fastening hardware.
Are seals used with this pin to retain grease or exclude contaminants?
Many pin assemblies include seals or O-rings to retain grease and exclude water and abrasives. If the joint uses seals, replace them whenever the pin is removed. Browse our seals and gaskets for heavy equipment for compatible sealing options.
