Product Questions

Frequently Asked Questions

What is the 3B4617 pin used for?

The 3B4617 is a pin used to join or align components, carrying shear load and maintaining correct positioning in the assembly.

How do I install the 3B4617 pin?

To install the 3B4617 properly, prepare the area first and confirm the result afterward. Use these steps:

  1. Shut the machine down and support the assembly before service
  2. Drive or press out the old pin and inspect the bores
  3. Clean and check the bores for wear or ovality
  4. Fit the 3B4617 with the correct orientation and retention
  5. Confirm the joint moves correctly and is properly secured

Which Caterpillar machines is the 3B4617 compatible with?

Compatibility for the 3B4617 pin varies by machine and configuration, so cross-check it for your Caterpillar equipment before ordering. Check your manual or reach out to Propel Parts for help verifying fitment.

Does the 3B4617 pin meet performance standards?

Yes. The 3B4617 is engineered to meet OEM specifications for material, dimensions, and durability. When replacing, choose genuine or high-quality aftermarket parts that meet or exceed OEM specifications so the part performs the way it was designed to.

How often should the 3B4617 be replaced?

The 3B4617 is typically renewed during scheduled service or a related repair. In demanding, high-hour operation, inspect it more often to stay ahead of wear.

What are the signs of a worn or failing 3B4617 pin?

A worn 3B4617 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 3B4617 important, and what related parts work with it?

A sound 3B4617 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 6V4364 Ring Retaining and 7K9686 Bearing Sleeve.
