Had a great experience with ordering correct engine gaskets for our 3208 caterpillar engine
-
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 3B5322 pin used for?
The 3B5322 is a pin used to join or align components, carrying shear load and maintaining correct positioning in the assembly.
How do I install the 3B5322 pin?
A reliable installation of the 3B5322 starts with inspection and ends with verification. Follow this process:
- 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 3B5322 with the correct orientation and retention
- Confirm the joint moves correctly and is properly secured
Which Caterpillar machines is the 3B5322 compatible with?
Fitment for the 3B5322 depends on your specific Caterpillar model and the assembly it serves, so confirm the application before you order. Or reach out to Propel Parts for help verifying fitment.
Does the 3B5322 pin meet performance standards?
Yes. The 3B5322 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 3B5322 be replaced?
Plan to replace the 3B5322 during a rebuild of the surrounding components, or sooner if inspection shows it is past its serviceable limit. The 1S3311 Ring Retaining is often renewed during the same service, so many technicians replace both at once to reduce downtime.
What are the signs of a worn or failing 3B5322 pin?
Catching a failing 3B5322 early prevents wider damage. The common warning signs include:
- 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 3B5322 pin important, and what related part is commonly replaced with it?
Keeping the 3B5322 in good condition protects the components around it and supports smooth, reliable operation. Maintaining the assembly with parts that meet OEM specifications helps you avoid unplanned downtime. For a complete repair, the 2K4510 Bushing is another component from the same assembly that is commonly replaced at the same time.
