Quick and prompt support. Easy to work with. They had the parts in stock which is even better. Great pricing.
-
At the beginning, I experienced significant delays and communication issues regarding my order, which honestly caused serious concern because the parts were urgently needed for an important project.
However, after continuous follow-up, the Propel Parts team handled the matter professionally, provided shipment tracking, and the parts finally arrived successfully.
I especially appreciate their willingness to communicate, acknowledge the issue, and continue working toward resolving the situation.
In international business, delays can sometimes happen, but what matters is the final commitment to resolving the issue properly.
Thank you to Daniel and the team, and hopefully future transactions will be smoother for both sides. -
I would give 5 stars but my first time ordering from here and using aftermarket parts. The price is reasonable comparing to original Cat parts and the customer support is great and hoping to do more business with them

Propel Parts provided quality parts for my Caterpillar needs at a very fair price. Shipping to my international location was very fast. took about a week for the parts to get here. Seller is also responsive with my inquiry.
Thanks again -
Buen servicio y atención
Frequently Asked Questions
What is the 5P3930 bearing used for?
The 5P3930 is a bearing that supports rotating or sliding motion while keeping friction and wear low, protecting the parts it carries.
How do I install the 5P3930 bearing?
A reliable installation of the 5P3930 starts with inspection and ends with verification. Follow this process:
- Shut down and let the assembly cool, then follow safe service procedures
- Remove the old bearing and inspect the journal or housing
- Clean all surfaces and check clearances against the manual
- Fit the 5P3930 with the correct orientation and seating
- Lubricate as directed and confirm the assembly turns freely
Which Caterpillar machines is the 5P3930 compatible with?
Fitment for the 5P3930 depends on your specific Caterpillar model and the assembly it serves, so confirm the application before you order. 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.
Does the 5P3930 bearing meet performance standards?
Yes. The 5P3930 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 5P3930 be replaced?
Plan to replace the 5P3930 during a rebuild of the surrounding components, or sooner if inspection shows it is past its serviceable limit. The 1045358 Ring Seal 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 5P3930 bearing?
Catching a failing 5P3930 early prevents wider damage. The common warning signs include:
- Knocking, rumbling, or whining under load
- Excessive play or movement in the assembly
- Metal particles in the oil or on inspection
- Scored, pitted, or discolored bearing surfaces
Why is the 5P3930 bearing important, and what related part is commonly replaced with it?
Keeping the 5P3930 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 2G8615 Washer is another component from the same assembly that is commonly replaced at the same time.
This 5P3930 Needle Bearing is compatible with the following models:
517, 527, 561M, 561N, 572R, 572R II, 578, 583R, 583T, 587R, 587T, 735, 814B, 814F, 814F II, 815B, 815F, 815F II, 816F, 816F II, 936, 936F, 950B, 950B/950E, 950F, 950F II, 950G, 950G II, 950H, 950K & more...
