Great pricing and fast shipping!
I'll admit that I was skeptical of propel parts, but they are an honest site and came through with the order. I was skeptical because I've never ordered heavy machinery parts, and didn't know who to trust. The parts that I ordered showed in stock, but after checking with their vendor, they only had half of the order in stock. I was notified the day after the order, and most of the parts arrived in a few days. There was one part that was not shipped putz but I was able to talk with who I assumed is the owner who rectified the situation and had the part overnighted to me.
I will say that communication speed could use a little work, but they will eventually get back with you.

Awesome quality products! Better customer service! Steven is always a pleasure to work with and very prompt in assisting me - thank you!
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.

Product Questions
Frequently Asked Questions
What is the Caterpillar 3B4510 plain lockwasher used for?
The 3B4510 plain lockwasher is a flat washer designed to sit under a nut or bolt head in Caterpillar equipment. It helps distribute load evenly, protect mating surfaces, and reduce loosening by improving contact between the fastener and the part being secured. This contributes to secure and reliable fastening in heavy machinery assemblies.
How does a plain lockwasher differ from a split lockwasher?
A plain lockwasher like the 3B4510 is a flat washer used to distribute load and protect surfaces, while a split (helical) lockwasher adds locking tension to help resist vibration‑induced loosening. Both have their place in equipment assemblies, and the specific design used depends on the application and torque requirements.
Which Caterpillar machines commonly use the 3B4510 lockwasher?
The 3B4510 washer is compatible with various Caterpillar machines including motor graders, excavators, loaders, and engine assemblies that require flat washers for proper fastening. Its use is typically specified in the service manual for applications where load distribution and surface protection are needed. Always confirm fitment using your machine model and serial number.
Is the 3B4510 lockwasher an OEM‑quality replacement part?
Definitely. The 3B4510 replacement is manufactured to meet OEM performance standards, making it a reliable choice for demanding heavy equipment applications. Contact Propel Parts if you need help confirming it\'s the right part for your setup.
How do I install a plain lockwasher like the 3B4510?
Installation is simple: place the 3B4510 lockwasher between the fastener head (or nut) and the surface being secured, then tighten the bolt or nut to the specified torque. The washer helps spread the load, which can protect the surface and support proper tightening across the assembly.
What are signs that a plain lockwasher needs replacement?
A plain lockwasher should be replaced if it shows any of the following:
- Visible wear or deformation
- Corrosion or rust buildup
- Cracks or bending
- Loose connections after torqueing
Replacing worn washers during routine service helps keep fasteners secure and prevents equipment failures.
Why is using the correct lockwasher important in Caterpillar equipment?
Using a 3B4510 that matches OEM specifications ensures it integrates correctly into the system, maintaining proper sealing, load distribution, or mechanical function. Incorrect parts can lead to premature failure and damage to adjacent components.
