Frequently Asked Questions
What is the Caterpillar 3B4512 lockwasher used for?
The 3B4512 lockwasher is designed to secure bolts and fasteners in Caterpillar equipment assemblies. Its split-spring design helps maintain tension on the fastener, preventing bolts from loosening due to vibration, heavy loads, or continuous equipment operation.
What are the key specifications of the 3B4512 lockwasher?
The 3B4512 lockwasher typically features an inside diameter of approximately 0.761–0.791 inches, an outer diameter of about 1.010 inches, and a thickness of around 0.188 inches. These dimensions allow it to provide strong locking support for heavy-duty fasteners used in Caterpillar machinery.
Is the 3B4512 lockwasher an OEM-spec replacement part?
Yes. Many suppliers manufacture the 3B4512 lockwasher to meet U.S. OEM specifications, ensuring the same durability, fit, and performance as the original Caterpillar component used in equipment assemblies.
Why are lockwashers important in heavy equipment?
It does. The 3B4512 is designed to meet or exceed OEM specifications, providing consistent performance in the applications it was built for. Have questions about your specific machine? Reach out to Propel Parts for guidance.
How can I confirm if the 3B4512 lockwasher fits my Caterpillar machine?
To verify compatibility, check the equipment model, serial number, or existing part number. Many parts suppliers also confirm fitment using CAT SIS (Caterpillar Service Information System) before shipping to ensure the lockwasher matches your machine.
When should the 3B4512 lockwasher be replaced?
You should replace the lockwasher if it shows signs of wear, corrosion, deformation, or reduced spring tension. Replacing worn lockwashers during maintenance helps maintain secure fasteners and prevents unexpected equipment issues.
