Frequently Asked Questions
What is the Caterpillar Cotter Pin 9M6505?
The 9M6505 is a cotter pin (also called a split pin) used in Caterpillar equipment assemblies to lock bolts, nuts, clevis pins, and castle nuts in position. Once installed and bent, it prevents the fastener from rotating or backing out during machine operation.
What assemblies use the 9M6505 cotter pin?
Cotter pins are used across many Caterpillar machine assemblies ??? including linkages, steering components, clevis joints, and axle hardware ??? wherever a secondary locking mechanism is required. Check your parts manual or reach out to Propel Parts for help verifying fitment.
Can cotter pins be reused after removal?
No. Cotter pins should never be reused. Once bent into position, the pin is permanently deformed. Reusing a bent cotter pin reduces its locking reliability and risks joint loosening or fastener loss during operation. Always install a new cotter pin during every reassembly.
What material is the 9M6505 cotter pin made from?
The 9M6505 is typically made from low-carbon steel or stainless steel, manufactured to meet or exceed OEM specifications for shear strength, ductility, and dimensional accuracy.
How do I install the 9M6505 cotter pin correctly?
Insert the pin through the hole in the bolt shank or clevis pin shaft. Bend one leg back over the end of the pin and the other leg back against the fastener face ??? or spread both legs apart depending on the application. Ensure the pin is fully seated before bending.
Is the 9M6505 a high-quality aftermarket cotter pin?
Yes. The 9M6505 from Propel Parts is a premium aftermarket cotter pin manufactured to meet or exceed OEM specifications for Caterpillar equipment applications. It is available individually or in quantity for maintenance stock.

What other fasteners should I inspect when replacing a cotter pin?
When installing a new cotter pin, always inspect the mating pin or bolt hole for wear or elongation. A worn or oversized hole will not retain the cotter pin properly and indicates the host component needs replacement.
