Product Questions
Frequently Asked Questions
What is the Caterpillar 9R0109 washer and what does it do?
The 9R0109 washer is a precision hardware component that distributes bolt load, prevents fastener embedment into softer materials, and provides a stable, flat bearing surface for bolted joints across various Caterpillar equipment assemblies.
How do I confirm this is the correct washer for my application?
Match the part number (9R0109) to your machine's parts manual or the assembly drawing for the component being serviced. Also confirm the outer diameter, inner diameter, and thickness match the joint requirements. Check your manual or reach out to Propel Parts for help verifying fitment.
Can a washer affect the clamping force of a bolted joint?
Yes ??? a washer that is too thick or too thin changes the effective joint stack height, which can affect the torque-to-clamp-force relationship. Always use the specified washer to maintain the designed clamping preload in the assembly.
Is this washer made from hardened steel?
The material specifications for the 9R0109 are outlined in the product listing. Hardened washers are required in applications where standard washers would deform under load. Using the correct hardness grade is critical in high-stress bolted joints.
Should sealing washers be considered for hydraulic or fuel line fittings?
In applications where fluid sealing is also needed, a sealing washer with an integrated O-ring or soft-metal face may be required in addition to or instead of a standard flat washer. Browse our O-ring seals catalog if you also need sealing components for the same service job.
What models does the 9R0109 washer fit?
This washer is used across multiple Caterpillar machine families. Confirm compatibility using your machine's service documentation or contact the Propel Parts team for guidance.
What warranty does Propel Parts offer on this washer?
All hardware components including the 9R0109 washer carry a 1-year warranty at Propel Parts. Same-day weekday shipping and a 30-day return policy are standard on all orders.
