Clutch fluid should never need to be added or removed as the result of normal wear.

At every service, check moisture content of fluid using DOT 4 BRAKE FLUID MOISTURE TESTER (Part Number:HD-48497-A). Follow the instructions included with tool.

Flush clutch system and replace DOT 4 fluid every two years or sooner if brake fluid test shows moisture content is 3% or greater.

If the clutch does not operate properly, refer to the service manual or see a Harley-Davidson dealer for service.
