SERVICE PROCEDURE
Clutch Hydraulic Fluid Flush/Removal and Refill Procedure
CAUTION:


Make sure the clutch fluid level in the reservoir tank (reservoir) does not become empty.



Cover fenders and painted areas to protect them from possible clutch/brake fluid splashing.



If clutch/brake fluid is spilled on any painted surface, immediately wipe off with a soft cloth and wash
with water.



Keep contamination from entering the reservoir. Appropriately clean out all contamination immediately.

NOTE:


This procedure requires two (2) technicians to properly flush and refill the clutch hydraulic
system.



Do not use a vacuum assist or any other type of power bleeder on this system. Use of a vacuum
assist or power bleeder will not purge all the air from the system.



Store brake fluid in an area that is dark, low humidity, and cold.



Refill the reservoir slowly and directly from the original container.



If air bubbles are created when filling the reservoir, wait until they disappear before bleeding.
