PRECAUTIONS

Service Notice or Precautions for Clutch

INFOID:0000000001731680

CAUTION:

• Recommended clutch fluid is brake fluid “DOT 3”. Refer to 

MA-10, "Fluids and Lubricants"

.

• Never reuse drained clutch fluid.
• Never splash clutch fluid on painted areas.
• When removing clutch tube, use a flare nut wrench.
• When installing clutch tube, use a flare nut torque wrench.
• Use new clutch fluid to clean or wash all parts of master cylin-

der.

• Never use mineral oils such as gasoline or kerosene. It will

ruin the rubber parts of the hydraulic system.

• If transmission assembly is removed from the vehicle, always

replace CSC (Concentric Slave Cylinder) body and CSC tube.
Return CSC body insert to original position to remove trans-
mission assembly. Dust on clutch disc sliding parts may dam-
age seal of CSC body and may cause clutch fluid leakage.

• Never disassemble CSC body.

WARNING:

After cleaning clutch disc, wipe it with a dust collector. Never use compressed air.
