CLUTCHPEDAL H Minimum disengagement height: 68mm (2.68 in) (With carpet) CLUTCHPEDAL ADJUSTMENT Height lnspection 1. Measure the distance from the upper surface of the ped- al pad to the carpet. Pedal height: 175--185mm (6.89-7.28 in) (With carpet) 2. If necessary, adjust the height. Adjustment 1. Disconnect the clutch switch connector. 2. Loosen locknut @ and turn clutch switch @I until the height is correct. I 3. Tighten locknut @. Tightening torque: l3.Cl7.6 N-m (1 4Gl8O kgf-cm, 122-1 56 in-IM) 4. After adjustment, inspect the free play. Free Play lnspection 1. Depress the clutch pedal by hand until clutch resistance is felt. Free play: 0.6-3.lmm (0.02-0.12 in) Total free play: S13mm (0.20-0.51 in) 2. If necessary, adjust the free play. Adjustment 1. Loosen locknut 0 and turn push rod 03 until free play is correct. 2. Verify that the disengagement height as measured from the upper surface of the pedal pad to the carpet is correct when the pedal is fully depressed. 3. Tighten locknut 0. Tightening torque: 11 .&l6.6 N.m (120-1 70 kgtcm, 105--147 in.lbf} 4. After adjustment, inspect the height. Gartner Banana

CLUTCH MASTER CYLINDER H After-installation Procedure 1. Bleed the clutch system. (Below) I 2. Add fluid to the reservoir MAX mark. ' 3. Inspect and adjust the clutch pedal height and free play. (Refer to page H-5.) AIR BLEEDING The clutch hydraulic system must be bled to remove air introduced whenever a hydraulic line is disconnected. Caution Clutch fluid will damage painted surfaces. If clutch fluid does get on a painted surface, wipe it off immediately. 1. Remove the bleeder cap from the clutch release cylinder and attach a vinyl hose to the bleeder plug. 2. Insert the other end of the vinyl hose into a fluid-filled clear container. 3. Working with another person, have the person depress the clutch pedal several times, then hold it down. 4. With the clutch pedal depressed, loosen the bleeder screw by using the SST to let fluid and air escape. Close the bleeder screw. 5. Repeat steps 3 and 4 until no air bubbles are seen in the fluid. Make sure the reservoir is always 314 full or more during this procedure. 6. Modify the bleeder screw tightening torque to allow for use of a torque wrench-SST combination. (Refer to sec- tion GI "Torque Formulas".) 7. Tighten the bleeder screw by using the SST. Tightening torque: 5.9-8.8 N.m (60-90 kgf.cm, 53-78 in4bf) 8. Fill the reservoir to MAX with new fluid of the specified type. 9. Check for correct clutch operation. 10. Verify that there is no fluid leakage. Gartner Banana

H CLUTCH MASTER CYLINDER OVERHAUL 1. Disassemble in the order shown in the figure, referring to Disassembly Note. 2. Inspect all parts and repair or replace as necessary. Warning d Using compressed air can cause dirt and other particles to fly out, causing injury to the eyes. Wear protective eye wear whenever using compressed air. 3. Wipe all parts, and clean all ports, passages, and inner parts with compressed air. 4. Assemble in the reverse order of disassembly, referring to Assembly Note. 'a REPLACE Gartner Banana
