Clutches Acura Integra III

IDENTIFICATION

TRANSAXLE APPLICATIONS

DESCRIPTION

All clutches use diaphragm spring to engage the pressure plate and is equipped with a hydraulic release system.

BLEEDING CLUTCH HYDRAULIC SYSTEM

Attach hose to bleeder fitting located on clutch release cylinder, next to hydraulic line. Submerge other end of hose in container half full of clean brake fluid. Fill reservoir with DOT 3 or DOT 4 brake fluid. Open bleeder fitting. Have assistant press clutch pedal to full release position. Close bleeder fitting. Release clutch pedal. Repeat until air bubbles no longer emerge from hose. Refill reservoir.

ADJUSTMENTS

Note. Hydraulic clutches do not require periodic adjustment for free play. (Scheme 1)

All Models

1. Loosen lock nut "A". (Scheme 1) Loosen clutch switch until plunger no longer touches clutch pedal. Loosen lock nut "C". Rotate clutch pedal push rod to obtain specified pedal travel and height. Tighten lock nut "C".
2. Turn clutch switch inward until it contacts clutch pedal, then turn it in another 1/4 - 1/2 turn (3/4 - 1 full turn on Integra). Tighten lock nut "A".
3. Loosen lock nut "B". (Scheme 1) Loosen clutch interlock switch. Measure clearance between floorboard and clutch pedal with clutch pedal fully depressed. Release clutch pedal.59-.79" (15-20 mm) from fully depressed position and hold it there.
4. Adjust position of clutch interlock switch so engine will start with clutch pedal at this position. Turn clutch interlock switch inward an additional 3/4 - 1 turn. Tighten lock nut "B".

REMOVAL & INSTALLATION

Note. If vehicle is equipped with an anti-theft radio, obtain code number before disconnecting battery. After service, turn ignition and radio on. When CODE appears, enter code using radio station preset buttons to restore radio operation.

Removal (Integra)

1. Remove battery and battery tray. Remove air cleaner housing and air inlet duct as an assembly. Disconnect ground cable from transaxle. Remove lower radiator hose clamp from transaxle hanger.
2. Unplug connector from back-up light switch. Drain transaxle fluid. Remove vehicle speed sensor connector. Disconnect cables and wiring harness clamp from starter. Remove hydraulic hose bracket and clutch slave cylinder.
3. Remove 3 upper transaxle mounting bolts and lower starter bolts. Remove engine splash shield. Disconnect oxygen sensor connector. Remove exhaust pipe from catalytic converter and manifold. On models with VTEC engines, remove catalytic converter. On all models, separate lower right ball joint from control arm. Remove right damper fork. Remove axle shafts and intermediate shafts. See appropriate AXLE SHAFTS article in AXLE SHAFTS & TRANSFER CASES.
4. Remove heat shield. Disconnect shift rod and torque rod from transaxle. Remove front and rear engine braces. Remove clutch housing cover. Remove right front transaxle mount/bracket. Place floor jack under transaxle. Support engine with jack stands. Remove transaxle mount.
5. Remove rear transaxle mount bracket and mount bolts from side of transaxle. Check for wires, hoses, or any other components that may still be attached. Move transaxle away from engine until shaft clears clutch. Lower transaxle to remove from vehicle.
6. Before removing clutch from flywheel, measure diaphragm spring fingers wear with feeler gauge, Handle (07936-3710100), Clutch Alignment Shaft (07NAF-PR30100), and Clutch Alignment Disc (07JAF-PM7011A). Wear limit is 0.03" (0.8 mm). Install flywheel holder. If reusing clutch, mark pressure plate and flywheel for installation reference. Unscrew pressure plate bolts 2 turns at a time in a crisscross pattern, to prevent warpage.

Inspection (Integra)

1. Inspect pressure plate surface for wear, cracks, burning or warpage in excess of .006" (.15 mm). Measure warpage with straightedge and feeler gauge at several points. Inspect clutch pilot and release bearing for smooth operation and looseness. Replace bearings if necessary.
2. Inspect clutch disc lining for excessive wear and burned or oil-soaked condition. Measure disc thickness and rivet depth. Inspect clutch disc for loose torsion dampers. Measure clutch disc and flywheel runout. Replace clutch disc if not within specifications. See «CLUTCH SPECIFICATIONS»(/acura/integra/iii-1993-2001/remont/clutches-manual-hydraulic/#clutches) table.
3. Inspect flywheel ring gear teeth for wear and damage. Inspect flywheel for wear, cracks and burned condition. When measuring flywheel runout, push against flywheel to take up crankshaft thrust washer clearance.

Note. Use new set rings (spring clips) on both axle shafts. Slide axles in until set rings engage differential.

Installation (Integra)

1. Tighten flywheel bolts to specification in a crisscross pattern. Align dowel holes in pressure plate with flywheel dowels. Using clutch alignment tool and ring gear holder, install disc and pressure plate. Tighten pressure plate bolts to specification in a crisscross pattern. See appropriate «TORQUE SPECIFICATIONS»(/acura/integra/iii-1993-2001/remont/clutches-manual-hydraulic/#clutches) table.
2. Ensure both dowel pins are installed in clutch housing. Clean release bearing sliding surface. Apply molybdenum disulfide grease to surface. Apply a light coat of grease to input shaft splines. Keep clutch disc and pressure plate surfaces free of grease and dirt.
3. To complete installation, reverse removal procedure. Tighten transmission mount bolts in sequence as illustrated. (Scheme 2) Refill all fluids to proper level. Adjust clutch pedal height and free play. See «CLUTCH PEDAL TRAVEL & HEIGHT»(/acura/integra/iii-1993-2001/remont/clutches-manual-hydraulic/#clutches) under ADJUSTMENTS.

Removal (2.2CL & 2.3CL)

1. Remove battery and battery tray. Remove air cleaner housing and air inlet duct as an assembly. Drain transaxle fluid. Disconnect cables and wiring harness clamp from starter. Unplug connector from back-up light switch. Remove vehicle speed sensor connector.
2. Shift transmission into Reverse. Disconnect shift cable from transaxle. Remove clutch damper bracket. Remove clutch slave hydraulic hose bracket and slave cylinder. Remove 2 upper transaxle mounting bolts. Remove engine splash shield. Separate lower ball joints from control arms. Remove damper forks. Remove right radius arm. Remove axle shafts and intermediate shafts. See appropriate AXLE SHAFTS article in AXLE SHAFTS & TRANSFER CASES.
