Insert Guide (499747000 for 2WD or 499747100 for 4WD) into clutch disc and install them on flywheel by inserting end of guide into pilot bearing. Install clutch cover on flywheel and tighten bolts to 11-13 ft. Lbs. (14-17 N.M).

3. When installing clutch cover on flywheel, position clutch cover so there is a gap of 120° or more between "0" marks on flywheel and clutch cover. Note front and rear of clutch disc when installing. Tighten clutch cover installing bolts gradually. Each bolt should be tightened in a criss-cross fashion to specified torque.

4. After remounting engine and transmission on body, make adjustment with nut at lever end so clutch release lever end play is.08-.12" (2-3 mm) for 2WD non-turbo and.12-.16" (3-4 mm) for all others.
