Fig. 130 Removing Dowel With Special Tools

Smooth seal compound around toward outer edge and allow to dry (approximately one minute). CAUTION: In no case will fiber gasket be used between flywheel and crankshaft flange. Use only Pliobond 30 seal compound in all cases.

    6. Install flywheel on crankshaft flange carefully and enter all flywheel bolts through plates. Tighten bolts diametrically opposite in uniform manner to 165 lb. ft. torque. NOTE: Draw flywheel on evenly during this operation to prevent leakage and excessive runout.

    7. Mount indicator so stem or button rests on torus cover gasket seal area and check flywheel runout. Runout should not exceed .005" total indicator reading (Fig. 131).

    8. Ream dowel hole for oversize (service) dowel, using tool J-2774-12, J-2774-14,
