How do you properly remove and reinstall the crankshaft hub and pulley in four cylinder engine on Chevrolet Astro?

First, disconnect the cable from the negative terminal of the battery and if the car has the feature applicable to the audio system then turn off the anti-theft alarm system. Subsequently, take out the drivebelts and make sure you label them especially if you are doing a replacement so you can put them back in their respective places. Lift the vehicle and support using jackstands. As for c ars that have the manual transmission, set the parking brakes and set the gear shift of the car to neutral; this will prevent the engine from turning over while you remove the crankshaft pulley bolts. In automobiles with automatic transmission, some modifications may be required such as; the removal of the starter motor and immobilization of the starter ring gear using a large screwdriver while the other person loosens the bolts of the pulley. To ease the crankshaft hub retaining bolt, place another bolt on one of the pulley bolt holes, secure a breaker bar, extension and socket on the crankshaft hub retaining bolt and keep the hub from rotating by inserting a large screwdriver alongside the bolt and socket before turning the bolt anticlockwise to remove it. Take out the crankshaft hub if you can, using a puller if that's needed. Coat a thin layer of moly-base grease to the sealing area of the pulley hub; slide the crankshaft pulley hub until it reaches the bottom most position stop against the crankshaft timing gear sprocket with the slot on the pulley hub facing the Woodruff key way. The hub retaining bolt can be used to force the hub into the right position as required when fitting the new hub. Screw the hub-to-crankshaft bolt to the recommended torque, fit the crankshaft pulley to the hub, engaging the threads of the bolt with Loctite, then re-engage the drivebelts.
