The puller is installed using the same thread bolts that secured the bottom pulley. The procedure shown is for most engines up until the LS-series Chevy and the Gen 3 Hemi, etc. | The puller is installed using the same thread bolts that secured the bottom pulley.

| − | + | Start out with the puller center screw lubricated well. The crank will have a recess for the puller shaft nose to index on. | |

| + | On the Chevy V8 the bottom pulley bolt thread size is 3/8-24. Most engines will be either 5/16-18 or 5/16-24 or 3/8-16 or 3/8-24. You won't be able to use the original pulley bolts; most puller sets come with an assortment of bolts, otherwise find three that are the same length and long enough to use the puller. | ||

| + | Take the bolts down evenly so the puller is centered on the snout then use a breaker bar to tighten the puller. The crank may try to turn once the puller is tight; you can run a prybar through the puller bolts to hold the engine from turning, or get a helper under the vehicle to hold the flexplate or flywheel. If it's a manual trans you can put it in gear and set the parking brake and block the wheels to keep the engine from turning over. | ||

| + | Don't be tempted to use an impact wrench on the puller. This will damage the threads if over done. Keep turning the center screw of the puller until you feel/see the damper start to back off the crank. Once it starts, most of the time it will come off the rest of the way easily. Don't let the damper drop onto the floor. | ||
| + | |||
| + | Once the damper is off, remove the puller bolts and store the tool away for the next time. If the damper is to be reused, clean it off first, coat the snout inside and out with motor oil and store away from rain, etc. | ||
