Repair 7

Disconnect the cable from the negative battery terminal with a socket wrench to avoid starting the engine during the crankshaft balancer installation. Turn the drive belt tensioner counterclockwise to relieve the tension on the drive belt. Detach the drive belt from the crankshaft pulley.

Remove any additional components needed to access the crankshaft. This can include the shroud for the cooling fan, the cooling fan and the radiator, depending on the specific Oldsmobile model.

Disconnect the attaching bolt for the crankshaft damper with a socket wrench. Attach a puller to the crankshaft damper, and pull the damper from the crankshaft. Release the puller from the damper.

Mount the new crankshaft damper to the crankshaft, and fasten the mounting bolt for the damper with a socket wrench.

Install the components you removed in step two to access the crankshaft. Mount the drive belt to the crankshaft pulley, and turn the belt tensioner clockwise to apply tension to the drive belt. Connect the cable to the negative battery terminal with a socket wrench.

Hold the flywheel in place with a flywheel locking tool, and detach the drive belts from their pulleys. Disconnect the mounting bolt for the crankshaft balancer with a socket wrench.

Mark the crankshaft balancer and the crankshaft with white paint to indicate the correct position of the crankshaft balancer. Attach a puller to the crankshaft balancer, and pull it from the crankshaft.

Record the position of the weights on the crankshaft balancer. Remove the washer and weights from it.

Mark the new crankshaft balancer with white paint using the mark on the old balancer as a guide. Mount the weights in the new crankshaft balancer according to the notes made in the previous step. Install the washer on the new crankshaft balancer.

Place the new crankshaft balancer on the end of the crankshaft. Attach the balancer installer "J-41665" to the crankshaft seal installer "J-41478". Place the small end of the installer assembly into the balancer.

Hold the hex end of the threaded rod for the installer assembly with a box-end wrench. Turn the nut on the installer assembly clockwise with a second box-end wrench to mount the crankshaft balancer onto the crankshaft.

Remove the small end of the installer assembly from the crankshaft balancer, and place the large end of the installer assembly against the balancer to seat it onto the crankshaft. Remove the installer assembly from the crankshaft.

Fasten the old mounting bolt in the crankshaft balancer, and tighten it to 240 foot-pounds with a torque wrench. Remove the old mounting bolt with a socket wrench. Use a depth micrometer to ensure the crankshaft nose is recessed to between 0.094 and 0.176 inch within the balancer bore.

Fasten the new mounting bolt for the crankshaft balancer, and tighten it to 37 foot-pounds with a torque wrench. Tighten the mounting bolt an additional 140 degrees with a socket wrench.

Attach the drive belts to their pulleys. Detach the flywheel locking tool from the flywheel.

Remove the negative battery cable with a socket wrench to prevent the engine from starting accidentally. Detach the accessory drive belt from the crankshaft pulley.

Raise the vehicle with a floor jack, and support it on jack stands. Remove the right front wheel with a lug wrench.

Hold the flywheel in place with flywheel locking tool "J-37096". Disconnect the mounting bolt for the crankshaft with a socket wrench.

Mount the balancer remover "J-38107-A" to the crankshaft balancer, and fasten 1/4-inch bolts to the pulley. Tighten the bolts with a socket wrench to remove the balancer from the crankshaft.

Coat the sealing surface of the crankshaft balancer with a light layer of engine oil. Mount the balancer onto the crankshaft, and hold the flywheel in place with flywheel locking tool "J-37096". Tighten the mounting bolt for the crankshaft balancer to 111 foot-pounds with a torque wrench. Tighten the bolt another 76 degrees with a socket wrench.

Replace the right front wheel with a lug wrench, and lower the vehicle. Attach the drive belt to the crankshaft pulley and connect the cable to the negative terminal of the battery.

Spray penetrating oil on the end of the broken bolt. Allow the penetrating oil to soak in around the bolt for five to six hours.

Align the tip of a center punch with the center of the broken bolt. Hit the center punch with a hammer to make a depression on the end of the broken bolt.

Secure a 1/8-inch left-hand drill bit in the chuck of a drill motor. Drill a hole at least 1/2-inch deep in the end of the bolt, using the center punch depression as a guide to hold the drill bit in place. Exchange the 1/8-inch drill bit for the drill bit recommended by an EasyOut set for the size of the broken bolt. Enlarge the hole with the larger drill bit.

Set the squared end of the recommended EasyOut into the tee-handle wrench supplied with the set. Tighten the handle of the wrench to hold the EasyOut in place.

Place the tapered end of the EasyOut in the drilled hole running through the center of the broken bolt. Turn the tee-handle wrench counterclockwise to force the EasyOut into the hole. Continue turning the wrench until the broken section of the bolt backs out of the threaded hole.

Remove the battery cable from the negative terminal with a socket wrench to avoid starting the engine accidentally. Raise the vehicle on a floor jack, and support it safely on jack stands.

Disconnect the serpentine drive belt from the crankshaft pulley with a socket wrench.

Hold the hub of the crankshaft in place by using a straight piece of metal as a pry tool. Remove the retaining bolts from the hub with a socket wrench, and detach the crankshaft balancer from the crankshaft hub.

Mount the new crankshaft balancer onto the crankshaft hub, and fasten the retaining bolts for the crankshaft balancer. Hold the crankshaft hub in place with the pry tool, and tighten the retaining bolts for the crankshaft balancer to 63 foot-pounds with a torque wrench.

Mount the serpentine drive belt on the crankshaft pulley, and lower the vehicle with a floor jack. Connect the cable to the negative battery terminal.
