- 1). Remove the timing chain cover at the front of the motor. Use a wrench to loosen all the bolts that hold the cover onto the engine. Pull the cover away from the engine and set off to the side. Clean away debris and old gasket that is stuck on the mating surface of the engine and the timing chain cover with utility knife.
- 2). Locate the registration marks on the crankshaft gear and the camshaft gear. These marks are depressed dots and there is one dot on each gear. Rotate the engine until the lower gear's dot is at the twelve o'clock position and the upper gear's dot is at six o'clock.
- 3). Remove the distributor cap and make a note of the position of the rotor. Use a pencil to make an index mark on the engine block and the shaft of the distributor. Pull the distributor out of the motor. Cover the distributor shaft hole with a rag.
- 4). Pull the gear off the crankshaft using a gear pulling tool. Start the two tension bolts of the tool into the threaded holes of the crankshaft gear. Put the center push post of the gear pulling tool onto the end of the crankshaft and begin to tighten the center actuator bolt. As you tighten the actuator bolt of the gear puller it will pull the gear off the end of the crankshaft.
- 5). Gather the gear and unwrap the timing chain from the upper gear of the camshaft. Remove the old timing chain and replace it with a new one. Run one end of the chain over the top gear and then start the bottom gear onto the end of the crankshaft. Align the dot at twelve o'clock and then hit the gear with a hammer to push it back onto the end of the crankshaft.
- 6). Replace the timing chain cover using a new gasket and a wrench to tighten the bolts back in place. Install the distributor in the exact way it was removed. Use the index mark on the distributor shaft and the engine to line the distributor up correctly. Put the distributor back the way it was and the job is complete.
