26. Turn the engine on the work stand so that the front end is up. Install the timing
chain, sprockets, front cover, new oil seal and crankshaft pulley. Turn the engine
on the work stand so that the rear end is up. Install the rear oil seal.
27. Clean the oil pan, oil pump and the oil pump screen assembly.
28. Prime the oil pump by filling the inlet opening with oil and rotating the pump shaft
until the oil emerges from the outlet opening. Install the oil pump, baffle and oil
pan.
29. Position the flywheel on the crankshaft. Tighten to 54-64 ft. lbs. (73-87 Nm).
30. Turn the engine on work stand so that the engine is in the normal upright position.
Install the accessory drive pulley. Install and adjust the accessory drive belts to
specification.
31. Install the torque converter, as required.
32. Remove the engine from the work stand. Install the engine in the vehicle.
3.8L Engine
If the bearings are to be reused, they should be identified to ensure that
they are installed in their original positions.
1. Disconnect the negative battery cable, then drain the engine oil. Remove the
engine from the vehicle and mount it on a suitable work stand.
2. Tag and disconnect the ignition wires from the spark plugs, then remove the
distributor cap and ignition wires as an assembly. Remove the spark plugs.
3. On Taurus Police vehicles, remove the oil pan baffle.
4. Remove the oil pan and oil pickup tube.
5. Remove the front cover and water pump as an assembly.
6. Remove the distributor drive gear,.
7. Remove the camshaft and crankshaft sprockets and the timing chain.To do this:
pull back on the ratcheting mechanism of the timing chain vibration damper, then
install the pin through the hole to relieve the tension against the chain.
8. Remove the flywheel and the engine rear cover.
9. Remove the connecting rod bearing nuts and caps. Identify each bearing cap to
insure that they are installed in their original positions. Push the pistons up into
the cylinder and put pieces of rubber hose on the connecting rod bolts so the
crankshaft journals do not get damaged.
10. Inspect all the machined surfaces on the crankshaft for nicks, scratches, scores,
etc., which could cause premature bearing wear.
Because the engine crankshaft incorporates deep rolling of the main
journal fillets, journal refinishing is limited to 0.25mm undersize. Further
refinishing may result in fatigue failure of the crankshaft. Ensure the
bearing inserts and the bearing bores are clean. Foreign material under
the inserts will distort the bearing and cause a failure.
11. Remove the main bearing caps and identify each bearing cap to insure that they
are installed in their original positions.
12. Carefully lift the crankshaft out of the block to prevent damage to bearing
surfaces. Remove rear oil seal and discard. Before installation, lightly oil all bolt
and stud threads.
