Assembly; Engine Block - Ford Ranger Maintaince And Repair Manual

Certain cracks can be repaired in both cast iron and aluminum heads. For cast iron, a tapered threaded insert is
installed along the length of the crack. Aluminum can also use the tapered inserts, however welding is the
preferred method. Some physical damage can be repaired through brazing or welding. Contact a machine shop
to get expert advice for your particular dilemma.

ASSEMBLY

The first step for any assembly job is to have a clean area in which to work. Next, thoroughly clean all of the
parts and components that are to be assembled. Finally, place all of the components onto a suitable work space
and, if necessary, arrange the parts to their respective positions.
Except the 2.3L, 2.5L and 4.0L SOHC (VIN E) Engines
1. Lightly lubricate the valve stems and insert all of the valves into the cylinder head. If possible,
maintain their original locations.
2. If equipped, install any valve spring shims which were removed.
3. If equipped, install the new valve seals, keeping the following in mind:
♦ If the valve seal presses over the guide, lightly lubricate the outer guide surfaces.
♦ If the seal is an O−ring type, it is installed just after compressing the spring but before the
valve locks.
4. Place the valve spring and retainer over the stem.
5. Position the spring compressor tool and compress the spring.
6. Assemble the valve locks to the stem.
7. Relieve the spring pressure slowly and insure that neither valve lock becomes dislodged by the
retainer.
8. Remove the spring compressor tool.
9. Repeat Steps 2 through 8 until all of the springs have been installed.
