While internal alternator repairs are possi ble, they require specialized tools and
training. Therefore, it is advisable to replace a defective alternator as an
assembly, or have it repai red by a qualified shop.
1. Disconnect the battery ground cable.
2. Tag and disconnect the alternator wiring.
3. Remove any drive belt(s) which may interfere with alternator removal.
4. Support the alternator and remove the mount bolt(s). Remove the unit
from the vehicle.
To install: 5. Position the alternator into place and install the mount bolt(s) loosely.
6. Install the drive belt(s). On V- belts, tighten the belt enough to allow
approximately
1/2 in. (13mm) of play on the longest run between pulleys.
7. Connect the alternator wiring.
8. Connect the battery ground cable.

2. Remove the 4 through-bolts and s eparate the drive end frame assembly
from the rectifier end frame assembly.
3. Remove the 3 diode trio attachi ng nuts and the 3 regulator attaching
screws.
4. Remove the diode trio and the regulator from the end frame.

Before attempting to repair a threaded
hole, remove any snapped, broken or
damaged bolts or studs. Penetrating oil ca n be used to free frozen threads. The
offending item can usually be removed with locking pliers or using a screw/stud
extractor. After the hole is clear, the thread can be repaired, as shown in the
series of accompanying illustrations and in the kit manufacturer's instructions.
ENGINE PREPARATION
To properly rebuild an engine, you must fi rst remove it from the vehicle, then
disassemble and diagnose it. Ideally you should place your engine on an engine
stand. This affords you the best access to the engine components. Follow the
manufacturer's directions for using the stand with your particular engine.
Remove the flywheel or fl explate before installing the engine to the stand.
Now that you have the engine on a stand, and assuming that you have drained
the oil and coolant from the engine, it's ti me to strip it of all but the necessary
components. Before you start disassembli ng the engine, you may want to take
a moment to draw some pictures, or fabr icate some labels or containers to mark
the locations of various components and the bolts and/or studs which fasten
them. Modern day engines use a lot of littl e brackets and clips which hold wiring
harnesses and such, and these holders are often mounted on studs and/or bolts
that can be easily mixed up. The manufacturer spent a lot of time and money
designing your vehicle, and they wouldn't have wasted any of it by haphazardly
placing brackets, clips or fasteners on t he vehicle. If it's present when you
disassemble it, put it back when you asse mble, you will regret not remembering
that little bracket which holds a wire har ness out of the path of a rotating part.
You should begin by unbolting any accessories still attached to the engine, such
as the water pump, power steering pump, alternator, etc. Then, unfasten any
manifolds (intake or exhaust) which were not removed during the engine
removal procedure. Finally, remove any covers remaining on the engine such
as the rocker arm, front or timing cove r and oil pan. Some front covers may
require the vibration dam per and/or crank pulley to be removed beforehand.
The idea is to reduce the engine to the bar e necessities (cylinder head(s), valve
train, engine block, crankshaft, pistons and connecting rods), plus any other 'in
block' components such as oil pumps, balance shafts and auxiliary shafts.
Finally, remove the cylinder head(s) from the engine block and carefully place
on a bench. Disassembly instructions fo r each component follow later in this
section.
CYLINDER HEAD
There are two basic types of cylinder heads used on today’s automobiles:
the Overhead Valve (OHV) and the Over head Camshaft (OHC). The latter can
also be broken down into two subgr oups: the Single Overhead Camshaft
(SOHC) and the Dual Overhead Camshaft (DO HC). Generally, if there is only a
single camshaft on a head, it is just referred to as an OHC head. Also, an
engine with a OHV cylinder head is also known as a pushrod engine.
