28.5 Assembly
To reassemble, follow the disassembly sequence in
reverse.
Be sure to observe the following during assembly.
28.5.1 Key points in reassembly
1. When press-fitting the rear bearing into the rear
bracket, heat the rear bracket to 50 to 60°C [122 to
140°F].
2. The brushes must be raised before the rotor is
installed to the rear bracket. To do so, put a wire
through the small hole located on the rear bracket,
then remove the wire after completing the
reassembly.
28.6 Installation
1. Install the fan belt on the alternator, and mount the
alternator on the engine.
Temporarily tighten all the bolts.
2. Insert a bar between the alternator and crankcase.
Using the bar as leverage, move the alternator and
adjust the belt tension.
While keeping the alternator at that position,
tighten the bolt that secures the alternator to the
adjusting plate.
