Next, affix the lower two (2) alternator mounting points to the alternator bracket as shown in Figure 3d. Some applications may require the use of the two (2) supplied short, black spacers between the alternator and bracket as shown in Figure 3e.

There are two (2) different flange thicknesses on K-series alternator for the lower two mounting bolts. If you have a 30 mm (1.18in) flange, use the supplied 55 mm M8x1.25 bolts. If you have a 40 mm (1.57in) flange, use the supplier 65 mm M8x1.25 bolts. See the table below to see if you should use them.

DO NOT use the lower spacers if your application does not require them.
