Step 3:
To reinstall the alternator, first the supplied alternator bracket (as
shown on the right in Figure 3a) must be installed. The bracket
bolts up to the same 2 holes the original A/C bracket bolted to
(see Figure 3b). Use the 2 supplied black M10x1.25 bolts. The
bolts can be tightened with an 8mm or 5/16” allen driver. Do not
fully tighten the M10 bolts until after the alternator has been
installed. This will aid in properly aligning the lower 2 holes in the
alternator with the threaded holes in the alternator bracket. Once
the alternator bracket has been bolted up, begin mounting the al-
ternator by inserting the supplied 100mm M8x1.25 bolt through
the upper alternator mounting hole. Use an 6mm allen wrench to
tighten this bolt. This bolt should thread into the block where the
top left mounting bolt for the A/C compressor originally went (as
shown in Figure 3c). The supplied tall black spacer should be fit-
ted between the alternator and the engine block as shown in Fig-
ure 3c. Thread the bolt fully in but do not tighten until the lower 2
bolts have also been installed.
Next, affix the lower 2 alternator mounting points to the alternator
bracket as shown in Figure 3d. Some applications May require
the use of the (2) supplied short, black spacers between the alter-
nator and bracket as shown in Figure 3e. There are two different
flange thicknesses on K-series alternator for the lower two mount-
ing bolts. If you have a 30mm (1.18in) flange, use the supplied
55mm M8x1.25 bolts. If you have a 40mm (1.57in) flange, use
the supplier 65mm M8x1.25 bolts. See the table below to see if
you should use them. DO NOT use the lower spacers if your applica-
tion does not require them.
