10. SUPERCHARGER INSTALLATION, cont’d.

F. Install into the supercharger gear case the supplied

Ø5/16 x 1.25” alignment dowels. (Slight heating of

the gear case may be necessary to make the instal-

lation of the dowel pins easier.)

G. Align the four hole pattern on the mounting bracket

making sure that the larger diameter holes are

aligned with the alignment dowels. (See Fig. 10-b.)

Tap the mounting plate so that the mounting plate

is flush with the gear case and the alignment dowels

are running through the plate.

H. Align the counter bores in the black coupler hous-

ing with the alignment dowels passing through the

mounting plate. Lightly tap the housing until it is

flush with the mounting bracket (

See Fig. 10-c.)

Loosely insert the three 12mm bolts through the

washers and the mounting plate into the super-

charger. Do not tighten. (

See Fig. 10-c.)

J. Apply a thin layer of grease on the inside diameter

of the steel supercharger drive coupling containing

three Ø1/4” dowel pins. Install the supplied key and

drive coupling onto the supercharger input shaft.

Heat may also be necessary to install the coupling

onto the shaft. (A propane torch will make this easier

if needed.) Verify the coupling is bottomed out on

the shaft. Secure the coupling with the supplied

Ø1.0” washer and 3/8-24 x .75” HXHD screw. Use a

light thread-lock compound. (

See Fig. 10-c.)

K. Install the supplied composite ring onto the three-

pin coupler located on the supercharger input shaft.

(

See Fig. 10-d.)

L. Lower the supercharger and mounting plate into

the engine compartment. Align the four lower

holes in the mounting plate with the four holes in

the transmission bell housing while aligning the

six-hole composite ring on the supercharger with

the three-pin coupling on the installed drive shaft

assembly. Connect them together. Verify that each

set of pins is inserted into the raised bosses on their

corresponding side of the composite ring. Align the

holes so that one side of the pins alternate with

the opposite side of pins. Slide the two assemblies

together until a positive stop is felt and the couplers

are flush with the composite drive coupling ring.

(

See Fig. 10-e, 10-f.)

M. With the mounting plate positioned on the transmis-

sion, install each of the three supplied 8mm bolts

through a washer, the mounting plate and a spacer.

Note the spacer thickness. The two .85” spacers go

on the front two bolts while the two .70” spacers

go on the rear bolt and stud. (The spacers must be

installed between the bellhousing and the mount-

ing plate.) Do not tighten.

N. Loosely install the supplied 8mm nut and washer

onto the stud.

O. Align the black anodized coupler housings and se-
