2. OIL DRAIN

A. To provide an oil drain for the supercharger,

it is necessary to make a hole in the oil pan.

Locate and mark the hole per Fig. 2-a. The

drain hole must be punched rather than

drilled.

B. Remove the paint around the hole area.
C. Use a small center punch to perforate the

pan and expand hole. Switch to a larger

diameter punch and expand the hole fur-

ther to approximately 9/16" diameter. Most

punches are made from hexagon material

and may be placed in a socket with an ex-

tension to make this procedure easier.

D. Tap the hole with a 3/8" NPT tap approximately

1/4" deep. Pack the flutes of the tap with heavy

grease to hold chips. Use a small magnet to check

for any stray chips.

E. Thoroughly clean the threaded area. Apply a small

amount of silicone sealer to the new threads. Ap-

ply more sealer to the male portion of the 3/8"

NPT x 1/2" inverted flare fitting and secure in

hole. Make sure a seal is formed all around the

fitting.

F. Thread the tube nut and 1/2" x 90° aluminum

tube into the inverted flare fitting by hand. Do not

tighten until after the supercharger drain hose

has been connected. (See Figs. 2 b, 2 c.)

G. Drain the engine oil and change the filter.
H. Temporarily cap off the oil drain fitting to keep

out debris until drain hose is attached at a later

time.

I. Refill engine with 5W/30 synthetic or conventional

SH/CF rated motor oil.

NOTE: This method of rolling over the lip of

the hole and tapping it works very well

if carefully done and should cause no

problems.
