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. Apply 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.

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.

2. OIL DRAIN (ENGINE OIL-FED APPLICATIONS ONLY. APPLICATIONS WITH V-3

SUPERCHARGERS SKIP AHEAD TO STEP 4)

A. To provide an oil drain for the super-

charger, it is necessary to make a hole

in the oil pan. Locate and mark hole per

diagram. The drain hole must be punched

rather than drilled. (See Fig. 2-a.)

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

further to approximately 9/16” diameter.

Most punches are made from hexagon

material and may be placed in a socket

with an extension to make this procedure

easier.
