OIL DRAIN INSTALLATION
4.1 OIL DRAIN INSTALLATION
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 location. (See
Figs. 4-a or 4-b, depending on which side of
the engine the supercharger is mounted on).
It is best to punch the hole rather than drill.
D. Tap the hole with a 3/8"NPT tap approxi-
mately 1/4" deep. Pack the flutes of the tap
with heavy grease to hold the chips. Use a
small magnet to check for any stray chips.
*** NOTE ***
This method of rolling over the lip of the hole and
tapping works very well if carefully done and should
cause no problems.
E. Thoroughly clean the threaded area. Apply a
small amount of silicone sealer to the new
threads. Apply more sealer to the supplied
3/8"NPT x 1/2" barb, and secure in the pre-
viously threaded hole. Make sure a seal is
formed all around the fitting.
F. Drain the engine oil, install a new filter and
refill with fresh oil.
3/4" MAX. (PUNCH HOLE AS FAR FORWARD AS POSSIBLE)
*** NOTE ***
Removal of the oil pan may ease oil drain fitting
installation on some applications.
B. Remove any paint from around the hole
area.
C. Use a small center punch to perforate the
pan and expand the hole, switch to a larger
diameter punch and expand the hole further
to approximately Ø9/16". Most punches are
made from hexagon material and may be
placed in a socket with an extension to make
this procedure easier. Use caution so that the
hole is not enlarged too much and that the
punch does NOT contact the engine inter-
nals.
