OIL FEED

A. The supercharger uses engine oil for

lubrication and must have an oil feed
line connected to a filtered oil access
on the engine.

B. Remove the 1/4” NPT plug located on

the engine block just above the oil
filter boss. Replace the plug with the
supplied 1/4” NPT x 1.5” nipple, 1/4”
NPTF x 90

elbow and 1/4” NPT x -4

flare fitting (see

Fig. 3-a

C. Connect the supplied feed line to the

flare fitting (make sure that the silver
fire sleeve has been slid onto the feed
line to protect from radiant exhaust
heat) and make a gentle downward
loop around and back up to the rear of
the engine (see

Fig. 3-a

). Secure the

hose with the tie wraps provided,
routing it away from exhaust heat,
chaffing and/or sharp objects. Tem-
porarily cover the open end from de-
bris until the connection is made to
the supercharger in step 5.

OIL

FILTER

TO SUPERCHARGER

OIL DRAIN, cont'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.

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 45

elbow and secure in hole. Make sure a

seal is formed all around the fitting. Install the supplied 3/8" NPT
x 1/2" barb fitting. Rotate the fitting assembly so that the oil drain
hose (installed in step 5) can be easily routed to it.

G. Drain the engine oil, install a new filter and refill with fresh oil.
H. Reattach anti-roll bar and crank trigger connector.

NOTE: This method of rolling over the lip of the hole

and tapping works very well if carefully done
and should cause no problems.

NOTE: Use clean engine oil

on the pipe threads.
Teflon tape and seal-
ant is not recom-
mended, as it might
loosen and cause
blockage of the small
oil feed orifice result-
ing in supercharger
failure.
