O. Finish routing the belt around the supercharg-

er and release the spring tensioner. The belt

may be very tight. In this case it may be nec-

essary to have one person retract the ten-

sioner and have another partially install the

belt on the supercharger pulley.

Using a 1/2" square drive (ratchet), retract the

plate mounted behind the spring tensioner

until the tensioner is about 2/3 of the way into

its travel. Holding it in this position, tighten

the center and pinch bolts and release the

tensioner plate.

*Q. Install the supplied 1/8"NPT x -4 x 90° fitting

from assembly 4GS130-026 to the oil feed fit-

ting on the supercharger.

*R. Secure the oil drain hose to the previously

installed brass fitting in the oil pan, making

sure to route in a smooth downward manner

and away from moving or hot objects.

*S. Attach the -4 oil feed hose to the -4 fitting

previously installed in the supercharger.

Secure away from moving or hot objects.

7. SUPERCHARGER INSTALLATION, cont’d.

* Applies to "engine oil-fed" unit only. V3

applications skip this step.

NOTE: Use only clean engine oil on the pipe

threads. Teflon tape or pipe sealant is not

recommended as it might loosen and cause

bloackage of the small oil feed orifice result-

ing in possible supercharger failure.

NOTE: Any dips, "uphill" sections, kinks or restric-

tions may cause drainage problems and

possible supercharger failure.

NOTE: The pilot hole from the tensioner may

require adjustment during belt fitment.
