Procedure
Issue A: 04/28/08 Page 25 of 48
(f) Place OE alternator bolt through supercharger
bracket and thread into alternator. Leave bolt
loose for now. (Fig. 14-5) NOTE: ONLY if
holes do not align, see *“Alignment
Procedure”.
(g) Thread in TRD M10 x 1.25 x 25 flange head
bolt into cylinder head. 14 mm wrench. Leave
bolt loose for now. (Fig. 14-6).
(h) Ensure supercharger drive tube assembly and
brackets are properly aligned or “seated”. Turn
the supercharger pulley by hand to confirm that
the rotation is smooth and does not bind or
exhibit any “tight” spots.
NOTE: If assembly does not turn smoothly,
then you have a misalignment issue that will
likely cause unit failure if it is not addressed.
See *“Alignment Procedure”.
(i) Proceed to uniformly tighten ALL supercharger
fasteners in the specified order at this time. First
snug, then torque fasteners in sequence
as
follows:
1. OEM Alternator Pivot Bolt: 16 ft-lbs
2. TRD M10 Flange Head Bolt: 16 ft-lbs
3. TRD S/C Rear Bracket Bolts: 47 ft-lbs
(NOTE: Split bushings installed in rear bracket
are meant to self adjust as the unit is secured to
the transmission. When tightening, observe that
the bushings slide freely in the bracket and
contact the transmission evenly. Do not force
bushing as damage to the bracket may occur.)
