C. OPTIONAL Belt tensioner assist up-grade:
1. Remove the three screws retaining the factory
spring tensioner to the front of the engine.
Remove the factory steel idler from the ten-
sioner and replace with the supplied 3" idler
(4FU116-031) using the factory hardware.
(See Fig. 6.1-C1.)
2. Locate the supplied tensioner assist plate.
Install the supplied 3/8-16 x 2.5" screw and
3/8-16 jam nut into the plate. Install the three
M8 x 55mm bolts w/washers through the plate.
Slide the three .75"OD x .328"ID x .927" long
spacers onto the previously installed hard-
ware. (See Fig. 6.1-C2.)
3. Install the plate, hardware and spacers onto
the factory spring tensioner. Slide the three
.75"OD x .328"ID x .140" spacers onto the
three bolts protruding through the tensioner.
(See Fig. 6.1-C2.)
4. Secure the tensioner assembly to the front of
the engine. Use Figs. 6.1-C1, 6.1-C2 as
guides for spacer placement.
D. Remove the factory idler pulley located just above
the spring tensioner location. Replace with the
supplied 3.5" idler (4FU016-021) and .875"OD x
.663"ID x .101" thick spacer (2A017-882-02) using
the factory hardware. (See Fig. 6.1-a.)
E. Replace the alternator pulley:
1. First remove the plastic cap from the end of
the alternator pulley to reveal the splined hub.
2. Rotate the pulley so that a round punch can
be inserted through the front of the alternator
into the alternator-cooling fan. This will hold
the alternator assembly from turning. Using
the appropriate splined hub tool (see notes on
page iv), loosen and remove the alternator
pulley. The threads are standard.
3. Install the supplied 8-rib alternator pulley
(4FU016-011) and secure using the M16 x
1.50" flanged nut provided.
