2. PULLEy AND SPACER REPLACEMENT

A. Unplug the cam sensor connector. Remove

the five screws that retain the S/C mounting

plate.

B. 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 tensioner and replace with the

supplied 3" idler (4FU116-031) using the

factory hardware. (See Fig. 2-a.)

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 hardware. (See Fig.

2-b.)

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. 2-b.)

4. Secure the tensioner assembly to the

front of the engine. Use Figs. 2-a, 2-b as

guides for spacer placement.

NOTE: When a part is to be discarded, it should be

placed in an appropriate place so as to not be

confused with a similar part supplied in this

upgrade kit.

NOTE: Take care when removing so as to not lose the

0.097" spacer between the small idler plate and

the alternator.

NOTE: Leave the 3/8" screw and jam nut loose at this

time.

C. 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 .140" thick spacer

(2A017-882-01) using the factory hardware.

(See Fig. 2-a.)

D. 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.
