*DIY* NST Idler pulley upgrade. FG2

MADDOGSI · 03-29-2007, 01:24 AM

OK boys and girls here is the latest from the guys at NST and some cooperation from myself for the FG2.This is the new Idler pulley to go with the crank and Alt to be able to keep the stock belt.

First and very needed to do this is a serpentine belt tool.this is needed to give the clearance between the tool and the pulley during the install of the new idler pulley.

Next remove the belt.With a 14mm socket, loosen and remove the idler pulley.

Now for the new pulley.See the size difference from stock to NST.

Next with the belt in place, position the NST pulley with the belt over it so it can be installed back in place as shown.you will need to move the tensioner and install the pulley/belt together.there is not enough room between the engine mount and pulley to put the belt on after the idler pulley is in place.Install the pulley over the stub shaft.Install the bolt and torque the bolt to 28 ftlbs +/- 2 ftlb.DO NOT reuse the black washer it will not fit this pulley and is not needed.

after that it should look like this.Now dont worry about the clearance. there is a 2mm gap between the mount and pulley.since these are two stationary points the gap will never change.but the belt is 3mm thick, which just doesn't quite squeeze in.

If a guy wanted too he could grind and polish a bit off the mount to be able to take the belt off with pulley still on and for a bit more clearance,but again there is no need too.after that you have one sexy looking pulley set and that uses the stock belt.so no need to try to go and find a shorter belt now.

Looks nice, the clearance isn't as bad as it looks is it? Looks a tad tight in there.
