7.3 6.0 & 6.4 PowerStroke Diesel Standard Pulley
This 8 Groove Pulley can be used on Ford PowerStroke Diesel alternators from
1994-up on the 1G, 2G, 3G, 4G and 6G series alternators requiring an 8 groove pulley.

For both F series and E series Ford Power Stroke Diesel

Dimensions 28mm Belt x 64mm Rib OD x 17mm Bore

Features CNC Machined Cut from Cold Rolled Steel

With a standard 7" Crank Pulley running at 650 RPM, the various sized pulleys will spin at:

That's an 18% Increase in speed over the largest stock pulley.

The Power Stroke Diesel with the 8 Groove Serpentine Pulley on the alternator was first used in 1994 with the Motorcraft 3G Series Large Case 130 amp Alternator. Ford used the 130 amp Large Case 3G series alternator until 1998. In 1999 Ford went to the 110 Amp Small Case 6G series Alternator for Power to Maintain the Batteries. Dual Alternators was an option, some years ran the 4G series with the Diesel when the vehicle was originally ordered but most people didn't get the Dual Alternator Option. The Small Case 110 amp 6G series alternator proved to be quite problematic for Ford, the small case alternator just doesn't have what it takes to Power Glow Plugs and Two Batteries.

CAUTION: Over Spinning your alternator can case alternator failure so be aware of your alternators RPM. Alternators are only good for about 18,000 RPM for short periods, for longer times running I wouldn't go over 15,000 RPM. To calculate an alternators RPM you take the Alternator pulley diameter and divide it into the crank pulley diameter. You do not count any other pulleys such as idler pulleys or power steering, just alternator divided into crank diameters. Example: Alternator Pulley Diameter = 2 inches / divided into 6 inch crank pulley equals 6/2 = 3, the ration is 3 to one, so if your motor is turning 1,000 RPM your alternator is turning 3,000 RPM's

6g alternator with collar — 6G Alternator With Collar

3g alternator without collar — Alternator Without Collar

The 8 groove Pulley cross section above shows the cutout at the rear of the Pulley that is required for 1999 and up 6G series Power Stroke Alternators that have an aluminum collar protruding out as part of the front housing casting. The earlier 3G series did not have this protruding collar so the rear of the pulley is not cut out. These pulleys with the cutout at the rear of the pulley can be used on the earlier 3G series well as the later 6G Alternator but earlier 3G pulleys cannot be used on later 6G series Alternators.

With the center hub cut out this pulley will fit both collared and non-collared front housings.

Alternator Pulley Removal and Replacement

The pulley on the 3G series and 6g series alternators do not have a keyway and do not use a locking compound to hold the pulley on. The pressure from the nut is what holds the pulley on and keeps it from slipping so great care should be taken to re-tighten the pulley. The nut may have a locking compound on the threads and may require slight heating to release the thread locker.

To remove the pulley you need a 1/2" drive impact wrench with a 15/16" or ??mm sockets for the impact wrench
The threads on these alternators are right hand threads, shaft is 17mm.
Hold the pulley with a rag or glove then using the correct socket size, impact the nut off, the pulley should then slide off.
Replacing is just the reverse making sure to tighten the pulley nut to the correct torque specs of 45 - 65 ft. lb.
