Make sure you have received the following:

1) Generator Pulley
2) Crank Pulley
3) Belt Adjusters Assembly
4) Two 8mm Studs
5) Napa Serpentine Belt

Before starting, for safety, remove battery cable. Next remove the generator pulley nut and washer. Remove pulley half, then remove belt. Remove pulley half from generator using a gear puller if you have to. Next remove the crank pulley bolt and washer. Use gear puller to pull the crank pulley off. At this time, remove the two nuts holding the fuel pump on, remove fuel pump. Remove the nearest two nuts from the generator stand. Remove the two studs.

Now you are ready to install your BMD pulley system. Be sure all areas are clean so pulley system will fit properly. Install the two 8mm studs at the base of the generator stand. Disassemble the Base from the Slider of the Belt Adjuster Assembly. Mount the Base over the two studs you just installed. Replace washer and nuts and tighten. You can now reinstall the fuel pump. Install the new crank pulley. If pulley does not go on by hand, you may use a rubber mallet or something soft that will not damage the pulley. Replace pulley washer and bolt (tighten to 33ft. lbs). Now install the new generator pulley. Install with flat face of pulley toward the generator. (Note: on some Bosch alternators there is a casting nub that has to be removed or the alternator pulley will rub.) Replace nut (tighten to 33ft lbs). Reassemble the Slider to the Base, but leave button head bolt loose. Next install the belt. The roller on the Slider goes on the outside of the belt. Slide the Slider adjuster to the right to tighten the belt. There should be about 3/8" play when belt is right. Reconnect the battery and you are all set to go.

For Sand Seal applications, 1/8" spacers and seal are needed. Installation is the same except when pulleys are off, install spacers and insert the seal into the case.
