1965 Mercury Comet - Serpentine Solution

All fasteners for the new serpentine drive equipment are Allen head. Here, the new main drive pulley goes into place using a large Allen wrench to drive the fastener home.

The next part to be added is the water pump pulley, shown here being attached to the pump flange. The fasteners have a rounded and polished head for a finished appearance.

To begin the tensioner attachment, this billet aluminum plate is fit with three bolts. Two are 31/48 inch and the third is 71/416 inch.

Next, three spacers of equal length are placed over the bolts, and the whole assembly is installed onto the front of the passenger (right) side cylinder head. The Allen-headed bolts recede into the countersunk holes, leaving a flat surface on which to mount the tensioner assembly. Use antiseize compound on any bolts going into aluminum here.

Two Allen-headed cap screws go through the tensioner base and attach it to the billet plate. Here, the cap screws are tightened up using an Allen wrench.

Turning our attention to the other side of the engine, we begin the alternator installation in the same way. A billet mounting platform is created using spacers and Allen-headed cap screws.

Three bolts run through the alternator's mounting bracket. Two go through the billet spacer and into the cylinder head, and the third is used to attach and support the alternator between the bracket and cylinder head.

Before our Powermaster alternator can be mounted into position, we want to change over to the machined alternator fan provided by Concept One. Using a socket, the alternator pulley's retaining nut is removed.

The Concept One alternator fan is installed along with its aluminum pulley. Using the original nut, the fan is secured. Later, a billet aluminum plug will adorn the alternator pulley face.

With the prepared alternator held in position, the third alternator bracket bolt is installed into position.

Since adjustment at the alternator is no longer necessary, the unit is hard-mounted in an unmovable position. Belt tension is regulated automatically at the tensioner pulley.

This comprehensive instruction sheet will guide you through the whole installation process. Here, we refer to it for the correct routing of the serpentine belt.

The belt is easy to install. Just lay it into the grooves on each pulley according to the diagram in the instructions, and using a socket or wrench, collapse the tensioner pulley arm enough to allow the belt to fit over the tensioner pulley and then release the tension.

As a finishing touch, the billet end cap is added to our alternator's pulley face. Our new Concept One serpentine front dress is a cool and smooth running setup that looks great on the front of our Windsor engine. The single-belt system is a great upgrade for cars with multiple drivebelts, allowing simple belt changes, or, as mentioned earlier, if you're installing a fresh late-model engine without any front accessories, the Concept One system is a perfect way to get everything you need.
