Adjustable Cam Gears
Note: These instructions help with a Timing Belt installation. Installing a pair of manually adjustable cam gears will allow you to fine tune the valve timing. When used properly, the fuel economy, torque, and horsepower curves can be manipulated to the driver's needs. Note: Expensive Equipment (a Chassis or Hub Dyno) is needed for proper tuning of adjustable cam gears after installation.
The Ford service manual says: 1. Unscrew the bolt four turns. 2. Position the tensioner so the locating tab is at approximately the 4 o'clock position. 3. Line up the hex key slot in the tensioner adjusting washer with the pointer that is located behind the pulley.Now you should be able to take off the belt (it should be loose). once the belt is off just let it hang. Take off the old cam gears, with a t-55 torx. Hold the camshafts with a set of vise-grips, as relying on the cam alignment tool can damage both the tool and the camshaft. Go easy on this so as not to strip to bolt, because it is really easy, I know! Now that the old ones are off, you can put the new ones one. Make sure they are at 0 degrees before you put them on, I am not sure if it matters, but it is better to be safe than sorry. It also doesn't matter in what position you put them on, but I would suggest putting them on, so that the marks are both facing the same direction. (Now, the cam tool is still in the slot the whole time!) Once they are on pretty tight, put the belt on. It should only be able to go on in one spot. Then once the belt is on, you need to tighten the tensioner.
1. Rotate the tensioner locating tab counterclockwise and insert the locating tab into the slot in the rear timing cover. 2. Position the hex key slot in the tensioner adjusting washer to the 4 o'clock position. 3. Tighten the attaching bolt enough to seat the tensioner firmly against the rear timing cover, but still allow the tensioner adjusting washer to be rotated using a 6mm hex key.This will ensure that the belt is tight. Now, once everything is back on, take out the cam tool, you may need to tap it out with a hammer. I would just crank the motor over a couple of times by hand, to make sure everything is turning ok. Then put the valve cover back on. You can leave the cam gear cover off. As to my knowledge, it doesn't hurt anything. Now put the spark plugs back in and connect the plug wires. Then put the cover back on that is under the car. Put the wheel back on are you are all set.
