How to Measure a V Belt Length

V-belts have a cross section resembling a "V." The narrow end of the "V" taper sits inside the groove of a taper wheel. This increases the contact area between the pulley and the belt. During use the belt stretches and will eventually break. Installing a correctly sized replacement belt between the pulleys will ensure the belt sits under proper tension. A simple method for determining the length of a V-belt exists that allows you to avoid using a complex mathematical formula.

Instructions

Wipe the inside groove of the pulleys clean with a rag.

Pull a length of 1/8-inch diameter twine around the two pulleys to be connected by the V-belt. Pull the twine tight. Ensure the ends of the twine overlap by 4 inches.

Draw a line across the overlapped twine with a permanent marker. Make sure the line is visible on both pieces of twine. Remove the twine from the pulleys.

Set the marked twine flat on a firm surface. Hold one end of the twine on the end of a tape measure. Pull the twine taught while it sits next to the tape measure. Read the dimension where the second mark on the twine falls on the tape measure to determine the length of the V-belt.

How to Turn the Distributor on a 1985 Camaro 2 8 With a V 6 Engine

The distributor on the 1985 Chevrolet Camaro is the main component that the spark plugs receive their voltage from. The distributor also supplies the proper firing order to the spark plugs to keep the engine in time. The gears on the bottom of the distributor shaft are turned by the camshaft. As the camshaft turns the distributor shaft, the distributor shaft turns the rotor inside of the distributor cap. The rotor then turns inside of the distributor cap and supplies the spark plugs with the proper amount of voltage to keep the engine timed.

Instructions

Park the 1985 Chevrolet Camaro in a safe working area and open the hood. Shut the motor off and engage the parking brake.

Raise the hood and prop it in place. Locate the distributor cap near the back of the engine. All of the spark plug wires are attached to the top of the distributor cap.

Mark a straight line on the front side of the distributor cap with a marker. Also mark another straight line on the front side of the distributor cap base directly below the other line. This will help you remember the exact setting of the distributor before moving it.

Loosen the hold-down screws on the bottom side of the distributor with a Phillips-head screwdriver.

Grab the distributor with both hands and turn it clockwise to retract the timing. Turn the distributor counterclockwise to advance the timing. Be sure to make short turns when turning the distributor. Once the distributor is timed to your liking, screw the hold-down screws back down tight with the Phillips-head screwdriver.
