Tips & Tricks
Checking Pulley Alignment
The belt needs to be removed to do this. You will need a straight edge and ruler to measure. First draw a diagram of circles, one representing each pulley. The straight edge will be kept on the face of the crank pulley for all measurements. Remove the belt and place the straight edge across the crank pulley. Measure from the straight edge to the first peak on the crank pulley. Write the measurement in the circle representing the crank . Keep the straight edge on the crank pulley and reposition it so you can measure to the first peak of each of the other pulleys with ribs. Write each measurement in its circle on your drawing. Comparing the measurements will tell you if anything is misaligned and by how much.
Balancer Face to Water Pump Flange Measurement
The water pump, water pump housing and crank shaft dampener must be installed for this measurement. The crank and water pump pulleys must be removed. Place a straight edge on the water pump puley flange (surface that the pulley touches) and allow the straight edge to drop down in front of the crank shaft dampener. Measurement from the straight edge to the front face of the dampener (surface that the pulley touches).
