J 23600-B Belt Tension Gauge
1. Run the engine, with no accessories on, until the engine is warmed up. Shut the engine off and read the belt tension using the J23600-B placed
halfway between the generator and the power steering pump. Note the reading and remove the J 23600-B.
2. Start the engine with the accessories off and allow the system to stabilize for 15 seconds. Turn the engine off. Using a 15 mm socket, apply
clockwise force (tighten) to the tensioner pulley bolt. Release the force and immediately take a tension reading without disturbing belt tensioner
position.
3. Using the same wrench, apply a counterclockwise force to the tensioner pulley bolt and raise the pulley to eliminate all tension. Slowly lower the
pulley to the belt and take a tensioner reading without disturbing the belt tensioner position.
4. Average the three readings. If the average of the three readings is not between 133 - 222 N (30 - 50 lbs.) and the bolt is within the tensioners
operating range, replace the tensioner.
