The damper pulley bolt tightening specifications, on a Caterpillar see 15 diesel engine, is 60 pounds per square inch. The pulley should not be tightened beyond 60 pounds.
on the Chrysler engine (420a) you do need a puller and installer to deal with the crankshaft dampener pulley.
AKA, crank pulley damper, crankshaft damper, torsional damper, or vibration damper.
Depending on engine displacement in general remove belt-s then bolt holding pulley to the crankshaft then using a puller remove the pulley, when installing use a installer not a hammer to put the pulley on the crankshaft.
The crankshaft position sensor is mounted on the front of the engine near the crankshaft pulley . Looking from the front it is to the left of the crankshaft pulley and is triggered by the teeth which are machined into the crankshaft damper (Chilton) You can see it from underneath the Explorer
Does the LSS have a 3.8L engine? If so, the crank sensor is behind the crank pulley/harmonic damper.
The crankshaft damper is behind the crankshaft pulley.
Depends on what type of vibration damper (crankshaft pulley) you have. Your local auto parts store probably has the one you need and can rent it to you.
The crankshaft pulley is the lowest pulley on the engine. Looking at the engine from the front which is looking at it from the passenger side fender the crank pulley is on the bottom of the engine and has a pulley with a pulley behind it with teeth on it.
You'll need to pull the passenger front wheel, remove the wheel well cover. This will expose the damper pulley on the crankshaft. Remove damper pulley, remove plastic engine cover. Look inside you will see the sensor. Be sure if you replace it to install the new one exactly the same as the old one was.
The crankshaft pulley is the large pulley on the lower passenger side of the engine.
Serious vibrations.
