Jeep 53020689AB Crankshaft Damper

Remove the cable far from the negative terminal of the battery. Disassembly process involves the following: Erase the system cooling fans and also the shroud. Remove the drivebelts and rotate the belt tensioner in the opposite direction to the crankshaft pulley. Coil the strap wrench or chain wrench around the crankshaft pulley and while pulling it with your hand, place a breaker bar and socket on the crankshaft pulley center bolt and turn it counterclockwise until it's loose. For this, there are specific holes provided in the crankshaft and pulley and using a puller use the jaws of the puller in such a way that they grip the hub of the pulley only and not the outer ring, at the same time check that the puller screw does not go into the threads present in the nose of the crankshaft. Examine the oil seal riding surface on the pulley hub; if the surface has been grooved out, an oil seal sleeve may be available which will fit on to the hub and renew the sealing surface and this can be fitted with a hammer and a block of wood. Coat the portion of the hub of the pulley with clean engine oil, ensure that the groove in the pulley is properly engaged with the key on the crankshaft, insert the crankshaft pulley over the crank shaft as far as it may go to be followed by the use of a vibration damper installation tool in forcing it the rest of the way. Replace the crankshaft pulley retaining bolt and tighten it to the recommend torque. The rest of the installation is done in the reverse sequence of what was followed to remove it.
