To fix the
Alternator pulley, start by spotting the decoupler pulley, the INA variety will take a different set of tools from the Litens version. To remove the INA decoupler, separate the negative
Battery Cable and take off the generator and accessory
Drive Belt. Encounter the decoupler with the help of Special Tool #8823 (VM.1048) which decides if the generator shaft has a hexagonal or splined shape. If the axle has a hex, slip on a 10MM deep socket; if it's splined, use either a 5/16" 6-point hex driver or a 10MM 12-point triple square driver. Use your hand to unthread the decoupler once the tool is brushed past clockwise. The decoupler should be mounted onto the generator shaft by hand using the Pulley tool; after that, insert Special Tool #8823 (VM 1048) and repeat the step to identify the kind of shaft. Tighten the nuts on the belt using a torque wrench in counter-clockwise motion, according to the specifications on the torque wrench, then replace the accessory drive belt and generator. With the Litens decoupler, unplug the negative battery cable, remove the belts and insert Special Tool #8433 on the hex end of the generator shaft. First, rotate the tool in a clockwise direction to break the decoupler apart, hold the decoupler outward by hand to unwind and later pass the decoupler pulley on the generator shaft and turn the tool anti-clockwise to tighten. After that, put back the accessory drive belt and generator, then link up the negative battery cable.
