"Notes: Bosch provides 2 different #s to replace this OE # on 900 models. Use AL 69 X (0 120 469 945) thru '87 ch#s H2008686, H3006971, & H7013654. Use AL 124 X (0 120 469 682) after '87 ch#s above and later models."
But there doesn't seem to be any way to specify whether you want the AL
69 X or the AL 124 X. They share the same SKU at all of the parts sites I've checked. The one I got says AL 69 X, and I have a 1990 900T. Is there any difference besides the label?Second question: How do you lock down the alternator's rotating assembly to get the 22mm nut off the shaft in order to remove the pulley/fan assembly? Sticking a screwdriver through the fan into the body might damage the blades, and I sure don't want to be sticking a screwdriver into the new alt to tighten the nut.
Thanks, Ludwig
