Need to replace the alternator bracket which is secured to the block on a 83 240D. The FO had an alternator installed which the mechanic cross threaded the bottom mounting bolt. Result is having to replace an alternator every year due to the front bearing wearing out. The angle of the alternator housing over time changes dramatically which binds the bearing. This is due to an oblong hole which develops over time in the bottom mounting hole because the cross threaded bolt.

Can the alternator mounting bracket be changed on the block without removing the harmonic balancer ?
