Other alternators produce other bearing setups. The back again bearing doesn't have as much load because the front (no belt tension around the back again) but nevertheless.... if you don't substitute it...... As they say inside the manuals, reverse process to re-assemble!

Alternator failure whilst driving will induce the battery gentle to illuminate to the dashboard. Before long after, all electrical elements will getting to shed energy, the automobile will stall, and leap-setting up won't be efficient.

Talking of newer stuff: Newer alternators have overrunning alternator pulleys on them. The alternator has the smallest pulley on the belt pushed extras, and it spins 4 or more instances as faster than every other issue pushed because of the belt.
