46-710 in the w115 cd manual. really simple. not
with a friend took off a broken bracket and replaced it once. terrible job. most difficult. the bracket has broken again. its his car now, was mine, but if i was going to fix it again i would support the subframe, undo the four subframe bolts and raise the front of the car up. i think both the bracket and pump would be accessable then. we didnt take the pump out, just changed the bracket. took off the fan, removed the battery and its pan.

since the bracket has broken again i would switch the old style p/s pump and
bracket to the newer style, put the battery at the passenger fire wall if there is no a/c or in the trunk.

good luck
