Items onto the upper stud of the starter solenoid were installed in the following order.
BMW bracket, part number: 61-13-7-671-355. The "flat" of the bracket should be parallel to the bake-lite tab (see photo).
Wire lug from battery.
Copper coloured wave washer.
Copper coloured nut.
The hole locating stud was fully screwed into the bracket.
The starter cover was temporarily installed making sure that both rubber grommets for the starter cover locating pins were installed in the engine case.
It was not necessary to fasten the starter cover in place with the screw (item 6), but it was important to have the hole where that screw installed, lined up. When that was done, I pressed down onto the started cover in an attempt to mark the inside of it by the point of the hole locating stud.
The starter cover was removed and inspected for a dimple left by the point of the hole locating stud. The hole locating pin was screwed out by a few turns and the process repeated until a dimple was noted on the inside of the starter cover.
