Let's go to the ETK section
Engine electrical equipment
I'll start with the units on the generator.
Alternator mounting parts


Part #1 - support bracket (32 41 1 264 642).
Part #2 - bolt M8X30 (07 11 9 913 664) - 2 pcs.

The generator support bracket is also a bracket for the power steering pump. Although, there is also a separate bracket - only for the generator. This is exactly the bracket I had installed earlier, but I replaced it when installing the hydraulic booster. Therefore, I will immediately write here about the fastening of the power steering pump.
Power steering pump. support bracket


In the photo, there was a strange reflection on the plates - as if they were rusty) In fact, they are shiny and beautiful)

So, we assemble the bracket for the generator and the pump. Plates #8 and #9 will be installed later, together with the pump.

We fasten the bracket to the engine block with two bolts from the side and one bolt from the front end.


Next, about the details of the generator.
V-belt


Part #1 - V-belt 9.5X965 (11 51 1 706 710). I bought all the belts from the manufacturer Continental. AVX10X960 generator belt.

Part #2 - insulating part 8/5MM (12 31 1 286 664) - 1 pc. Plastic cover on the terminals of the generator. Plastic washers for generator terminals and nuts with washers for wiring terminals are not specified in ETK.
Part No. 3 - BOSCH generator capacitor (12 31 1 356 564) - 1 pc. According to the Bosch number (0290800036), it is much cheaper.

Part No. 4 - elastic washer B6 (07 11 9 932 099) - 1 pc.
Part No. 5 - bolt M6X8 (07 11 9 913 420) - 1 pc.
Part No. 6 - generator ground wire L=170MM (12 52 1 312 124) - 1 pc. In the original, it is red for some reason - strange. I made it myself from a brown wire, like all "ground" wires in BMW.

I had no complaints about the operation of the generator, but it did not look very beautiful, so of course I also completely disassembled and restored it. Replaced both bearings, brushes, contact rings of brushes, rubber sealing ring, rubber bushings, capacitor. Everything else is cleaned, painted and galvanized.

Several types of generators were installed on the E30. In my case, it is an 80A generator - Bosch Type N 0 120 469 619.

Part No. 23 - generator "brushes" (12 31 1 727 756) - 1 pc. Set of "brushes" Bosch (1127014022).

Part No. 24 - rotor repair kit (12 31 1 727 762).
We install rubber bushings in the front cover and metal guides, fix them with washers and a retaining ring. If you look carefully at the ETK scheme, the upper and lower guides are installed from different sides. This is not accidental, and it is important! Previously, I did not pay attention to this and put bushings on one side. At the same time, the generator becomes a little oblique, and probably that is why the upper rubber sleeve was constantly wearing out and the belt began to squeak. The bushings protrude at different distances and this compensates for the difference in the plane of the lower attachment and the tension bar. In later generators, these bushings were completely removed, and different protrusions were simply made on the front cover from above and below.

Install the rubber ring in the generator housing.

We fasten the diode panel with the winding with six screws.

We install the capacitor and terminals.

We insert the rotor with bearings, screw the front cover, pulley and impeller.
Finished result:
Generator


Part #1 - generator (12 31 1 288 409).
Now the generator has a much better look and condition.




Here, the difference in the size of the protrusion of the upper and lower bushings is clearly visible:

We install the lower bracket on the bracket, and the upper - on the tension bar. The tension bar is screwed to the cover pin.



The generator is installed. I will install and tighten the belt after installing all the pulleys.
