One of the side things still to be done is the alternator. There were no issues with the original alternator, but I thought that replacing the brushes and bearings would be a good idea.
At the same time, I will freshen up the cosmetics as per typical.
Here is the alternator sans pulley. Grime encrusted, but functional.
I followed the FSM and used a heat gun to warm up the back of the housing, and it separated without too much effort.
Once apart, I was able to assess the bearings and brushes:
Both bearings turned smoothly, but when spun quickly, there was some noise, so my conclusion is that they still had some life in them, but replacement makes sense.
The brushes are a lot less worn out then I expected. Now that I have gone this far, I will replace them anyway. That said, I bet this alternator had a lot of life left in it. Also, the slip rings looked basically perfect, no discernable wear grooves. Removing both bearings was easy enough with the normal tools.
The one tricky item was the four screws under the pulley that secure the front bearing. They are easy to muck up (Phillips head), but I managed. It is work the effort to get these screws out without damaging the plate they thread into, as that part does not seem to be separately available. However, it is a very simple part that you could make.
I elected to keep the regulator, stator and rectifier connected. However, this sub-assembly needs to come out in order to do the brushes. There are three screws that hold it all to the rear housing (and the nut on the rear connector). Two of the screws are directly accessible, but for the third, I had to shift the stator slightly to the side:
It's all apart now, and I have most of the parts on hand (new brushes, front bearing, screw sets etc.), but am still waiting on the small rear bearing.
Started cleaning up the housings. It is hard to get them really clean with gentle methods, so I am just going for reasonably clean:
The main thing this weekend was starting on the 911's valve spring replacement:
Did not get very far as I encountered a lot of "first time issues". Mainly around putting the valve keepers back in as the access is really tight (the compressor tool blocks some of the area, and the valve stem is deep down.
However, I have "developed" some techniques and acquired some helper tools so hopefully the rest of the job moves more quickly and smoothly.
I will continue to chip away on bugeye stuff part time before returning "full time" to it once the 911 is finished.
