  1. 25 Buick first start issues

    It may also be a weak spring and/or a brush that is not arced to match the commutator. Get a marker or pencil and cover the face of the brush, then spin the shaft a few times and look at the wear pattern on the brush.
  2. Getting the color right

    Upon further investigation, it looks like it's possible to get a wrinkle finish with standard spray enamel. There are lots of "recipes" for doing this (use your google-fu for details), but the gist of it is that it depends on the top and bottom of the paint layer drying at different rates. Heat seems to be a common ingredient: a heavy coat of paint, then put it in the oven for 20-30 minutes. Some folks call for spraying a layer of thinner (or lacquer), then painting over it; others call for laying down the color coat first, then spraying thinner on top of that. It's also been suggested that you can use commercially available wrinkle paint (e.g. VHT), then immediately spray it with the color coat. All seem to agree that whatever you do, you don't let the paint dry between coats, and you hit it with the heat while it's still wet. If you don't want to stink up the kitchen (which might seem to be a real risk), you should be able to make an oven of sorts with a cardboard box and a heat lamp or two (think Suzy Homemaker). As a practical matter, a production process would be as simple as they could make it. Baking the parts in an oven would be bad enough; would they use a two-coat process if they didn't have to? The key may be that they used a paint which isn't readily available today, as the older wrinkle paints supposedly incorporated tung oil to get the different drying rates across the paint layer.

    The ones he sends you might be just like the ones you have. Or maybe he installed new (weaker) springs as part of the rebuild. He did return all the parts he replaced, didn't he? Do you know the dimensions of the brushes? You may be able to make your own from carbon fiber rods at a fraction of the price. I believe it was posted on here earlier how to arc your brushes to match the commutator. If the issue is pressure, you might try stronger springs and/or a shim under the spring arm.

    Using the process I mentioned, it doesn't matter if the wrinkle paint is opaque; it's just there to provide texture. It is the top coat which is opaque, and that's what counts.

    If the top coat is opaque, it doesn't matter what color is under it.
  6. Getting the color right

    Random thoughts... - Red turns orange over the years. - It's entirely possible that different paints were used at different times during the production run. There's no reason to assume that an air cleaner painted in October was identical to one painted the following April. - Why not prime it, paint it with a light-color wrinkle finish, then cover with a top coat of the correct color? Wouldn't that end up with the correct texture and color?
  7. What came loose?

    That's probably the line to get in.

    Except that he's also ruled out the s/g and the battery.

    The gears can move when engaged with the flywheel; that's why they exist. That's not to say that you can turn the engine over by grabbing the starter gears, but they do need to move when engaged. Can you disable the engine so it doesn't fire, engage the starter gears, then turn the engine by hand? And if I may be picky, you said you inspected the flywheel gear; I must have missed it when you said you had inspected the starter and armature gears.

    Well, one might suggest that those two statements appear to be at odds. If everything mechanical was working perfectly, the gears would move when they were engaged. Perhaps more to the point, you continue to insist that 1) the starter works perfectly, and 2) there is no mechanical problem. Given that there seem to be few other possible explanations, one might politely suggest that there is a very good chance that one of those assertions is incorrect. Faith is all well and good in the proper place. In this case, knowledge is better.

    Again, the question was not concerning the flywheel; it was the teeth on the two starter gears. When you say they spin freely, that means when they are not engaged with any other gear, correct? So, the question remains: did you specifically inspect the teeth on those two gears? Might want to look at the armature gear while you're at it, just to be sure.
  12. 25 Buick first start issues

    How hot it gets would depend how long the starter is engaged, no? One would hope that it's not engaged long enough to get hot, as that would not be in the best interests of said starter. While it's true that one would expect both a voltage drop and increased current draw from a properly operating starter, we don't know anything about either the expected or actual current draw. I would agree that the reported voltage drop seems smaller than you'd expect -- which is one reason it might be advisable to to do a thorough evaluation of the starter. OTOH, the better the battery, the smaller the drop.
  13. 25 Buick first start issues

    But did you look specifically at the two starter gears? Remember how you said the starter jumped then stopped? One might think that one possibility is that it moved until the gears meshed, then a weak starter motor couldn't turn it any further -- but another possibility is that the gears meshed but couldn't turn because something's wedged between two teeth. You had the whole thing apart, no? It's not inconceivable that something dropped down into a gear then got wedged in the first time the gears tried to mesh. It might be worth spinning those gears and taking a careful look between all the teeth.
  14. 25 Buick first start issues

    Just out of curiosity, did you rotate the starter gears and take a good look at the teeth? If you've got something wedged between two teeth, that might well keep the gears from turning.

    Everyone says that because that's where's the evidence points. Be honest with yourself: that's where you'd be looking as well if you hadn't just paid $2500 to have it rebuilt. You keep saying it can't be bad, but emotion is a poor substitute for reason. Maybe it isn't bad -- but a stubborn refusal to even consider the possibility is doing you no favors. If you test it and it's good, you get to eliminate one possibility and say "I told you so." If you test it and it's bad, you fix your problem. Either way, you win.
