67 Bypass Hose/Fitting Paint SB

Re: 67 Bypass Hose/Fitting Paint SB

What is the deduction for a bypass hose, fitting and clamps that is not painted orange on a 327 350 HP 67? (or any 63-67 for that matter)

Mike,

The 63/4 JG captures "engine paint" as a separate line item with 20 originality and 20 condition points. I suspect the JG for all other years are consistent with this. Overspray for all bolt on components roll up into this line item, so it's a krap shoot as to how any given mechanical judge will break out and score a bypass fitting and hose.

Although paint overspray could be considered "finish", it should not be individually judged again on the remaining lines on the score sheet. That would be a double dip and unfair to the owners.

Tracy,

You have an interesting point. I'm not sure how I would judge these items now.

Michael,

Here's another. This is from a shot of the 66 chassis line at St louis. A 350 HP being installed in the chassis. I'm sure many of you have seen the full size picture. The bypass hose is definitely coated in orange.

Michael,

The picture you referenced (originally in post #25 above, gone now) is also in Adams, p. 359.

It was my previous understanding that the lower alternator bracket was loosely attached at Flint through the lower bracket bolt-hole into the lower boss at the front of the LH exhaust manifold, and the bolt and bracket were both painted orange with the engine. This appears to be confirmed by the 1966 AIM (UPC 6-A2) and the 1967 AIM (also UPC 6-A2), showing a pre-existing bolt with a note saying "Loosen Bolt Prior to Installing Alternator & Re-Torque to 25-35 LBS. FT."

But how can that be? By 1966-67, the exhaust manifolds were NOT installed before engine paint, so there would have been no LH exhaust manifold for the alternator bracket to be bolted to. The other (inboard) end of the lower alternator bracket looks like it attached to the upper LH water pump bolt, called out in the AIM (6-A2, item 8) and installed at St. Louis, not at Flint.

In the St. Louis assembly line photo (Adams p. 359), the lower alternator bracket looks like it's painted engine orange, but the bolt head (bolt through the bracket into the LH exhaust manifold boss) looks un-painted. So how was the alternator bracket painted orange if it wasn't attached to the engine (at either end) when the engine was painted? Was it painted orange while separate from the engine, and then installed with an unpainted bolt at Flint, after the exhaust manifolds were installed?

Do you know what the story is here?

Scott,

There seems to be only one logical sequence of assembly, and it's not especially logical.

The engine assembly,including alternator bracket attached to water pump, minus exhaust manifolds, is painted orange. The attaching bolt is also painted orange.

The exhaust manifolds are installed and the lower alternator bracket is bolted to the manifold. The engine is shipped to St Louis.

At St Louis, the alternator bracket bolt at the water pump is removed and pitched. A new bolt and alternator adjusting brace are installed with the new unpainted bolt.

The bracket bolt at the manifold is loosened and the alternator is installed. It is loosened because the hole in the bracket has to be aligned with the threaded hole in the manifold. It is retorqued.

Why it was done this way, I do not know. It makes no sense but that's the way it was. I don't understand why the bracket wasn't installed at St Louis instead of Flint.

Re: 67 Bypass Hose/Fitting Paint SB

Thanks Michael.

Very interesting, I will paint my engine with same sequence when the time comes.

Do you know what bolt (size, grade, indented or regular hex, and typical headmarks - finish looks plain in photo?) Flint commonly installed at this location after engine paint, when they attached the outboard end of the lower alternator bracket to the LH exhaust manifold, on an L79 for '67 model year? I don't know what to look for in my "mystery bolts" bag, if I even have the original bolt for that location.

Scott,

Sorry, I don't remember the bolt info. I probably knew years ago but not now. (I'm old now) Hopefully, someone here will have that info.

Re: 67 Bypass Hose/Fitting Paint SB

Noting the initial conversation between these two veterans about original orange, I offer you this now 47 year old example of original orange. One thing you should note is inside the orange where the hose clamp slot was how this showns us exactly how the hose clamp was put on at Tonawanda to this 427 engine, by the presence or lack of - orange paint. Now what is it that isn't shown in this picture66 427 bphose clamp c.jpg
