My 1974 Carrera

[IROC]

Those brake lines are still available from Porsche. Ask me how I know.

It’s an OK/good Machine, but it’s very particular about the media that you use.
If you simply run the various baking soda, powders available at Harbor freight, the result is not that good.

Ok thanks for the info. Could you share the vin for your car? I keep track of all the 74/75 carreras and I would be I don't have yours on the list since it was with your friends family for so long.

Yeah, but I have the materials, tooling, and need to stay in practice.

While pondering exactly how I’m going to build/modify/configure this 2.7 L engine, I figured I would clear my mind by removing the calipers and rotors at each of the four corners.
That’s when I noticed that the rear wheel bearings were shot.
Also, the rear arms needed some cleaning up.
And, in true mission creep fashion, if you’re going to redo the rear wheel bearings, you might as well redo the rear parking, brake mechanism.
Decided to replace it he OEM rubber bushings with Elephant Racing parts.

Moving onto the cylinder heads, I had a lower valve spring seat that was stuck to the cylinder head. I tried letting it soak in some penetrating oil, but that didn’t work.
Since it had to go into the Bridgeport to mill off the valve guide ends, I chose a larger bit, and simply ran it at a very low speed until the seat was freed.

[11BC2]

Slightly more mission creep but what are you gonna do?
When I had removed the fuel tank, I noticed near the battery area, some of the stone guard material was missing, and there was a light to moderate rust.
So I took a few wire wheels to the fuel tank area, and remove the old stone material, applied self etching primer, and then reapplied new stone guard material

Great job! Looks like you got lucky not having rust under the battery tray from vapor and a leaky battery. My '74 was not so lucky, lots of replacement parts. I went with a LION battery to save the metal and at least 30 lbs. Have fun!

Well, since I’m here…

While up on the scissor lift, I noticed that both horn trumpets were broken/missing. Plus, there was still one of those ice cream truck looking megaphones from the antitheft system that I needed to remove.
Removing the front bumper was easy enough, as were the fenders, except for a small tack weld at the very top rear section of each fender.

After removing the fenders, I noticed there was some light rusting on the chassis, so I wire wheeled the old Stone Garden material off in order to assess the damage.


As you can see, the damage wasn’t nearly as bad as I’ve seen on cars of this vintage, particularly from outside of California.



I chose to only remove the material following the wheel arch down to the lower rocker area, and after shooting a coat of self etching primer onto the bare steel, I applied a thick coat of new stone guard material

Back to doing some engine work.
The rocker arm shafts looked like they needed some polishing to determine if they were usable. At first, I thought they might have had some light rust on them, but it turned out. It was just oil staining.
Chucked them up in the lat, and simply use the Scotch-Brite pad.



After cleaning, I checked the diameters and various places and went with the lowest number.

When you reinstall them, rotate the shafts 180 degrees, so that you put the unworn part of the shaft into the wear zone.

We tumble the shafts to polish them in a corn cob media with rouge imbedded... come out beautiful, no measurable diameter change.

Cheers

yes, in another 1/2 century you will need new ones

[11BC2]

I took the engine tin, transmission/entry mounts and brackets and miscellaneous small parts to my local powder coating outfit

That is an excellent idea, seeing that I reload rifle ammunition.

Great story! I almost sold my 74 and even tried BAT but am so glad it never made it past my driveway. It's an early 74 (#0039) that I'm finding is even more rare within an already limited number production run (USA Carrera's). And incredibly well preserved and original- making it even more of a find. What is your chassis #?

I’m glad you did not sell it.
It is funny to me how people kind of look down on the US market Carreras that were made for 1974.
Off of memory, there was like 530 made.
The VIN is: 911 44 0109

[MY911S]

Ah nice that might be an early one too. Do you have the tunnel reinforcement and the 73 RS flares? Only the early cars in 1974 had them as I understand.

[MY911S]

Took another look at your interior pic. I didn't see the tunnel reinforcement plate. This thread shows what it's like inside and under the car https://forums.pelicanparts.com/porsche-911-technical-forum/1083091-tunnel-reinforcement-late-73-2-4t.html

My car was built September 1973, which is after August vacation. So I assume it does not have it.
