Tom,
The clamp that you mention is used on my 1962 Carrera 2 to seperate the oil lines to the front coolers they'er used in several places on all 356 Carrera's
with front coolers.

Rolly

I should always try to remember that the apple never falls far from the tree when it comes to parts used by Porsche for race applications.
It makes perfect sense that the part was already on the shelf from having been specified for use on another model Porsche, in this case the Carrera 2 with front coolers.
A PM received from a fellow board member on the same subject relates the following information:
"I am working on a 57 Carrera coupe right now and am very familliar with all the parts used to build one. The clamp / bracket you detail is a bigger version of the DIN 72572 used on 356's in two places, one of them being up front to hold the two fuel lines coming from the Autopulse electric pumps.
I am pretty sure this DIN spec part is what the factory used in a larger version to hold down the lines you show. In the 356's it was zinc phosphate plated."
If someone has a parts list handy for Carrera 2, perhaps they would be so kind as to post the hardware part identification number. Perhaps something like: DIN 72xxx.
Thanks for solving this mystery regarding the origins of the clamp.
Regards,
Tom
Tom,
My original C2 parts book lists the brackets as 692.107.357.00 this would mean that they were a specific Carrera part and not just a standard DIN spec part. As I e-mailed you a simmilar bracket (though with a smaller diameter) is used on Carrera's fitted with autopuse fuel pumps, the 356A parts books lists this bracket as 12 DIN 72572. The 12 denotes the diameter of the lines which can be clamped down.
Hope this helps,
JK
Bert, Gib, OliveR and others were quick to ask about the cooler installation when this thread first started. More than a year later, we are finally getting to that stage of the project.
A close-up view of the top-mounted hard lines on the left hand, fender mounted oil cooler appears below as an attachment to this post.
A soft line joins the outboard, top-mounted hard line to the cross over line in the fuel bay.
The inboard, top-mounted hard line threads directly to its respective cross over line.
A fellow board member fabricated the rock shield for the LH cooler in alu. We finished the shield in satin black paint.
Note that the cowl vent cavity has been blacked out by hand brushing it with satin black.
Liberal amounts of tweaking, fiddling and finger massage go a long way towards getting things to line up.
Please take a look:
JK: Thank you for sharing the 692.107.357.00 part number for the Carrera 2 bracket/clamp!
Tom...looking great! Was that soft line hard to find?
John
Hello John,
Thanks for the thumbs up.
Finding soft lines proved to be challenging and for a while the prospect of completing the project to factory specifications did not look promising. They are really hard to find. My guess is that the 914-6 GT guys bought them all up years ago...
The soft line on the hot rod is a reproduction piece. If you have some OEM spares, please PM!
A friend in Germany found a shop willling to make up the NLA fittings and then another shop assembled the lines to OEM specs. A prior post (#259) provides additional details relating to the supposed origins of the hardware for the OEM soft lines.
While we are on this topic, it may be interesting for readers to note that for the 2,247cc engines (66mm x 85 mm) making 230 DIN bhp at 7,800 rpm the Werks did not find it necessary to fit an additional oil cooler. These engines used a case mounted cooler and the standard 911 S oil cooler in the RH wing, the later being standard fitment beginning with the B Series S.
For the 2,380cc engine (66mm x 87.5mm) producing 250 DIN bhp the standard crankcase mounted cooler was replaced by a second front wing mounted cooler on the LH side, as shown in the image attached to this post.
Both the 2,247cc and 2,380cc engines used Biral cylinders (cast iron cylinder with bonded ally fins).
With the advent of the 275 DIN bhp 2,5L engines, 2492mm (70.4mm x 86.7mm) with Biral cylinders and 2466cc (66mm x 89.0mm) with Nikasil cylinders, the Werks continued to fit the second front wing mounted cooler on the LH side.
Please refer first to the TYPE INDEX OF THE COMPETITION ENGINES attached to this post and next the specfications shown in the "Oil Cooler" at the bottom of the second spec sheet for TECHNICAL DATA of the COMPETITION ENGINE 911S + 914/6 under those columns relating to engine types 911/21 and 911/70. Wheel case-right and wheel case left is how the factory refers to the cooler locations, and note that no cooler is specified for mounting on the the engine case location (as shown for 901/25 and 901/26, both of which are 914-6 power units).
Stateside we refer to this set-up as a "bi-lateral" oil cooler system. Just the ticket for a hot rod.
Thanks Tom...that's why I asked, it looks just like one of mine. I was hoping you had found 20 or 30 of them hidden away. I could use a spare also.
If I find some I'll let you know.
Your car's looking great.:)
John
Raj ( how are you ) re this quote are you talking about the yellow #80 car run at le mans or the yellow #64 car (yellow with blue graphics ) ? i was to believe, based on the photos of the yellow le mans car, that this car was a 72 year model?Quote:

Lovely workmanship and attention to detail as always Tom ;)
Thanks for the update & Seasons Greetings!

Modifications to the the stock '71 dry sump tank included adding capacity and baffling for better oil control. Here it sits awaiting installation.
The filler neck will be modified to accomodate a larger, 80mm Blau filler cap as well as a welded-on, threaded fitting to accept the Preschona pressure relief valve. This will duplicate the look of the 1971 Safari ST filler necks.
The pressure relief valve has been cleaned and detailed. The body of the Preschona valve is an aluminum casting and although it looks heavy, in fact it weighs very little.
All the hard and soft lines required to complete the installation of the bi-lateral Behr oil coolers and the pressure relief are on hand.
Next, we'll take a look at preparing the wiring loom for a Bosch cut off switch to be mounted as per Race Department practice on the speaker grill. See switch in the last image.
