906-127
May 22, 2004
Still
making some glass parts. This is the inside brace for the
front cooler cover.
The part
will be a two lay-up system. Because of the nooks and crannies,
it's easier to lay down one mat, let it kick and then lay
down one mat and one cloth. The picture on the right are the
rear uprights which were gone through 20 years ago, but never
put on the car.
We will
re-coat all the castings, repaint the hardware and replate
the hubs.
Andy is
disassembling these. You can see the emergency brake under
the drive flange.
The corners
were in great shape, just needed restoration.
These
are magnesium castings. Most 906's had the same upright, but
some 904's also had magnesium uprights.
Don't
be confused, 904 and 906 uprights are different. In this picture
Andy has removed some spacers which center the brake caliper.
Sometimes these are used, most often not.
Andy is
pointing out where the spacers would go. When we mount the
rebuilt calipers, these spacers might not be needed.
The uprights
are now coated, the hubs are black oxide and the front hubs
are ready to install.
I have
been fitting sheet metal (fiberglass shrouds) on two engines.
In these pictures, you'll see the steps in installing 6mm
nylon nut plates.
First,
a 6mm hole is drilled between both panels. Then, the nut plate
is screwed upside down to the hole and 1/8" holes are
drilled. After one hole is drilled, the pop rivet is placed
in the 1/8" hole to keep the nut plate centered, then
the second hole is drilled. The nut plate is then installed
right side up, the 1/8" holes are countersunk, and countersunk
aluminum rivets are popped in. Most often, the factory used
solid rivets in these applications, but they also used pop
rivets which is ten times easier, so we do the same.
This is
the finished product.
Remember,
the glass shrouds come in 3-1/2 different colors. Sometimes
an engine would have all the colors between the 6 pieces.
The shrouds
have now been installed on both engines. In this picture,
the chain housings are gold but not all 2 liter racing engines
have the same colors on the cast parts.
This is
the engine for 127 and these are the parts. Some are still
new and you can see the part number is still on the chain
housing. Also, you can see the inside of these parts are gold
(platinum looking) and not olive brown or green. The later
two colors are seen on other 2 liter C6 or 910 engines. 911R
has the same castings and from one to another, these parts
could be any of these colors.
Close
up view of the housings. I obtained these 25 years ago and
127 had tired housings, so I replaced them with new.
After
the housings are coated, you have to re-epoxy the rail studs
and the tensioner shafts. They will leak oil if you don't
do this.
They look
pretty when they are done right. Hell, they look pretty when
they are done wrong.
