FABRICATION OF A HEAT SHIELD

Realizing that the brake lines are installed in the same position as they were originally, they are in close proximity to the exhaust manifold.  Much to close for me.  So, I am fabricating a heat shield from sheet aluminum to prevent the brake fluid from over heating.  

I have two options.  One, is to fabricate a shield mounted to the frame shielding the brake lines; the other is a shield attached to the header accomplishing the same.  Attaching the shield to the frame is a bit more complicated.  Attaching it to the header is less attractive.  So, I plan to fabricate both styles and choose the one that will be the most effective and the least obtrusive.

REBUILT WEBER 45 DCOE

I admit,  the thoughts of rebuilding a Weber 45 DCOE was a bit intimidating.  After reading several internet articles about this subject, I was a bit more confident.  

The rebuild kit cost less than $30 and consisted mostly of new gaskets and "O" rings.  Including cleaning the carburetor, the rebuilding process was completed in less than two hours.  

After rebuilding the carburetor, I mounted it on the manifold so the fuel lines, throttle linkage and choke cable could be fitted properly.

Looks great doesn't it...

FITTING THE INTAKE MANIFOLD

After bead blasting the aluminum intake manifold, I applied a very thin coat of high temp silver paint.  The paint will prevent the raw aluminum from oxidizing.  

The flange thicknesses of the intake manifold and exhaust manifold vary by 3/16 of an inch.  To compensate for the difference, I attached a shim to the thinner flange.  Now the washer and nut apply the proper pressure to each flange preventing leaks.  Why can't these manufacturers engineer these parts to fit.  It isn't "rocket surgery".  But,  it is what it is.

Now, I am in the process of rebuilding the side-draft Weber carburetor.  As I explained in a previous post, the carburetor was clogged with dirt and varnish.  Cleaning is the first step in the rebuilding process.  This may take some time.

Stay tuned,

THE WEBER DCOE45 INTAKE MANIFOLD

At one point in time I was considering the purchase of a supercharger from Moss Motors.  Priced at $4000, it exceeds my current budget.  So, I have decided to install a side-draft Weber carburetor.  The carburetor is used and needs to be rebuilt but rebuild kits are not at all expensive.  

The photo to the right shows the intake manifold for the Weber.  Since it is made of aluminum, I can bead blast it and it will look new.  

I plan to dismantle the carburetor tomorrow and let it soak overnight.  I took a peek inside and it is "full" of dirt and "varnish".  

Love this car...

MORE ABOUT WIRING

After locating the fuse block near the firewall,  it was fastened in place.  The wires were then separated and moved to their respective locations.

Next, I went to work on the headlights. I began by fitting the new rubber gaskets behind the headlight buckets and fastening them to the opening in the fender.  

 After the buckets are fastened in place the inner rim is mounted to the bucket.  I replaced the adjusters, wiring and springs on both headlights just to eliminate any future problems.

Finally the headlights are positioned, just to make sure they fit properly.  The finish paint has not been applied yet so the headlight assemblies must be removed.
These headlights are really cool.  The signal lights are actually inside the headlight itself.  If you look closely, you can see the small amber bulb just below the center of the bulb.








The car will also have driving lights.  They will be located in the grille area.

Stay tuned,

THE WIRING BEGINS

We are almost ready to drive the "Killer B".  In order for the car to be "road worthy" (not necessarily street legal), we must complete the wiring,  attach the intake and side draft Webber carburetor and install the radiator.

The wiring is a bit complicated, at least it is for me.  In the photo to the right, you will see the wiring harness I purchased from ez2wire.com.  It is a relatively simple harness with everything labeled.  The labels are actually printed on the wires.  This should be easy 2 wire...wish I hadn't said that.

Y'all come back now...hear?

FUEL LINES ARE CONNECTED

There are always issues associated with assembling an MG using parts from different year models.  For instance, the fuel delivery system for a '67 MGB is entirely different from that of a '72 model.  It will work but it can be annoying choosing the correct parts from a catalog.  The system I have installed is custom fabricated and is very basic in design.

The photo to the right shows the new fuel line mounted in place.  It is routed through grommets in the frame underneath the right side of the car.  From there it is secured to the deck behind the engine and ends on the left side of the engine compartment near the intake manifold.  It will be connected to the carburetors with a rubber fuel hose.

Stay tuned,
