1973 240Z Restoration - Inspecting Major Components
Next step - investigate state of major components...
Since we have completed our initial inspection of this 1973 Datsun 240Z, it is time to start disassembly and cataloging all of the parts. Having a complete and original car in the shop is always nice. As you are pulling things apart you discover various little bits that are often lost or simply removed from these cars from years of use. It serves as a pleasant reminder of what was really in there off the assembly line.
Inside the cabin there are a few things very apparent in need of attention. The most obvious is the dash that has a few cracks present. Our 2 recommendations in this situation is for a fully Refinished Dashboard and high quality glue down Dashboard Cap. These solutions fit various needs and budgets and both yield great results for their respective price points. Our customer has elected to install a Dashboard Cap, which will be installed once we come to working through the interior. With the largest, most time consuming part of the interior planned, we take note of a handful of other items requiring refreshing on the interior, but we will touch base on those in another post.
Moving outside of the car, we take a look under hood and see this car is equipped with a set of Weber 32/36 Carburetors. These are a nice change from the flat top Hitachi SU carburetors that were originally in this 1973 and can be so finicky. Many 1973-74 Datsun 240Z and 260Z owners installed the 32/36 combo into their Z’s or moved to the early (1970-72) dome-top Hitachi SU carburetors. Rather than replacing the carburetors, the units in this 240Z will be receiving a light refresh and rebuild using our Carburetor Rebuild Kit as they are in pretty nice condition. Keeping carburetors running smooth and balanced is key to engine longevity. Running lean on one carburetor will have half the engine running at a different cylinder temps on those 3 cylinders compared to the other 3. Healthy carbs make for healthy cars.
As highlighted on our last post, it is known that we have an engine that is in need of rebuilding. With this in mind we are giving this rotating assembly the attention it needs with a Master Engine Rebuild Kit, which is essential to our Engine rebuilds. (If rebuilding an Engine yourself is not in your expertise, our Rebuilt Engines and Cylinder Heads for the 240Z, 260Z, 280Z or 280ZX are great options.)
With the Engine separated from the transmission, we now have the opportunity to do some basic inspections with the 4 Speed Gearbox. While this unit by appearances is in workable condition and just in need of a good cleanup, we are prepared for any trouble that could arise. A Transmission Rebuild Kit is at the ready if any crunching or whirring is observed once the 240Z is road-going again. Just behind the transmission, are the driveshaft and the rear differential. These too are in a state of limbo pending getting the car back to proper health. If concern is present with either of these components, U-Joints, Halfshafts, Driveshafts, Complete Differentials, and Rebuild Kits are all waiting for a call to the bullpen.
We are progressively chipping away at the rehabilitation of this time capsule 1973 Datsun 240Z. Stay tuned to follow our progress and see this journey continue...
