Cables and shafts transmit movements and readings in the Alfa Romeo 105 series and are used in the Giulia, Berlina, GT Bertone and Spider 105/115. These include the speedometer cable, rev counter cable, throttle cable, choke cable, heater cables and other Bowden cables. As a manufacturer, supplier and spare parts specialist for classic Alfa Romeo models, Alfa-Service carries a wide range of cables and shafts. The function is comparable across the series, but length and connection are often model-specific, because the routing and controls differ by model.
Alfa Romeo 105 Cables and Shafts at a Glance
The speedometer cable drives the speed display, while the rev counter is driven mechanically via a cable or electrically depending on model and model year. The throttle cable connects the accelerator pedal to the mixture preparation, the choke cable the cold-start device. Heater cables operate flaps and valves of the heating, while other Bowden cables perform individual control functions. The basic function is the same across the series, but the version depends on model, body and routing.
Cable and Shaft Part Types
The range is divided into the following part types:
- Speedometer cable
- Rev counter cable, where of mechanical design
- Throttle cable
- Choke or starter cable
- Heater cables
- Other Bowden cables and control cables
Shared Across the Series or Model-Dependent
For cables and shafts, length and connection are the decisive features, and both are often model-specific. The routing in the vehicle, the position of the controls and the body determine which length and which end fittings are needed. The throttle, choke and heater cables therefore differ between coupe, saloon and Spider, even though the function is identical. For the rev counter, it must also be noted whether the car uses a mechanical cable or an electric drive, since only the mechanical version requires a cable. The Giulia, Berlina, GT Bertone and Spider 105/115 thus share the design, while the specific version must be chosen by model and model year.
In practice it is advisable to determine each cable individually by length, routing and end fittings. Comparing with the existing cable on the vehicle is helpful, since cables that look the same can differ in length or connection. The speedometer cable depends on the gearbox and display connection, the throttle cable on the pedal and carburettor or injection connection. This makes it possible to assign cables and shafts specifically and without wrong purchases.
Notes on Part Selection
Decisive are the model, model year and the exact length as well as the end fittings of the respective cable. For the rev counter, the design (mechanical or electric) should be checked. As length and connection can be model-specific, comparison with the existing part is particularly important. Anyone who establishes the model, model year and routing can put together the speedometer cable, throttle cable, choke cable and heater cables reliably.
In the interplay, cables and shafts connect controls and displays with the respective assemblies. The speedometer cable is driven from the gearbox output and leads to the speedometer, while the rev counter cable, where of mechanical design, supplies the rev counter display. The throttle cable transmits the pedal movement to the carburettor or injection, the choke cable operates the cold-start device. Heater cables open and close flaps and valves of the heating. All these cables consist of an inner core and an outer sheath and carry model-dependent end fittings at their ends. Length and connection are therefore the decisive features for assignment.
Because the routing in the vehicle, the position of the controls and the body differ between coupe, saloon and Spider, even functionally identical cables differ in length and end fittings. A throttle cable from a coupe therefore does not necessarily fit a Spider, although both perform the same function. For the rev counter, the design decides: only the mechanical version needs a cable, while the electric drive does without one. The distributor or gearbox connection can also differ by model year, which is why a precise comparison on the vehicle is important.
In practice it is advisable to determine each cable individually and to compare length, routing and end fittings with the existing part. Especially on older cars it is worth using a worn cable as a sample, since cables that look the same can differ in detail dimensions. The Giulia, Berlina, GT Bertone and Spider 105/115 share the design of the cables, while the specific version is chosen by model and model year. In this way the speedometer cable, throttle cable, choke cable and heater cables can be put together reliably and without wrong purchases.
As a manufacturer, supplier and spare parts specialist for classic Alfa Romeo models, Alfa-Service assigns cables and shafts clearly by assembly and model family. The range covers the whole 105 series, so that the speedometer cable, throttle cable, choke cable, heater cables and other Bowden cables for the Giulia, Berlina, GT Bertone and Spider 105/115 can be found reliably. Since the design of the cables is comparable across the series, the right position can already be narrowed down via the assembly, while length, routing and end fittings are determined by model and model year. This classification makes selection easier, because functionally identical cables can be distinguished specifically by their detail dimensions.

FAQ
Which cables and shafts does the 105 series include?
Speedometer cable, where applicable rev counter cable, throttle cable, choke cable, heater cables and other Bowden cables.
Are cables and shafts usable across the series?
The function is comparable, but length and connection are often model-specific and differ between coupe, saloon and Spider.
What should be observed with the rev counter?
The design: only the mechanical version needs a cable, the electric drive does not.
How do I find the right cable?
Via length, routing and end fittings, ideally by comparison with the existing cable on the vehicle.
Is Alfa-Service a workshop?
No. Alfa-Service is a manufacturer, supplier and spare parts specialist for classic Alfa Romeo models and does not carry out repairs.
