For Sale, Magneti Marelli Distributor S125

The distributor was disassembled and the body was gently glass bead blasted and is perfect. The distributor was only reassembled and not rebuilt or adjusted. Everything is there. The Magneti Marelli S125 was the default distributor for the Dino 2.0l/2.4 V6 engine. This particular unit was included in the sale of a 1967 Fiat Dino which I bought and have restored. I have no need for this extra distributor.

The following is information found on the internet:

"Magneti Marelli Distributor S125

Cars with a factory installed S125 Distributor:
Dino V6 based cars with a Magneti Marelli AEC 101 or AEC 103 ignition

Variations:
S 125 A - 15° (1967-1968): 3 cams, two sets of contacts, early Fiat Dino 2.0 Spider and Coupe
S 125 AX - 15° (1967-1968): 3 cams, two sets of contacts, early Ferrari Dino 206 GT
S 125 BX - 15° (1968-1972): 3 cams, two sets of contacts, Ferrari Dino 206 GT and 246 GT, Fiat Dino 2.0/2.4 Spider and Coupe
S 125 C (1971-1975): 6 cams, two sets of contacts, Ferrari Dino 246 GT/GTS, Fiat Dino 2.4 Spider and Coupe, Lancia Stratos HF

The Magneti Marelli S125 was the default distributor for the Dino 2.0l/2.4 V6 engine, the 15° degree number after the type number denotes the maximum cam shaft advance. S125 A type distributors are the earliest type and were installed in early Fiat Dinos with a points and coil based ignition before the Dinoplex was introduced. S125 AX type distributors were installed in early Ferrari 206 GT's. S125 BX were produced between 1968 and 1972, a second batch was produced in 1974. S125BX distributors produced up to April 1969 had a silver on red label, for the rest of the production run the labels were red on silver. The S125 C distributor was introduced in December 1971 and also featured a 15° maximum advance, but this was no longer mentioned on the type label.

The S125 rotor turns counter clockwise. Turning the distributor clockwise will advance the timing, turning it counterclockwise will retard the timing.


S125 A, AX and BX type distributors have a three lobe cam with two adjacent set of points wired in parallel to reduce point scatter and enhance dwell at high RPMs.

S125 C type distributors have a six lobe cam and feature two independent sets of points for emission control equipped cars. In the emission control setup, the first set of points (R1) was always active, and the second set of points (R2) could be added by switching ground to R2 via a microswitch (which was installed on the left Weber carburettor) when no throttle was applied.When idling this setup retarded the idle advance by 5.5° (camshaft) for better combustion and cleaner exhaust gases.
S125 C distributors have the same body as S125 BX distributors but are easily identified by the second hole for the additional R2 contact terminal on the left of the distributor body.

For supporting the points based emergency mode in a Dinoplex AEC101/AEC103 setup, a 0,25uF capacitor was installed on the S125A/AX/BX body (two on the S125C) and wired to the points terminal. The Dinoplex ignition itself does not require a capacitor wired to the points as it uses the points setup only to trigger an ignition. The original capacitor supplied by Magneti Marelli came in a brass colored metal enclosure which was embossed with the Magneti Marelli logo, a production code (as example CE29T, ES29S) and the specification 0,25uF and 500 Volt."
