When I first bought the car the speedo was jumping, the DPH told me that it was the cable and he even had a spare which he gave me.
Well loyal readers (if there are any) you may recall I have changed the cable twice (the spare from the DPO was for a RHD car) and bought a new speedo.
The last attempt before replacing the gearbox drive pinion (which is NLS**) is to change the angle drive on the gearbox. This takes the output from the gearbox and turns is 90 deg to make the angle for the speedo cable softer.
Here it is (note the new cable from a previous attempt).
Hmm, something missing.
Here it is
Where ? Here :-
Its the male pin on the angle drive.
Old and new.
And . . . . . . . . . YES it works, I finally have a Speedo !
** NLS = No Longer Sold, and it means TROUBLE.
Next . . . . . . Hmm, we'll see.
