Orion speedo - captain
My 1991 Orion 1600i Ghia has a faulty speedo. Now its not the cable as can spin this by hand so must be gearbox as cable coes not turn when driving. Any ideas!!!

Check the speedo drive pinion in the gearbox, it's held in with a roll pin and it can be a bit of a fiddle getting the pin out. The gear driving the pinion sits next to the diff bearings, if the plastic gear is chewed up, chances are that the diff bearings are worn allowing misalignment. Gearbox needs rebuilding.
