.... does anyone know if new Flavia bearings are still available at reasonable prices (i.e under a £100).
Not sure if you are a member of the Flavia Consortium and you may mean "new" when you say "new" but they recently fixed me up with a reconditioned clutch release bearing (new bearing installed in second-hand housing). After the cost of the bearing AND Consortium membership you would still have change out of £100.
The Consortium also offers availability and good value in reconditioned Flavia water pumps (I recently heard of a prominent Lancia parts supplier asking over 4 times the Consortium price - though that may have been for a new original pump) and access to many, though not all, other hard to get Flavia items.
I understand Fulvia and Flavia clutch release bearings are similar but different (being presumably designed for different clutch loadings) though I expect that as some Fulvia/Flavia gearboxes are physically interchangeable so too are the release bearings, if perhaps at the expense of shorter life if used with the wrong clutch plate?
I had engine and gearbox out following gearbox input shaft ("quill shaft"?) failure last year [pic] and this was something I really didn't want to take a chance on by finding after reassembly that I had matched the wrong things together. Happily everything worked fine - though I do have noise in the replacement gearbox both at idle while stationery and while in motion .... except in top I think - I find the "going fast theory of worrying noise abatement" applies.
