Gear linkage bushes?
The cross gate action on my 156 JTD had got very stiff, so on Saturday I had a look at the linkage mechanism at the gearbox end.
I removed the battery tray and battery to get at the linkage, disconnected the cable and it was clear that the stiffness was in the pivot mechanism.
When I pulled the pivot lever out of the casing (or more accurately, drifted it out with a large hammer) the stiffness wasn't due to corrosion inside the casing or on the lever, but was due to one of the plastic / nylon "top hat" bushes being chewed up (there's one in either end of the casing that the lever passes through)
I believe you can get these from Alfa, but does anybody have a part number? I can't see them listed on eper.
