New Chain = New Gears. I never even bother looking at the condition of what comes off.
As Unburnt suggested, a Duplex set up for a Road Car.
Does the duplex set up require any modification to the timing cover? Specifically on a later A+ 1275
Most A+ covers have a dimple in them, looking from the front of the cover as it would be fitted on the engine, it's at about 4 O'Clock. These need leveling out with the rest of the cover. Some have said the reinforcing ring (or part of a ring) on the covers that have the Oil Separator also need to be removed, however, I haven't found I've needed to do that.
Apart from the mods to the cover, there's also 2 countersunk screws that need to be fitted in place of the 2 hex head bolts at the bottom side of the engine plate.
