Re: Looking for an RD04- How to check sprocket wear?
You must remove the sprocket as the outer splines will look good, is the ones after the ring that wear, new splines are aprox 4mm wide anything less than 2mm is worn and will need replacment of teh drive shaft. Also check for vertical or side to side movement of the shaft this will identify any play in the bearing shaft which is an engine out and plit job to replace!! As mentioned above wheel corrosion is also something to look for.
