An interesting concept.> If you've got a pre 1993, I would seriously recommend a Jake Jakeman > Sprocket Retainer and Shim set...
The design of the retainer has bugged me for some time. The retainer only seems to be about 1/2 spline out of line, where most people would put the splines in the retainer one whole spline out of line so that the shaft splines contact all of the spline on the retainer. Maybe one day when I fit a new retainer, I'll slot the bolt holes in the retainer to move its splines around a bit further. The other thing to consider with that design of "floating" sprocket is that the life of the shaft splines might be improved with a bit of chain lube onto the splines whenever the chain is sprayed. Since the sprocket will move around a bit anyway, it might as well be lubricated when it does it. I don't recall the manual mentioning any need to lube the splines, but the stock sprockets are not higher quality, solution heat treated steel like the ones I use, so the stock sprocket centre should wear a fair bit more than the shaft.

[...] Ah, this is new information. From the above, it may appear that there could be a crack in the casing which is opened up when the seal in pushed into its bore.

You're totally right, I am lucky enough to have only heard about this phenomenon on the list and never had to deal with it first hand.> I would think that a loose output shaft bearing would be a better > indication.
My father is sending me his big ass Nikon macro lens with a ring flash on it so that I can get some good pics of how the Jake Jakeman retainer teeth *completely* overlap the CS splines. The retainer is also about twice as thick as the stock and being that Jake is much better machinist that KHI, I had to touch up the retainer teeth with a file, as the groove on the CS was not well machined from the factory. Comes with 10.9 grade bolts as well.> The design of the retainer has bugged me for some time. > The retainer only seems to be about 1/2 spline out of line, > where most people would put the splines in the retainer one > whole spline out of line so that the shaft splines contact all of the > spline on the retainer. > Maybe one day when I fit a new retainer, I'll slot the bolt holes > in the retainer to move its splines around a bit further.
If you were to look at the new style sprocket retainer system (the 28mm nut), I think you'll agree with me that KHI moved to that so that the floating sprocket UDF would not be a problem. I think that this was another UDF by KHI which they should have fixed with a thicker, machined retainer that is spaced properly (as Jake's is) rather than a big ass unwieldy nut that is a friggin pain to change in the field. Who the heck wants to carry an 18" breaker bar and socket with them? On my A5 all I need is my 10mm socket wrench. I have been running PBI sprockets, which I would assume are better quality than stock, but since that has only been within the past 1000 miles, I think that the majority of the wear on my splines was from the stock sprocket and the 'floating' sprocket UDF (i.e. about 8,000 miles). So that is why I think its worth moving to Jake's kit ASAP if you've a pre-1993... I feel it is a great $20 of preventitive maintenance.
