Freehub compatibility

I need a new freehub for my Shimano R501 wheels. From Shimano's exploded view, the part number is Y4SK98080.

I remember that Shimano used to do a chart showing compatibility between the different freehub bodies for each hub type (with an A/B/C next to each part) but I can't find it. Does anyone have a link to it?
(This is not the one I am thinking about).

Wiggle have a freehub body for £19.99 which says that it is compatible, but in the past it's been cheaper to buy a new hub and swap the freehub bodies hence needing to check which hubs use the same freehub body.

    Is it cost effective? You could replace the whole wheel for about £50

    You think you'll find a rear hub complete for less than £20??

    I always look on Shimano Tech Docs for compatibility, but they are always pretty restrictive in what they say works with what.

    I really wouldn't bother. Surely if you've managed to wear out the hub, the rims must be close to their wear limits? R501s are essentially consumable wheels - they're so cheap you might as well just replace the whole set. Last time I looked they were, what, £75 on Wiggle?

    It's perfectly possible to bugger a Shimano freehub before the rim's worn out, you just need to fill it with salty water without realising it, and leave it to marinate for a few weeks in a damp shed or garage...

    SJS Cycles also have the freehub for £20. That looks like the cheapest fix.

    Unless you fancy stripping down the dead one? It can be done but it's quite fiddly and involves dozens of tiny bearings. Have you tried simply picking out the seal and flushing it out and filling with a couple of changes of something like engine oil? I do mine on an annual basis to keep them sweet.

    I finally got around to trying to fix this, and the same on another bike.

    You can get rear hubs quite cheaply if you wait for them to go on sale somewhere: http://www.tweekscycles.com/Product.do? ... Gwod8P4HLA

    I got a couple of hubs at Icebike in the garage sale, however the freehub bodies aren't compatible with the R501 hub (or my Deore XT hubs) and the splines are a larger diameter:

    Do the hubs have the correct number of holes to allow you do a bit of wheel building? Or are the 501 spokes not the simple J-bend type I have on mine?
