• Received wisdom suggests SA hubs are difficult to work on, and I believed it until I retired and had the time to give it a go myself.

    I've stripped cleaned and re-assembled several utility bike AW hubs from the mid 50s (one sacrificial in case I couldn't do it, one to actually use and one as a spare) following YouTube instructions - given plenty of time and bench space to lay parts out in an exploded view manner, and it seemed quite doable. For reference I took photos at every step just in case. All seemed to have much the same problem - thick oily sludge, possibly from the wrong oil or inadequate dust sealing, very little actual wear, all now work fine.

    Looking at exploded views, I think the AM looks similar in construction to the AW - would you have time to strip and rebuild a relatively cheap eBay AW by way of informing decisions on servicing?

  • I don't have the space really to lay it out like that, it would have to be in the house and if the cat found it It would be doomed. Also, even if I do have the time, I'm not entirely sure I have the patience! I could try on a cheap sacrificial AW though first I suppose....

  • Assuming just a hub not a wheel, probably no more than 3' x 1' bench space and possibly a selection of jam jar lids or similar to group things in. If memory serves, I needed roughly four hours (though not all in one go) for the first one, less than three for the most recent. Possibly the cat would be the biggest problem? (NB this is unsolicited advice from a man with time and space but no cat)
