I'm in the process of doing up an '86 Triumph 20. There are two knotty problems bothering me the first of which is, why is the three speed Sturmey Archer hub occasionally dropping out of gear when I'm in second?
Anyone got any clues? (I'll deal with the second problem another time...)

Where the gear cable joins to the "do-hickey" is called the adjusting barrel. Loosen off the lock nut then turn the AJ (slightly), either way until your problem is fixed....tighten the lock nut. It could just be that the cable is too tight/loose. Make sure when you adjust it you make minute turns. Do this in 3rd gear.

Thanks Stevegor. I thought I had it bang on. I'll give it another go but I'm worried that I'll fankle up 1st or 3rd.

IF and that is a might big if you have the correct indicator chain, the easiest way to get close is to put the bike in second gear then adjust the cable until the shoulder of the indicator just comes even with the end of the axle. You have to be looking though the hole in the side of the axle nut. Then you may have to give a 1/4 turn plus or minus to get it dialed in exactly. You aren't going to break anything or mess up anything by tinkering with the setting. AW hubs are pretty tough.

That's great Aaron. If the first suggestion doesn't work I'll try that. I got the indicator chain when I bought the bike but it's not the original so it's a big if indeed!

I use the first method and it works as stevegor described. I bought two spare indicator chains on the internet.
