Our burglar alarm after one of the bathroom fitters sliced through the cable from the kitchen door sensor and knocked out the auxillary fuse in the control box stopping the whole thing from working – gel-filled B-crimps to splice the six-core cable back together and an 800mA glass fuse in the control box. And yes I did cut mains power to the latter before opening it up. All quite straightforward, no engineer code required to reset the alarm afterwards. Result 🙂
Also, a 2017 Wahoo Kickr. Changed every bearing in the thing – pulley wheel, fly wheel, free hub, belt tensioner pulley, all done. Just waiting for a new drive-belt to replace the visibly distorting one that’s been on there for the last couple of years. No thanks to Wahoo for being miserly with both information and spare parts – they\d clearly rather I’d buy a new trainer.
The crux of the thing was getting the bearing that’s hidden behind the ratchet ring on the pulley wheel out. There is no tool available, the 2014 3D printed one won’t fit, apparently. I eventually got a local precision engineering shop – they’re always ‘precision’ because who wants to be a ‘roughly in the ball-park’ one? – to bore out the metal between the two bearings, so they could be pressed out without removing the ratchet ring, and replace the missing metal with an equivalent spacer. Seems to have worked fine and means if it ever needs replacing again, they can both come out the same way with no need to mess about with the ring.
