WI are rebuildable, yes, but getting parts that make it economically viable? I have a couple kicking about the place that require new outers, new bearings and probably pawls before too long. bearings seem to last a year to 18 months for me, the outer lasts ~ 2.5 years. This last one I have on now is looking very hooked but is still going. The two I have laying around I have broken a tooth off each.
If I keep a WI going for three years ( let’s say ) it will cost about 85 quid ( bearing ~ 15 quid IIRC ) at UK prices. Yes, they work nicely, yes they make a great noise, yes, when this one fails I will replace it, but I don’t think it’s worth a complete rebuild on the old ones that require the outers, unless someone has the skinny on some good prices for spares?
Shame – there’s a big old hunk of Stainless there. They’re not actually bad value, even at RRP, when you think how much effort must go in to them.
How much are the Halos? are the bearings replaceable?
