LT230, input gear. On the face of it, it ought to slide out, but it bloody doesn't. and for why? the gear on the intermediate shaft behind is isn't too big (appears to be the same size), but the bloody thing's out of phase such that the teeth run into eachother, buggrit.
1.192 ratio, if that makes a difference. arse.nemmind. There's play in the shaft, but I'd be amazed if there wasn't on a second-hand LT77/LT230. looks like under 1mm measured around the shaft.
What I think I'll do is get it swapped, and then have a think about rebuilding the one that's in there, depending on what the replacement feels like.
