I should explain a bit better...
If you look at the first picture you'll see that the baulk ring is rotated one way as far as it will go but the spikes on the baulk ring are still only slightly misaligned with the splines on the hub. My theory is that this is not properly preventing the synchro sleeve from sliding past the baulk ring and grinding on the second gear.
The second picture shows the baulk ring rotated the other way as far as it will go and you can see that the baulk ring spikes are much more misaligned with the hub splines. This possibly explains why, although the 1st to 2nd shift used to grind really badly (like no synchromesh at all), the 3rd to 2nd shift was ok (although maybe a bit slow.)
This gearbox is one that I took out of my 110 a couple of years ago. It's been previously rebuild (maybe several times.) Shortly after I bought the whole LT77 setup from Ren Ching, I discovered that Ashcroft had started to remanufacture the 200tdi short bellhousings for the r380 so decided to use this on my 109 instead of the LT77.
