Just putting the gen 1 back together after doing the water pump seals, come to put the metal water pipe back on the engine (the short one under the gearbox sprocket) and what a pig to fit. Even tried a new o ring thinking that that was the problem, basically the thing will not go in and sit properly, I've tried putting the seal onto the pipe then trying to sit it home....no good, I've also tried putting the seal in the casing then pushing the pipe in, still no good.
I've ended up using a smaller o ring stretched over the pipe then it sits home ok but my concern is that it will leak, has anybody come across this before ??
