Hi All,
I was changing gears around on the CQ6230 and turning by hand it felt a little sticky,
when I looked more closely the shaft of the lead screw gear box was not turning freely,
so after pulling the whole thing apart the problem was obvious. The shaft was running dry..
The oil way was blocked with crap, and so no oil was getting through to the shaft.

I cleaned it up as best I could and re-assembled it all. Seems fine now.. so I'll see how it goes..
But, I suspect that I just dodged a bullet, so this post is a warning to anyone else with a similar set up..
Check that the oil ways are clear. It wasn't at all obvious that it was blocked.
Regards
Ray
