Ok- we've got the layshaft out, that was a drift job.
This is the tailshaft housing off and the sump on the way
and this is the drift I knocked the countershaft out with, although I had to finish it with a steel tent peg as the drift wasn't quite long enough..
and this is what we got when we lifted the layshaft out. Two spacers at one end and one at the other. Now.... can we get new spacers?
