I have stripped the engine for a clean and check and am starting the rebuild. The first problem I have is seating the lay shaft/ counter shaft properly. The centre of the three selector forks does not seem to want to sit in the guide properly - it appears that the fork opening is too narrow to bed onto the shaft between the two fixed gear wheels (third and fourth) and this leaves the counter shaft too high so that neither end bearing will sit low enough. I have checked and rechecked the selector mechanism and I'm convinced it is properly installed. I have also been able to check both the counter shaft and the selector assembly against units from another machine and can't see any problems with the units themselves. Does anyone know if there is a trick to getting this installed right?
Any ideas gratefully received!
p.s. Please ignore the post. I just had a eureka moment. The centre fork links with the main shaft. Duh!

do we need to put the gear shift drum in Neutral position when reassemble? what is the best common practice?
I did and it seems to have worked out fine!
