Main gearbox shaft axial clearance

Could any one tell me what the axial clearance should be on the main gearbox shaft as I have finished doing a dry assembly but find that it has 0.05mm max (that’s with the right side bearing as far out as possible) , side to side clearance were as the driven shaft (sprocket) has perhaps up to 0.5mm. It's this usual situation?
 
i believe that it's in engine rebuild in the doc. might be wrong not sure.

just a month ago we had a thread on a whining noise from the gearbox. joeusa cured his and has left a hyperlink to his eeven older thread.

so go look in (probably) mechanics in the forum section and gearbox whine etc as the topic subject.

HERE:
Gearbox noise/whine
It could be you can hear a noise coming from a 'whining' gearbox. This is noticeable at any speed, any gear, any time. If there is too much endfloat in the output shaft gears will rub inside. It's not dangerous but is avoidable at a rebuild. By using thicker shims the float can be reduced from a noise inducing.020"(0.5mm).008"(0.2mm). JoeUSA has the answer!

HERE is the thread:

go into rebuild for some great photos.
