Intermittent Gear Selection Issue.....

[Oldman]

Ok, update on this issue.....that is now issues ....
Took my bus out to my mechanic to see if he could find out what's going on.
Dropped the engine and separated the gearbox to check the clutch components .
As soon as the gearbox was separated, the needle bearing on the end of the crankshaft just fell apart......great ! 
Looking at the gearbox, with nose-cone removed all components were in place and working perfectly....no distortion or crack in that support bracket.
At the back of the gearbox however, the pinion had play within its bearing - ie the bearing was perfect but there was slop between the pinion shaft and the inner race.
Prognosis is that the case hardening has failed and the shaft itself has started to wear......great....again 

So, everything is now in the parts washer prepping for calibration prior to re-building.
Unfortunately it's not going to be completed, run in with appropriate services prior to Easter, so we've had to cancel our Bus Stop plans.

It never rains, it pours.
