850 gearbox problem

[jim mac]

i had to pull the gearbox on my T5 again.  Lifting the cover was a bit of a prob, took a lot of levering and gentle bashing.  at one point the internals started to lift about 1/2inch so i started again.

got cover off and when replacing found tghat the gear selector drum appears to be too high in the box to allow cover to go back on.  it seems solid with no lateral movement,  i dont want to pul to hard in case i do something else - has it lifted out of its seat  ?  the Cluster shaft also appears to be high  do i need to strip the box out to fix it  -  or is there an easy fix anyone know ?

I have a copy of Pete Roper's guide

Could have lifted and a shim slid over.

Make sure it's in neutral when assembling or disassembling. Agree with Steve that a shim has likely shifted and is blocking reentry.

How do I check it is in neutral  with the box out ?

Well if the drum is sitting proud then the selector forks can't be engaged. Pull out the fork shaft and remove the forks and re-seat the shafts and then the drum.

Make sure to remove the shift detent.

it was the shift detent under the drum, all sorted - thanks to everyone
