  5. Was the little washer not meant to go under the bolt head? Good work on the box, new bearings are loads biggger

  6. came pre made there pressed on to the bolt and i thru the old ones in the bin so not sure if it was meant to be under or above ? :confused:

    thanks :) took me a while to do but its still notchy works fine could just be the new syncros bedding in or on the sevier side a bent/damaged selector fork
     
  7. Ah right, odd design then.

    Hopefully it sorts itself out (y)
     
  8. Looking at that I would say the bolts were wrongly made. The spring washer should have been on the head side of the large washer not the bush side.
     
  9. it was not a spring washer thats just where i cut it and bent it off :) i dont actually know what the originals look like lol

    seams a bit better today think i may need to bleed the clutch again and im sure there's something different with the clutch pedal like its stiff in the last part

  11. Next step on the 6speed conversion
    Ive managed to get a real clean and tidy corsa vxr box for a price im not saying as it turns out the box dont even need the 6th gear bearing doing
    IMG_20171112_154820.

    Even the inside of the bell housing is clean
    IMG_20171112_154829.

    Gears all look good
    IMG_20171112_161028.

    Counted the ring and pinion 71/17 so it is the 4.17 fd
    IMG_20171112_162037.

    Next step mix and match to get the box i want 4.17 fd with 1-5 astra gears and the diesel 6th :)

  12. Could be easyer than i thought the corsa box uses the same MZ0 gears as the vectra box Screenshot_20171113-090403.

    Swap the diff and fit the diesel 6th then put the revised end case on
    Screenshot_20171113-090424.

    But i think im going to change the large bearings on the pinions in the process
