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

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.

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

Ah right, odd design then.

Hopefully it sorts itself out (y)
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

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

Even the inside of the bell housing is clean
IMG_20171112_154829.jpg

Gears all look good
IMG_20171112_161028.jpg

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

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

Could be easyer than i thought the corsa box uses the same MZ0 gears as the vectra boxScreenshot_20171113-090403.png

Swap the diff and fit the diesel 6th then put the revised end case on

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

still quite clean
WP_20171219_17_54_31_Pro.jpg

cleared some space on the bench and got to stripping it down
WP_20171219_21_20_37_Pro.jpg

yep the diff is still there lol
WP_20171219_21_20_44_Pro.jpg

press came in handy for the bigger bits
WP_20171219_22_19_27_Pro.jpg

and for pushing off the 6th gear off the input shaft
WP_20171219_22_24_57_Pro.jpg

all parts checked and laid out ready for when the new bearings arrive

and people keep saying the f23 is better had nothing but trouble with both of mine
the m32 in both cars have been better overall smother changes better fuel eco with the use of 6th and the convenience of being able to do a 98% repair without even removing the bellhousing i say 98 cause the one part the input shaft seal you cant do unless you take the bellhousing off
