astra g 6 speed conversion adventures

[evocarlos]

so here is my 6 speed conversion adventure it will take a while but i now have the box and shafts
time to get the clutch changed and the attaching parts to make it work

thanks to 20vt for the box

removing the engine and gearbox the technical way




got the box on the bench to inspect the outer bearings and the diff planetary shafts Daz knows about this


case looks good no damage to the alloy case at all and the bearing faces look good


one bearing is showing some signs of wear but not that much
all the gears look good and the magnet don't have much on it


outer case got cleaned with bilberry wheel cleaner


looks nice and clean inside now


the progress will be slow on this one but hope to have it fitted to the car before the engine get put back together

diff looks good to

 

[Matt]

Is it an M32 you are fitting Carl?

 

[evocarlos]

yes matt im eating my own words lol but i know that with a astra vxr/vectra c gearstick and astra vxr cables it will fit

 

[Matt]

yes matt im eating my own words lol but i know that with a corsa vxr gearstick and cables it will fit

As long as you have got it apart, and you know it's put back together correctly, it should be fine.

 

[evocarlos]

they fall to bits there easy to take apart and put back together you just have to remember to fit the shim on the diff
a new full bearing kit is £80

F40 in the Vectra aren't they?

 

[milo]

Not sure I just assumed it was the m32 as was a 6 speed and what u said about the timing chains lol

 

[evocarlos]

yeah f40 is the stronger box 400nm from the factory the m32 is 340ish

 

[milo]

Would an f40 fit into the coupe? and how long u planning to have your coupe off the road for now??

[corsaZ22se]

good work. be good to have the taller top gear.
any corsa d 6speed cables should fit not just vxr, more chance of getting s/h set.

 

[evocarlos]

ok Daz vocky
timken or SNR for the replacement bearing ?

 

[Daz]

Umm

Never heard of snr, so can't comment, but timkin are good

 

[evocarlos]

ok i got it now
timken are the originals that fail more often with the metal cage
the SNR are the upgrade with the plastic cage and bigger race


timken on the left snr on the right


it also looks like there is a case mod to combat the oil starved bearing


i called my local machine shop and arranged to have the case acid dipped and cleaned up the same way i have the heads done
had to strip all the parts from the case for a proper job
selector out


gear clusters out


laid out on the shelf


no broken teeth


inner races are showing signs of wear


slave cylinder removed and input shaft seal out


the big bit


the other bits

 

[corsaZ22se]

you going to replace all the bearings while its apart?

 

[dewismotorsport]

My mates selling a quaife diff for a M32 if you fancy upgrading while its in bits

 

[vocky]

you going to replace all the bearings while its apart?

you should replace them as a matter of course whilst the box is apart, I used Timken in mine which have been fine
