Thanks for the advice guys. bits removed and put in a safe place.
Have done a bit more this weekend, these bits are next to put together.

I did not replace this bearing but instead took out the plastic insert that holds the balls and gave everything a good clean.
You can see from the picture that the bearing will sit centrally on the shaft.
Now its time to put the gears into the box.
I dont know the correct sequence for doing this so I just placed the gears in making sure they sit properly on the selector forks and then slid a new mainshaft double roller bearing on.
Note i put the retaining clip onto the bearing.

Also at this stage you can see I have placed the oil pick up cage into the box. Dont bolt it up though as it needs to move out of the way a bit to get the layshaft in later in the build.
Next I placed the roller bearing onto the other end of the mainshaft.

Then the 1st motion shaft slides in and over the bearing. I then gently heated the gearbox around the areas where the big bearings go. I did this with a heat gun which normally gets used for paint stripping.
With the box nice and warm I then Gently drifted the bearings in, A small amount on the mainshaft bearing first and then the 1st motion shaft bearing.
The mainshaft bearing should be drifted in all the way to the retaining clip. Once both bearings are in its time to fit the big circlip.

The 1st motion shaft drive gear can now be fitted, dont forget the tab washer which locks into place via the two small holes in the gear.
I have not tightened the nut up yet (Just in case ive made a mistake).
Thats it then for now. Hope this is all making sense to you!!!

I have run out of memory space for the pictures now. Can any one tell me how to get more pictures onto this topic. Can I upload to photobucket and get them on that way, or is there a way of getting more than 50MB thread memory
