Thanks for all the replies and comments!
1608: I did try a bit with the chisel even if that is a bit out of my comfort zone. I removed most of it but after a while started to realize that i do not think I will be able to remove enough to just heat/drop it out. I am pretty convinced that I would still need to drive it out and I am reluctant (at this stage) to drill the holes needed to drive it out. I did try to heat the case (not very much) with a gasburner and banged it on wood, but it did not give a mm).
Also I am not sure that the puller I can find for a decent price can be fitted in the narrow gap if I want to pull off the inner bearing.
There are no visible c3 mark and the search on the number did not give much..
ajsph: Thanks for the tip! It really seem like an idea to test, however I am short on resources to get that piece of Al manufactured.. but i will keep it in mind. Thanks.
Duncan: I am doubtful..BUT I am glad you are pushing me and I will give it another try! I am doubtful as the outer bearings have a good chamfer and should centre the roller.. AND it works on the drive side... ..BT again, as you say, if this approach works it is the best/easiest! I will try with tape, no problem to try it and take apart again (unless it sticks.). Thanks!
1608: Thanks for the thoughts. And in one way I do completely agree with you. However,
firstly: I am not a very skilled mechanic and have a limited set of tools.
secondly: I usually do projects in 2 steps, first a quick and dirty to show it works (mainly for myself) , Then a second step where i go back and correct things discovered properly.
thirdly: In this case I need to balance the risk of damaging something in the process, my limited time available, my first level goal to show that it can run at all (!!), cost..
So, I know that the "right" thing to do would be to pull off/out teh bearing and race and check if tehy need change etc.. BUT there are many steps in that process that worries me.
As the crank turned freely when i got the engine, in boxes (crank case and shaft assembled). I assume that it would NOT damage the engine to run for a few hours assembled with that tight fit ? This assembly that i do now is intended for that first tests to see if I CAN get the engine to run at all without to large cost.
Duncan 2nd: I completely agree that it should be properly tested! (and yes bearings are bit expensive..)
Thanks you for all the comments and please continue to comment.
My current plan is now to:
1. See if it helps to keep rollers in place with tape! (easy test
2. Try to fit it together as is, tighten the web centre, mount cams followers etc, add gasket sealant, heating the case and then try to gently drive the timing case (and outer bearing race) in place.
3. if that does not work OR as a future fix, split the case and start to drive out the outer race, potentially followed by the bearing.
Thoughts on this ?
