XT600 Engine rebuild questions (crank, bearings, valveseals etc)
Hi all,
New here with a XT600Z 3AJ from 89.
I'm currently in the progress of rebuilding the engine and have some general questions:
1) I've seen an excellent topic here from 8 years ago regarding bearings ( this one ) and was wondering if there is any update on this?
Is C3 sufficient for a lot of KMs or is it recommended to use C4?
I'm thinking about replacing all bearings with SKF/FAG ones. I can get C4 SKF for 25euros.
2) If I want to get the main bearing off of the crank, I will need to put it back in the same spot with a gap in between the crank and the bearing. Is this a fixed gap or do I just measure it and put it back approximately? It seems kinda vague to me.
3) I'm also replacing the valve seals. Are aftermarket ones any good? OEM ones will be €50 total...
4) I can also order everything aftermarket from Kedo.de (bearings, valveseals), but there's no info on these items. Are these any good?
Thanks!
