   Been a while since I've rebuilt a TU....if the bottom end is at TDC, will no 1 and 4 pistons be at the top and no 2 and 3 be right down the bottom of their stroke?
   Got the drill bit in the locking hole at the flywheel, but I was expecting TDC to have all pistons sat evenly about half way up as they do on the XU engines. Just wanna make sure I haven't cocked it up before I go bolting everything down.

   (In english)
   
   Yeah that is correct, 1 and 4 at TDC are at the end of their stroke.
   
   Just remember when locking cam pulleys that these have two positions when bottom end is locked at TDC. Align the locking holes and you wont be far away.
