You won't have a problem torqueing it back up. The reason that its so tight is this
Torqueing the bolt up is the same rotational direction as the engine. The bolt over time further torques itself using the inertial force of the engine. (we used to get this on the aft heads jesus nut on the chinook helicopter, we usually ended up drilling the nut off as theres ***** all you can do when the 7000 Lb F Ft multiplyer won't move it). So basically its going to be significantly higher than 200 lb f ft of torque to remove it but you only have to put 200 Lb f ft of torque on it when you do it back up, which is torque wrench tight not ten white knuckles and bust a blood vessel in your head tight.
