DO NOT reuse same bolts. Tighten new bolts in the following sequence:

STEP 1 = 14 ft lbs (19 Nm) STEP 2 = 29 ft lbs (39 Nm) STEP 3 = 36 ft lbs (49 Nm) STEP 4 = Loosen 3 Revolutions (DO NOT loosen all bolts at the same time. Loosen and torque to specs one bolt at a time.) STEP 5 = Short Bolt - 15-32 ft lbs (20 - 43 Nm) Long Bolt - 30-36 ft lbs ( 41 - 49 Nm) STEP 6 = Additional 175 - 185 Degrees Hope this helps.
