Use new bolts....
1) tighten to 30 Nm
2) tighten further 80 degrees
3) wait 3 minutes
4) tighten bolts 1 and 2 (the centre ones) 25Nm more, then a further 213degrees
5) tighten bolts 3 and 4 the same
6) tighten bolts 5 and 6 the same
7) tighten bolts 7 and 8 the same
8) tighten bolts 9 and 10 the same
Well, you did ask....! Number 1 bolt is centre rear, number 2 is centre front, number 3 is one to the left of 2, number 4 is to the rear of 3 and so on. See? You are tightening in a clockwise spiral, starting from the centre. Enjoy.....!
