F7P F7R Cylinder Head Bolts Tightening

Before you start
Wind all ten bolts in by hand then out again, this makes sure there's no dirt or anything in the threads. Then if you've got grease with the head bolts, apply some of that to the bolt threads and under the heads. Wind the bolts in til they are finger tight.

Stage 1 - first tighten
Right now get your torque wrench with a long T55 bit. Tighten all the bolts to 30Nm but do them IN ORDER, which means do the 2 middle bolts first then spiral outwards (see diagram)

Stage 2 - second tighten
Next, go back to the first one and tighten it more, up to 50Nm. Walk away and make a cup of tea.

Stage 3 - loosen
After a few minutes loosen them all right off but don't take them out. Do this in BACKWARDS ORDER so you loosen the outside ones first and middle ones last.

Stage 4 - final tighten
Now you are ready for final tightening. With the torque wrench do them up to 25Nm, in a spiral like the first time you did it.

Stage 5 - angle tighten
Once they're all done, go back again and turn them all by another 107 degrees. To help judge 107 degrees you can get dials to attach onto the wrench or you can make one out of cardboard. 107 degrees is just past a quarter turn to give you some rough idea but do it properly.

End.
