Tighten the short/inner bolts (17-20) third, in two passes.
Tighten the short/inner bolts to 30 Nm (22 lb ft) on the first pass.
Tighten the short/inner bolts (17-20) an additional 60 degrees on the 2nd pass.
Tighten the long/outer bolts (21-24) fourth, in two passes.
Tighten the long/outer bolts to 30 Nm (22 lb ft) on the first pass.
