(a) Wet , apply lubrication oil to the threads of the nut and bolt.
(b) 2-step tightening method,
(c) Tighten cylinder head bolts according to the angle method, tighten to 294 Nm [30 kpm; 217 lbf.ft], then tighten 60° more.
(d) Extremely important to use torque wrench in tightening the piston cooling nozzles. Failure to do so may result in excessive
tightening torque, which may cause valve malfunctions that could lead to seizing of pistons due to insufficient lubrication.
(e) Tighten connecting rod caps according to the angle method, tighten to 245 Nm [25 kpm; 181 lbf.ft], then tighten 60° more.
(f) Left-handed thread.
(g) Apply Moly Disulfide to thread.
(h) Tighten the lock nut to 49 Nm [5 kpm; 36 lbf.ft] firs, then loosen it completely.
Retighten to 14,7 Nm [1,5 kpm; 0,8 lbf.ft], then tighten 80±3° more.
(i) Tighten the lock nut to 69 Nm [7 kpm; 51 lbf.ft] then loosen it completely. Apply Loctite No. 962T to the threads.
Retighten to 9,8 Nm [1 kpm; 7,2 lbf.ft], then tighten 90±3° more.
