How many kilograms should the cylinder head screws of the Bora be tightened to?
1 Answers
The cylinder head screws of the Bora need to be tightened to 8-9 kilograms, the connecting rods to 5-6 kilograms, and the crankshaft to 10 kilograms. Method for tightening cylinder head screws: First, tighten from the middle to both sides, initially to 50% of the final torque, then loosen them all. Next, tighten again from the middle to both sides to 50%. Finally, follow the same middle-to-sides approach to fully tighten the cylinder head screws. Precautions when tightening cylinder head screws: Do not overtighten, as this can cause excessive stress on the bolts, leading to stripped internal threads or even breaking the bolts. Therefore, always confirm the torque specifications before tightening.
