C0.5 Engine
Illustration 2 g01112400Use the following procedure in order to tighten the bolts for the cylinder head.
Put clean engine oil on the threads of the bolts. The bolts are tightened in the numerical sequence that is shown in Illustration 2. Torque for bolts C0.5 ... 36.5 N m (26.9 lb ft)
Repeat the procedure in Step1 to ensure that all of the bolts are tightened to the correct torque. C0.7, C1.1/3011C and C1.5/3013C Engines
Illustration 3 g00900073Use the following procedure in order to tighten the bolts for the cylinder head.
Put clean engine oil on the threads of the bolts. The bolts are tightened in the numerical sequence that is shown in Illustration 3. Torque for bolts C0.7 ... 36.5 N m (26.9 lb ft)C1.1/3011C ... 51 N m (37.6 lb ft)C1.5/3013C ... 101 N m (74.5 lb ft)
Repeat the procedure in Step 1 to ensure that all of the bolts are tightened to the correct torque. C1.6 and C2.2/3024C and C2.2/3024CT Engines
Illustration 4 g00900074Use the following procedure in order to tighten the bolts for the cylinder head.
Put clean engine oil on the threads of the bolts. The bolts are tightened in the numerical sequence that is shown in Illustration 4. Torque for bolts C1.6 ... 51 N m (37.6 lb ft)C2.2/3024C and C2.2/3024CT ... 101 N m (74.5 lb ft)
Repeat the procedure in Step 1 to ensure that all of the bolts are tightened to the correct torque. Measuring the Distortion of the Cylinder Head
Illustration 5 g00900977
Typical example
Distortion of the cylinder head ... 0.00 to 0.05 mm (0.000 to 0.002 inch)Maximum service limit ... 0.12 mm (0.005 inch)Maximum limit for regrinding ... 0.15 mm (0.006 inch)Note: Use a straight edge and a feeler gauge to check the six positions for distortion.Refer to Testing and Adjusting, "Cylinder Head - Inspect" for the procedures for measuring the cylinder head.Note: If the cylinder head has been machined, check the valve depth below the cylinder head face. Refer to Specifications, "Cylinder Head Valves" for valve depth.
