EM-22prose procedureInstallation (Cont'd)
IMPORTANT
Tightening procedure (bolts 1-10): (a) Tighten bolts to 39 N·m (4.0 kg-m, 29 ft-lb). (b) Tighten bolts to 78 N·m (8.0 kg-m, 58 ft-lb). (c) Loosen bolts completely. (d) Tighten bolts to 35 N·m (3.6 kg-m, 26 ft-lb). (e) Turn bolts 60 degrees clockwise. (f) Tighten bolts ⑪–⑮ to 6.3 to 8.3 N·m (0.64 to 0.85 kg-m, 4.6 to 6.1 ft-lb).

Timing chain installation (cont'd)
- 15Install idler sprocket bolt.
- 16Install camshaft, camshaft brackets and distributor bracket. Tighten camshaft bracket bolts gradually in three stages: (a) 2 N·m (0.2 kg-m, 1.4 ft-lb); (b) 6 N·m (0.6 kg-m, 4.3 ft-lb); (c) 9 - 11.8 N·m (0.92 - 1.20 kg-m, 6.7 - 8.7 ft-lb).If any part of valve assembly or camshaft is replaced, check valve clearance according to the reference data. After completing assembly, check valve clearance. Refer to "Checking" and "Adjusting" in "VALVE CLEARANCE".Reference data for initial setting of valve clearance (Cold): Intake 0.30 mm (0.012 in); Exhaust 0.35 mm (0.014 in)
