   2. Since front timing chain case is offset for difference of bolt holes, tighten bolts temporarily while holding front timing chain case from front and top as shown below.
   3. Same as the previous step, insert dowel pin while holding front timing chain case from front and top completely.

4. Tighten bolts to the specified torque in numerical order as shown below.
   • There are four type of bolts. Refer to the following for locating bolts.

     Bolt position Bolt diameter 

     1 - 5 : 10 mm (0.39 in) 

     6 - 25 : 6 mm (0.24 in) 

     Bolt position Tightening specification 

     1 - 5 : 55.0 N.m (5.6 kg-m, 41 ft-lb) 

     6 - 25 : 12.7 N.m (1.3 kg-m, 9 ft-lb)

1. Install crankshaft pulley, taking care not to damage front oil seal.
   • When press-fitting crankshaft pulley with plastic hammer, tap on its center portion (not circumference).
2. Tighten crankshaft pulley bolt in two steps.

   Step 1: 44.1 N.m (4.5 kg-m, 33 ft-lb) 

   Step 2: 84° - 90° degrees clockwise 

3. Remove Tool.
