                                                       <Connecting Rod Cap Bolt Installation>

                                                       1. Check the connecting rod bolts using the following
                                                       procedure before installation:
                                                       (1) Measure the outside diameter "A."
                                                       (2) Measure the smallest outside diameter "B" within the
                                                       range "X" shown in the illustration.
                                                       (3) If the difference of outside diameter of thread ex-
                                                       ceeds the limit, replace the connecting rod bolt.
                                                       Limit: 0.1 mm

                           Fig. 5-31                   2. Apply engine oil to the threaded portion and the seat
                                                       surface of the bolt before installing it.

                                                       3. After installing each bolt and tightening it by fingers,
                                                       tighten bolts alternately to properly assemble the cap.

                                                       4. Tighten the bolt in several steps until the torque
                                                       reaches 5.0 Nm.

                                                       5. Tighten the bolt in several steps until the torque
                                                       reaches 20 Nm.
