When the Mounting plate(F) and the Engine mount are detached and are attached again, follow the
procedures below to avoid giving uneven tension to the Reinforcement beams.
1. Loosen the two bolts, which are connecting the Generator mount and the Engine crankcase to make it
possible to move the Generator mount. Keep them loose until the following Step 6.
2. Tighten the 4 bolts (M4 x 10) on the rear of the Reinforcement beams if you loosened them. It is
difficult to tighten them later in the process. Tighten the 4 bolts on the front of the reinforcement beams
temporarily so that the Reinforcement beam and the front bolt does not turn together when you tighten
the rear bolt.
3. Loosen the four bolts (M4 x 15) temporarily, which are fixing the Reinforcement beams from the front.
4. Tighten the four bolts (M5 x 20) to fix the engine to the mount.
5. Tighten the 4 bolts on the front of the Reinforcement beams again. Tighten them even if you are going
to mount the Generator later on.
6. Tighten the 2 bolts loosened in the above Step 2.
7. Connect the Manifold pressure tube.
8. Follow the procedure in Page 13-14 When you mount the Generator.
