(1) Centering method
1. Mount the brackets on the engine secured to the generator main unit.
(Use only genuine fastening bolts.)
2. Place four assembly level plates ※ on the points for mounting the engine and the generator
main unit onto the frame.
3. Place the generator main unit with the engine mounted onto it on the assembly level plates
on the frame.
4. Use shims for adjustment if joint gaps are found at any of the four places where the brackets
and assembly level plates are to be fixed.
5. Lift the engine mounted onto the generator main unit, leaving the shims in the four places
after adjustment.
6. Remove the assembly level plates and place the cushion rubbers in their respective places on
the frame.
(Insert or place adjusting shims on the vibration isolator rubber of both engine and generator
main unit.)
7. Place the engine with the generator main unit on the cushion rubbers and fasten it with nuts.
(Placing vibration isolator rubber for SDG25S,65S, make sure to put plain washers on the
rubber. If not, the vibration isolator rubber is left loose. So vibration could damage vibration
isolator rubber and machine.)
8. Make sure to coat the bolts with anti-corrosion agent “ Metal Clear” which are tightened for
vibration isolators. ( 8 points consisting of upper side 4 pieces and under side 4 pieces.)
※
Before installing vibration isolators, place assembly level plate on the position of generator main unit and
engine connection and then adjust the clearance between engine mounting bracket and assembly level
plate.
