6. Engine Installation
6.1. Installing
●
The center alignment of engine and Generator set is the most important factor for the extension of
performance and life. Although aligning the center perfectly and accurately requires only few minutes,
it is able to prevent unnecessary mechanical trouble at the future.
6.1.1. Bed rail
●
At the installation of Generator set's bed
rail, use steel.
●
If the bed rail is strong enough, the center
alignment of engine with Generator gets
worse so that the excessive vibration may
occur.
6.1.2. Supporting
●
As in the engine installation, the supporting brackets are used even at the installation of Generator.
●
The bracket must be solidly fixed at the Generator installing platform and the bed rail.
6.1.3. Aligning center
●
The center alignment of engine and Generator is the most important factor for the extension of life
cycle.
●
Output shaft flange and opponent side flange of Generator should be aligned in their centers hori-
zontal and parallel direction.
●
The adjustment between flange surfaces at the lower part should maintain less than 0.15 mm when
the upper part's surfaces just meet and the deviation around the circumference should be main-
tained within 0.1 mm as following figure.
●
For bed rail is apt to deform for 6 months after initial performance, adjusting the center should be
checked after 1 ~ 2 months.
