Generator Coupling

[Sajid khan]

We have ordered a 150kVA prime rated generator. The generator is coupled by vendor on his own workshop. The engine is Perkins and alternator is leroy somer. The workshop of the vendor is'nt so big and i think they dont have much capability and precise tools for coupling.
I dont have any experience how to check coupling of generator..
What are the disadvantages of having improper coupling?

Keep in mind this is a NEC forum.
but improper alignment of generator be similar to a motor, vibration and bearing damage.

Sorry what I meant is this entire forum is related to the NEC. I would not expect a lot of answers on your post. A motor shop would have the necessary alignment tools.
