Some compressor motors aren't reversible.

More info on the motor would be helpful.

Brand?

Type of starting circuit?

number of capacitors?

Voltage?

..............?

You could modify the mounting so a change of direction wasn't necessary.

You could use the old mounting plate & some brackets to on the new tank.

Usually, compressors have arrows for direction of turn. Follow them first.

You will get more and better answers to your questions if you present your questions in English. Many of us refuse to even read much less answer questions presented as yours is. Leave text-messaging code on your cell phone. It doesn't belong here.

It looks as if you have some good leads so far, so just consider this as a helpful hint for the future.

Sincerely

Bill

I agree: We need more information to work from.

Running the motor backwards does not bother me, as you have seen it will trip the breaker if not wired correctly.

I would be more concerned that the compressor is capable of running in the reversed direction, if not it will self destruct.

I take it that you do not have to be a qualified electrician to tamper with electrical motors, etc., where you come from? Do you by chance happen to live in India?????
