1. 操作员在安装马达时不能一次性完成，因为需要紧固两颗不同的螺丝。
The mechanic cannot get the motor installed in one attempt, because it has to be fastened with two different-sized screws.
【译注：操作员应该是一个机械师（mechanic），而不是一般的操控机器的人（operator）；两颗不同的螺丝，应该是两颗型号不同的螺丝（two different-sized screws）】
2. 如果将螺丝更换成两颗一样的螺丝，那样操作更加方便，并且不会影响马达张力的调试。
Substitution of the screws with two the same size would facilitate the installation, and would not affect the tension test.
【译注：两颗一样的螺丝，应该是型号或大小一样的螺丝，所以是two screws the same size。翻译成英文时承前省略screws。此外，在没有确凿证据的情况下，用would （而不是will）显得更委婉，使得建议更客气。】
3. 建议更换成一样的两颗螺丝。
It is suggested that the screws be substituted with two the same size.

你好，很高兴为你解答。
保证正确率~！
正确答案是：
1、操作员在安装马达是不能一次性完成，因为需要紧固两颗不同的螺丝.
The operators cannot equip machines with motors at a time , because there are two different screws that need tightly fixing / to be tightly fixed
2、如果将螺丝更换成两颗一样的螺丝，那样操作更加方便，并且不会影响马达张力的调试。
If you exchange the screws into two same ones , then you will be able to operate on it more flexibly.
That won't affect the result of tension test.
3、建议更换成一样的两颗螺丝.
You'd better change the screws into two same ones.
或者 We suggest / advise two same screws be used.
支持原创，(*^__^*) 嘻嘻~~
望采纳，祝开心~！！！

1,操作员在安装马达是不能一次性完成，因为需要紧固两颗不同的螺丝.
Operate cannot install the motor for one time, as two different screws need to be fixed
2,如果将螺丝更换成两颗一样的螺丝，那样操作更加方便，并且不会影响马达张力的调试
If current two different screws can be replaced by two same ones, the manipulation could be more convenient, and also won't impact the debugging of motor's tension
3，建议更换成一样的两颗螺丝.
We suggest two same screws be used
