Possibly.. you might get lucky,,, but, usually easier to move the motor.
You're going to need to check alignment anyway.

I always leave the motor in place, you should always align after. Make sure you dont drop out the the thrust washers on the crank when you pull the seal.

I doubt you have to move the motor - but if you do, and the alignment is good now, I would loosen the rear endbell and move the rotor back to get clearance for the seal replacement. Just leave the motor base bolted in place.

Neat trick, PHM. Have you had success using this on other coupled motors, like pumps?

It started when the friggin motor shop guys / millwrights would pull the drive motors for bearing replacement and then I would be left doing an all-day alignment. I started changing the bearings myself without removing the motor and so saving all or most of the realignment.

In fact; before he changes the seal on this machine he should listen to the bearings with a stethoscope and change them too if they are at all noisy. While his hands are already dirty and all that. The bearings will "hum" if they are OK and rumble and grumble if they are getting tired. This is exactly why everyone needs to listen to known-good bearings - so they know the difference.

I like to change couplings without moving the motor, when there is enough of a gap between the shafts. Now I know what I can do when the gap is too small. The funny thing is, I've changed bearings in place, too. I just never thought to use one procedure to help me do the other. Thanks for the tip.

Thanks,I finished the job and didnt have to move the motor,P.H.M. i like the idea of moving the endbell to avoid realingment.
