Hi guys, What is your experience in dealing with angle/sprung soft foot and these types of shims.Our new Pump Eng.appears to be strongly against the Sof Shoe Shims. From what I heard, they are a good quick fix. Thanks, Manny K

By the way, his choice are some type of Stainless Steel "peel-off" shims. Thanks, Manny K

We have installed Precisionbrand "Sof' Shoe" plastic shims on 6 or 7 motors over a period of about 7 years.

In all cases these were 2-pole motors with 2*LF vibration which was demonstrated to be foot-related (changed substantially during foot loosening) and which we couldn't get rid of any other way.

In some cases it took about 2 weeks to see full decrease in vibration. In all cases the vibration is substantially reduced and hasn't come back. We also have no shifting of alignment that we have detected.

Consideration is, IMHO: Soft Shoe works great but with limitations of time restraint - ergo, cure time. The elastomer hardens under pressuer and compresses ~12%. YOu should install the sofshoe and leave in compressed state for a number of hours (min 3) and finialize the alignment process. Then re-check 3 days later and adjust as necessary.

Costly critical machine: measure and mill a wedge shim if you need something immediately. Sometimes you can't wait on cure time.

Thanks guys, I know that the cure time (approx. 2 weeks)is one of the "con's" however, I remember reading that it doesn't prevent you from starting the equipment. Do you know if everything is a waste when the equipment is stated for testing before the "cure time"?
Thanks Manny K

You don't have to let the equipment set before you start it. But it may be 2 weeks before you see the reduction in vibration.

We had one case (our closed loop #13 motor) where we initially saw no improvement. Then our next check 2 weeks later the 2*LF had dropped to half and it stayed there. In most other cases we saw an immediate improvement.
