Thanks Brewski.I actually took the encoder from the right side and
exchanged it with the one from the left side.
Strangely we observed that the lift accelerated equally with both wheels.the operator told me later that the lift worked well for several hours then went back to having one wheel moving very slow compared to the other.I have not checked it out as yet, but will update my info when I do. Could it still be the encoder?
