It likely will have no effect on anything.  Like Roger
said, backlash is a function of friction, properly
maintained that coupler should give no problems.  If
you want to improve its operation the best move would
be to take out any mis-alignment by shimming the PTO
mounts so that the shafts are as close to parallel as
possible, then the Oldham coupler is basically out of
the equation as it's only function is to make up for
sloppiness in the shaft alignment.  

Backlash isn't a problem there as much as binding is.

Even if the coupler sections are excessively worn the
spring will take out any backlash IF there is no
friction on the PTO shaft.

Don't forget to loosen the bushing on the front panel,
under the KC CHANGE knob, it should be only snug.
