Ahh I see.... no thats not good, If you're just replacing the bushes you don't need to adjust anything
If you want to check the adjustment get yourself an old cassette box (slimline TDK's work best) and wedge it into the gap, it should be a perfect fit - and thats it, job done
(if you don't know what the "gap" is you're gonna have to get a manual and check cos i cant describe it
)
