If the sprocket is floppy on the shaft, a new seal won't help.
The thx of the sprocket is critical to compress the o-ring, seated within the bevel on the spacer, which should be facing inward. Check that before changing seals.
so when you remove the old oring and replace it with a new one the sprocket should have little or no play,but wouldnt that cause the spacer to cut into the fresh oring while it turns???Just want to make sure i do this right! I have a 06 Suzuki RM250Z is it the seal i need to replace or is it the oring,does it have both??? Thanks
