Oil Seal Around Srocket Shaft

[pete fry]

My oil seal is leaking around the sprocket output shaft from the gearbox.Is it just a straight forward swap??? :ride:

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.

Thanyou,I have just checked and there is sprocket movement so I will sort that.

oil leak around srpocket

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
