So you have a leaking counter shaft seal…

If you ride a newer KTM, especially a newer 4 stroke, you’ve inevitably had a countershaft seal go bad and leak oil all over your cases. Unfortunatly it doesn’t work very well as an auto chain lubing device, otherwise we might just leave it! The problem arises when the belleville washer looses it’s spring and removes the clamping force on the inner seals. The other cause is that over time, the inner steel sleeve builds grooves because of the seal. You’ll want to replace this entire assembly (washer, seal, o-ring and sleeve) every time you do this service.

To do a counter shaft seal replacement, you’ll need:

• The new seals, o-ring and sleeve
• Vise grips
• Picks – straight and 90 degree
• Sockets – 8mm, 17mm and one large enough for the seal diameter
• Mallet
• Drywall screw
• Phillips head screwdriver

Now that you have all the tools together, watch the video as Rob talks you through how to do that counter shaft seal replacement.
