Pull your clutch cover off, and pull your outer hub (6 clutch springs and center silver hub). Pull the push shaft out with the torington bearing on it, as well as the long cross over shaft. Then go to the drive side of the motor, and push the rod through. I used a piece of air line to pull the rod on thru the clutch side of the motor. Then re assemble the clutch side, permatex the seal really good, and re-assemble that side too. I had the same thing happen on a 800 mile DRZ2 chain a couple weeks ago, but my seal was fine. Mine trashed the water pump, shift shaft cover, and the c/s cover too. They(EK Chains) are currently trying to work out a warranty for me, supposedly.
