Then use locking pliers to pull on screw head and remove seal
Seal should come out fairly easy
Inspect countershaft splines for wear. This one shows some wear, but should have plenty of life left.
Install new seal. I use a brass drift to gently tap it into place
Slide new o-ring on shaft and then spacer over it. O-ring fits into groove in spacer.
Use contact cleaner to remove old thread locker from threads. I run the bolt in once to chase the threads then hit with compressed air to dry.
Install new bolt, washer and sprocket. The washer sets on shoulder of bolt. Make sure not to crush the washer against the shoulder. If you reuse the old bolt, make sure to use threadlocker.
While frame guard is off, check swingarm pivot nut also.
