This is the second time.
That lock on the nut for counter balancer shaft, I forgot it too, but I was still looking at it so no need to remove stuff to fix it.
At least I remembered it, so it doesn't back off 100 miles from home.
If yours isn't leaking I wouldn't tear it down either.
Did you leave the old on the cylinder maybe?
IT might need needed replacing.
