You can't get to the seal by simply removing the harmonic balancer; the front casing must come off. If you just need a harmonic balancer, just replace that, and don't go cheap. I bought one from Germany just last month for an M113 for $80 which was a waste of money and time. Your best supplier will be needswings. and you will need the right tools. i bought a 40" 3/4 inch breaker bar to torque the new one on.
