Small Engines (Lawn Mowers, etc.): Honda Oil leak bottom, crankshaft seal, honda lawn

Question
Hello, I have 10 year old Honda Lawn mower 21", aluminum deck with a GXV140 engine.  I was running it and suddenly heard a loud pinging, I then stopped the motor and checked the dipstick.  It was emtpy with a small stream of smoke coming out.  The oil was leaking all over the blades on the bottom, but nothing on the top.  I am guessing it is a crankshaft seal.  It has the roto stop.  Does this sound like the right seal to you?  What is the best way to replace?

Answer
Hello Steve:

The Lower Crankshaft Seal is the One Leaking. You can View a Breakdown/IPL of the Mower/Engine at this Site Addy, http://hayward.arinet.com/scripts/EmpartISAPI.dll?MF&app=ASP&lang=EN&TF=Mainfram... and Select the Catalog American Honda. Remove the Components from the Crankshaft and Using a Screwdriver, Carefully POP the Oil Seal Out. Then Using a Deep Well Socket or Piece of Pipe Tap the New Seal into Place. Before Replacing the Old Seal; Turn the Engine by Hand and Watch the Crankshaft Center Hole. If it Wobbles, then the Crankshaft is Bent and Replacing the Old Seal May Cure the Oil Leak Problem for a Short Time Only. The Solution for the Bent Crankshaft is; 1- Need to be Replaced. 2- Straightened. 3- Replace the Engine. Hope this Helps. I am Here if You Require More Assistance. Let me Know What Happens, Please. Thanks.

Good Luck
