Hyundai Repair: 1986 Hyundai Excel GLs 4 plugs, crank pulley, hyundai excel

Question
How do we change the bearing on the bottom pully, if there is one. I have a oil leak from this area and want to know how to fix it.

Answer
There is a seal behind the crankshaft sprocket.  You'll need to remove the timing belt (requires removal of crank pulley, water pump pulley, timing covers) to get the sprocket off.  Once you have the sprocket off, you can pry out the old seal and install a new one.
