Question

Answer
Duane,
 If it ia a "top to bottom" split you need to remove the bolts from the underside w/ an impact hammer, there should be 10 or so.  Then carefully pry them apart making sure not to damage the mating flanges.  You''l then need to clean the surfaces before reassembly and apply "Three Bond non-hardening sealant.  "Side to side" is the same principal just that the bolts are on one or both SIDES of the engine.  For both senarios the case must first be removed from the frame.
