I have an Encore 36 walk behind with a Kawasaki FC420V. Its probably got a good 2500 hrs on it. Unfortunately its run its course and I need to replace it. Basically I noticed small amounts of oil on my shop floor where it was parked and as time went by the amounts of oil got larger. One day while mowing I stopped to pick up some trash and looked at the front of the motor. I noticed oil spraying out where it attaches to the deck. I thought it might be a gasket so I took it up to my mechanic. He told me what he thought it was ( I dont remember) and quoted me $1300.00 to rebuild the motor. After some research I found some online distributors that have motors in the $700-950 range. My questions are this: I see that the FC420 is no longer available. What is a comprable replacement from Kawasaki for it? As far as replacing. Im a halfway decent mechanic. I can replace the belts and adjust the hydros, stuff like that. How does one go about doing this? I noticed it has 4 bolts. Do I just remove those bolts, lift the motor off and put the new on? Im pretty tight with my money so I would rather do this myself. Thanks.
