how do you know which engine is in a 4010 lp tractor.340,302,or a 362.Also is the bore and stroke the same?I am going to overhaul the engine and need the information before i order parts. thanks for any help you can give me.
No telling what is in it now, it's been 50 years and a lot of them have been "improved" or "Farmerized", unless you've known the tractor since day one I wouldn't count on it being factory stock. If it's been rebuilt there is a chance that the bore has changed and how do you know what size crank bearings to get. Is the crank still round? has it been turned already? How Much? This is not meant to criticize, it's hurts the hobby when people spend money on a tractor and don't get good value for their dollar. This happens when new bearings are installed on a crank that isn't round and the rebuild has oil pressure problems.
