If it is a hg 42 motor it should be a hercules ixb engine the made about 18 hp. I had to sleeve my block because the previous owner ran the machine into the dirt. Sleeves where $125 each installed. I spend something around $1800 to rebuild my engine. Yours may not be as bad. Parts are available. Where are you located I may be interested in a dozer blade set up. I am in Northern New Jersey. Good luck with what ever you decide. Jeremy
