I have finally pulled the motor and removed the flywheel to access the ring gear on the new Vanguard that i installed two years ago. Have about 80 hours on the motor when the starter hung up and shredded the teeth on the aluminum ring gear. Engine is a 294447-0445-01 18 Hp Vanguard. Looking up a replacement gear shows no longer available. Any suggestions on a replacement gear. Hard to believe that a 2 year old engine is discontinued. Was hoping to find a steel ring gear since the steel pinion gear really destroyed the aluminum ring. Thanks
