Purchased a motor to replace the old one on my rototiller. It's a fine engine, but sadly they nearly ruined it with their modifications.
Standard practice is to cut a key way to connect the drive shaft to the pulley, however they took a shortcut and simply drilled a tiny hole through the pulley into the drive shaft, and put a itsy bitsy set screw to connect the two. This means that 11hp of torque every time I fire up the motor is transmitted through a 4mm screw instead of a 2.5" key.
You don't have to be an engineer to see how cheap the design is. I took it to 3 mechanics who laughed at the modification, assuring me it will fail, if not right away then within a month or two. Not only that, but there was significant play where the pulley sits on the shaft, way out of spec. I can only assume this company doesn't have the skill or the tools to properly modify these engines and instead took a cheap shortcut at my expense.
Customer service was robotic, even rude, and refused to acknowledge the flaw. After looking them up, discovered they have an F rating with the BBB and terrible reviews online. After spending $100 on a machinist to fix their mistake, I'm up and running and farming again.
