bulldog7 I've got a 1610D and I don't think you can get one in english.I bought one for a YM226D which I was told is the U.S. model and is close to the 1610D.I've been able to take the head off using this manuel.the torque specs. etc. are all the same.I also have a parts c.d. for a 1610D, some of it in english some in jap. but i've been able to get parts # of the jap. part, I got the manuel from Town and Country Tractors inc .the c.d. I got from Little Miami Trading Co. hope this helps russ
