For owners of 565,665 ,ls160 and 170 new Holland this is the link to a service manual that is well worth the time to download and save. It is for the 160 and 170 but the covers the 565 and 665 to a large degree. I use it for the 665 and have found only a couple differences. http://www.mediafire.com/?ux89bq2u4u3ug
