The exact torque specifications are not easy to find for Hinomoto, Kubota, Yanmar, Shibaura, Mitsubishi or Iseki engines.
This short article is about Mitsubishi and Toyosa(Hinomoto) engines with the exact number of newtonmeters(NM) for tightening headbolts, adjusting valves and connecting rod bolts. Finding the right parts is made easy by Shop4trac. However, it remains difficult to get the right information. This can be found in workshop manuals and/or work instructions if these are still available. Partly because of this we thought it wise to post this article in order to have our cylinder heads and head gaskets mounted as well as possible.
