I hope someone can help me. I broke a connecting rod in my JD318. It has an Onan P218G motor. I need to know what the torque specs would be for the connecting rod and the head bolts.

I think it should be 159 inch pounds +/- 9 inch pounds.

I made the same mistake when I first looked at the specs that were in my service manual.

Here is what my manual says.
