I posted this in Parts/ and Repairs but figured I post it here in the Kubota section too.


So I changed out the head gasket on my b7100. Getting everything back together and need to adjust the valve clearance. Hope I’m getting all the terminally right. I understand how to actually adjust them with the feeler gauge. What I’m having a hard time with is understanding where to start. What cylinders are ? ? and ?? The manual says to adjust them in their injection order 1->2->3. Im not really sure I understand what the injection order means? How to know when and what piston is raised ect?
If I’m at the front of the tractor I will number the valve springs in order from 1-2-3-4-5-6. When 1 is compressed so is 6 and then when I turn the crankshaft (?) counter clockwise 4 and 5 will compressor and as I turn it again 2 and 3 will compress. If when 1 and 6 are compressed, what two do I adjust? If 4 and 5 are compressed, then what two do I adjust. And lastly if 2 and 3 are compressed what two do I adjust?
I watched what I could on YouTube but they don’t have a lot on 3 cylinders. Not any that were clear enough for me to understand anyways.
Any help would be great. This is all I have left before I see how I did on changing the head gasket. Almost time to fire her up.
