I believe it’s the hydraulic head. I’ve read the tolerances are so tight that if you hold the quill shaft in your fist for 10 seconds it shouldn’t even fit back into the head. Mine did with almost no hesitation and I clearly remember seeing swirl wear marks on the quill shaft. I will confirm this later by running thicker fuel like waste oil. The thicker fuel raises injection pressure in a worn head masking the problem.
Does anyone have a good used hydraulic head for sale?
