Thank you very much Jeff for bring this subject up.
Without the hydraulic effect our engines would not last very long.
But theres always a but most of the time its me
Questions
1 how much of the load is spread where on the rod?
2 Where does the rotating mass separate from the reciprocating on the rod?
Weighted a rotary rotor today only one.. with parts missing would you believe 5300 grams I'm no Mazda expert but I believe theres needle bgrs available.. eyeballing the journal 2.5 inches
Sorry Bob for highjacking the thread
