So I picked up a 50C and am doing a full service to it now. My problem is the original owner- a landscape company- had an outside company routinely service all his machines (Not all Deere's). I found recent dates on all filters and the machine is in excellent operational condition so I know it's been maintined BUT- he's convinced they've been using 32 weight Hydraulic oil.
I've asked enough different ways that I'm starting to sound annoying but- my understanding is that Hitachi/Deere spec AW46 zinc free? He's knows its not Deere oil. He doesn't know if the oil is zinc free, he's pretty sure it was synthetic and almost positive it is 32 - and not 46 weight.
Looking for some ideas on how to best proceed at this poing and not make create problems?
I'm thinnking of draining the tank and adding 5 gallons of the correct oil. Cycling all actuators several times- then draining the oil again. chnage the filter and fill to capacity with correct oil?
Opinions?
