I've got a D7E 48A 68XX . Old girl just started giving me trouble with the blade. When I lift the blade up and put it in hold position, one corner instantly drops. So for some reason the one hyd cylinder isn't holding. When I put down pressure on the blade all is fine. Is the issue more likely in the cylinder or the spool inside the tank ? The blade corner drops so fast I don't think it's the seal inside the cylinder.
I think it has to be the cylinder. If it was the control inside the tank both cylinders would be dropping when you release the blade control lever.
Sounds like nut is loose on rod
Ok, boy over the years I've had plenty of cylinders leak off but this one acts like nothing I've run into before! I'll pull the cylinder and see what I see. Appreciate the input!
If it’s the nut, be prepared for an expensive fix!
