I have overhauled my counterbalance hydraulic piston by replacing the seals.
Please can anyone check in my second picture if I have routed the hydraulic hose correctly. (The second photo was taken standing at the back of the machine.) This is very important. I need this information please.
Is there is anything I need to be aware of before I start charging it??? (I.e. before I open the valve on my charging bottle and start pressurizing.)
Over the past days I have replaced the seals in the hydraulic piston, reassembled it, and filled the pressure bottle with 2 quarts of the correct oil.
The piston cylinder is properly seated in its recess and the two nuts and washer are screwed on.
I let in a tiny amount of gas and I could hear the hydraulic fluid bubbling inside. This seems correct to me.
I assume that as I let more gas in I am going to hear a thud as the piston contracts causing the nuts and washer to seat against the head.
I plan to fill it to 100 psi to start, then check for leaks, then fill some more.
The instructions say to fill to 790psi at the bottom of travel, and not to turn on power until it is full charged.
