I sure could use some help with a Hydraulic cylinder.

I have a New Holland 757C back hoe attachment for my New Holland 1920 tractor.

One of the stabilizer support hydraulic rams is leaking bad so I bought the kit to rebuild it ($100 :-( )

How the heck to you get the end cap off of one of these cylinders?  It turns and turns but never comes out.  I can's see a snap ring any where.  Something has to be retaining the end but heck if I can find it.

Anyone have experience with these cylinders?

Looks like there's a pin you knock out & then you spin the shaft to unthread it from the bottom of the cylinder. Probably easier if you leave the lower end connected to the stabilizer to hold it.

My end cap does not have holes to spin it, there is no pin.  I can't find any videos that show what I have and how to remove the end cap.  I have spun it many times and it just turns.  It is not threaded like the others I have seen on youtube.

Some cylinders have a lock ring that is inserted by spinning the en d cap. It is then removed by turning the end cap the other direction. However sometimes the lip gets broken off and the lock ring is stuck inside the end cap. Then the fun begins. Don

I found it, or actually a friend did, he has a flexible neck.  There is a clip down on the barrel of the cylinder that hold the end cap on.  Now onto rebuilding it.
