Hi,
I'm going to load up a break down for you and try to help you,
I don't know if anybody will get to you quickly.

That part number didn't show but this should be the same.

Are you having trouble getting the head out?

Hi,
Did you get number 10 and 13 off.

Steve

Hi,
Those seals should be inside the head, try tapping the head down into
the cylinder.

Steve

Is there any way you can upload an image for me.

Hi,
Number 10 looks like an internal snap ring, that looks to me as to what is
holding it in.

I've done plenty of cylinders, the parts break down is not good enough for me to tell what is going on.

That is why I asked for an image before telling you to tap on the head more.

Are you sure you can't see it, look for 2 points that are near the wall of the inside of the cylinder.

Hi,
You just have to use a flat screw driver, put it in the area behind the point and yurn the screw driver.
You see it move when you do that, than can be a pain in the you know what sometimes.

Steve

Hi,
Have to sign off for the night.

If your having alot of trouble getting that ring out, turn and pry on one side and
you will see more of the ring and a gap, stick a smaller screw driver in the gap,
you kinda have to walk it out like you would when changing a bicycle tire.

After that you should be able to pull on the ram and everything should come out.

Take the nut off the bottom and you can change the packing.

You have to change everything exactly the same as they were, the lips on seals
all have to point the same way you take them off.

If you put any in backwards you'll have a leak and or the cylinder won't work right or
it will stall out the machine.
