Mine was doing that when I got it. Took the cylinder apart and the cap screw was loose tighten the screw put it back together filled with oil and still works great.

I'm sorry cap screw was loose on the piston. I get ahead of myself sometimes sorry.

This is a picture of the cylinder. The small brass valve on the top is what controls the rate of feed. The red handle allows it to drop or holds it up. I tightened all of the connections and it still does not work. How do Iknow if it is low on fluid and if low how do I add fluid.

Thanks Jay

 

If you shut the ball valve does the saw come down

 

Yes -

 

if it comes down with ball valve closed (those are pretty reliable in "not steam" applications)

your leak is internal, like john was getting at. you should open up the cylinder and take a look

 

X2 internal leak

 

Did this just start?

 

In the last couple of months it had been taking a couple of "pumps" when lifting it up to make it catch, but yesterday it would not catch at all. I will take it apart tonight, but I have never worked on something like this so don't really know what to look for.

You don't realize how much you depend on something until it doesn't work when you need it.

 

My cylinder is leaking too. It still holds, but I'm not sure for how much longer. What are people using for replacement fluid in these?

 

I believe it is 10W non from.

I'm 90% sure you need more fluid or just need to bleed the cylinder. A lot of times those cylinders are self-bleeding so start with adding more fluid. You can buy hydraulic oil at Autozone. This isn't CNC machinery we're talking about, you don't need to worry about matching oils. They sell a fluid literally called "hydraulic oil". Just got to find out where the fill port is.

 

I rebuilt the let down cylinder on my Johnson J model last winter. Just bought a new cup from a cylinder seal shop and refilled with iso 150 oil if I remember correctly is what it called for.

 

Has any oil leaked out

 

Doesn't look like there is any leakage. I did find a good parts diagram and it shows an o ring and oil seal so I ordered both. I think the only way to add oil is to take the connection at the bottom of the cylinder off and put it in there. I will see it adding oil helps tonight, if not the parts should be here early next week. If adding oil helps I will have the seal and o ring when I need them.

 

If no oil leaked out you shouldn't have to add any

 

I use hydraulic jack oil (mineral oil base) in mine. Available at any auto parts or hardware store. It would be a good idea to change the oil when you replace the seals and o'rings. It is very easy to do the repair so don't worry about messing it up. Take your time and protect the rubber parts from nicks. Put a little bit of oil on the seals. You will do fine.
