Hydraulic problem jinma 224

[jaroban]

I have changed the o rings on the main hydraulic piston on my tractor before. The problem was I lifted an implement to high. This time I did not lift anything to high or lift too heavy of a load.

Has anyone replaced the seals ( o rings ) without removing the "power lift case box" ?
Can you remove the cylinder cap and simply pull the piston out to replace the seals?
Thanks Robby

I thought that I should add that the problem is when I lift the 3 point it falls as soon as I let off of the leaver. I can lift it again but it will fall back as soon as I let off of the leaver. Robby

On the 200 Jinma (without position control) you can pull the piston out the back of the lift box without removing the lift box. remove the bolts that hold the bracket that holds the top link to the lift box. If your tractor is a 300 series or possibly a newer 200 series with position control (move the lever a little and the lift raises or lowers a little as opposed to the momentary lever that lifts while you hold it and stops when you release it). you probably have to remove the lift box to service the cylinder.

Blue chip you used a term (position control) that is new to .Thanks that is a good addition to the hydraulics. Thanks Robby

Like Chip said on most you can, I would also check to make sure the Stop pin which is on the rear cover has not broken off,that can allow the piston to come out too far too
