I've been a forklift mechanic for many years and it is probably the piston seal in one of the tilt cylinders. If you can cap off the cylinders individually just cap one side off and see if it bleeds down if not it is the other side

I have not had a chance to work on it, but im going to check the tilt cylinders. i assume it has two sets of seals inside since its dual acting? I replaced the seal in the main cylinder years ago, so should be similar?

It will have some type of seal on the piston depending on how old the forklift is and a seal on the gland end of the cylinder. Very easy to replace and can be done without even removing the cylinder from the machine.

I have been using it for about 8 years and it always keeps going, just needs a little push every now and then. i finally got tired of the generator not charging and no power steering, so i took the factory stuff off and put a gm power steering pump and 3 wire gm alternator. Its ugly but works and makes me money.
If anyone has a picture of what the cylinder looks like apart that would be awesome! Should the hydraulic shop have the seals for it, Is it common for them to be a stockable seal and not a special order thing? Its been about 5 years since i rebuilt the main cylinder and i really dont remeber doing anything but knocking that nut off the top, pulling the shaft, taking it to the hydraulic shop and they slid on a big seal and i put it back together. should be the same except it will have two seals on the double action tilt cylinder? Thanks so much
