| Just put any cylinder that will fit on it. All the talk about a high pressure cylinder is 100% "BS". Have done it for years with no problems. |

| Well, in defense of the hydraulic cylinder builders, back in the days of AC high pressure system (3400 to 3700 psi), an "M" Farmall was I believe only 1,000 psi, so he&& yes, there was a difference in them. But, today's modern cylinders are far better than that. If you are a sharp operator, you can tell when the disc is almost to the top and just return the lift/lower lever to hold. It will only spike at high pressure when it hits the top and then a couple seconds later. |

re: All the talk about a high pressure cylinder is 100% "BS". Have done it for years with no problems. kinda like playing Russin Roulette....... A good 1000PSI cylinder will be tested at 3000# ( typically 3x the rated normal pressure), same as air tanks ( 300# tank, tested at 900# ) plumb a worn 1000# cylinder to a real good 3800PSI pump... cycle it a few times... it'll blow, eventually, same as Russian Roulette.. a 1500# cylinder would be burst tested at 4500#....maybe.... and just WHERE was the cylinder made ??? ------------- 3 D-14s,A-C forklift, B-112 Kubota BX23S lil' TOOT( The Other Orange Tractor) Never burn your bridges, unless you can walk on water |

| Your big bolted together cylinders will be slow to lift plus after using for a while. It will stretch the bolts to where it will blow end seals. MACK |

I have some used Factory high pressure AC cylinders available. One of them is a 2 way. You can email me directly at: the1orangewizard@gmail.com
 ------------- If it was fun to pull in LOW gear, I could have a John Deere. Real pullers don't have speed limits. If you can't make it GO... make it SHINY |

How do you tell a high pressure cylinder from a low pressure one? ------------- Do not argue with an idiot. He will drag you down to his level and beat you with experience. Mark Twain. |

you'd hope the cylinder has some kind of MFRs part number on it..... BTW a couple hydraulic sites say the burst ( test) pressure is 4X !! not the 3X I was lead to believe.... so a 1000# cylinder 'shouldn't ' fail at 4000PSI which is more than most A-C pumps put out... ------------- 3 D-14s,A-C forklift, B-112 Kubota BX23S lil' TOOT( The Other Orange Tractor) Never burn your bridges, unless you can walk on water |

Where are you at in Ohio? I'll check, I might have one. ------------- Life is simpler when you plow around the stump. |

A "worn" cylinder??? About the only thing I ever saw worn was the seals, ….which BTW would bleed a little pressure! LOL I've got cylinders around the farm that are probably 60 years old. I did have an old cast iron cylinder split LENGTHWISE when the tail wheel of a plow slammed over a rock or something. Didn't know it until the end of the row when the plow wouldn't lift and oil sprayed all over the back of the tractor. |

| Official A-C high pressure cylinders are never larger than 2 inch in bore diameter. In fact, I think 1 3/4" is the largest I remember. |

| Allis hi pressure cyl are "skinny "compared to anything else. I know they made 2 different diameters. I have a couple of each but don't know diameters. |
