Rack & Pinion Vs Hydraulic Steering Opinion

I have read the different post. Has anyone regret going to the Hydraulic(Helm Pump)? I need to replace my rack &pinion steering and not sure which way to go. How hard is it to bleed the hydraulic set up? Thanks for your opinions |

I have a helm pump steerinf, not totally happy, if doing it over, would put on 12v pump and and run power steering.....Question for anyone out there, can you put pressure to a helm pump and make it power steering? heard something about that somewhere, then it slows steering down when on the track if turn pump off. |

I got hammered on the other post for trying to help somebody. The helm pumps work too slow for some people. Takes too many turns lock to lock. Your junk yard setups won't work without a pump. Most people don't want a pulley driven pump' The setup I talked about will work with the pump on or off. It steers just like factory steering with the added benefit of no mechanical linkage like a rack. This very nice to install in tight spaces. It is just a matter of how nice an install you want and how you want it to work. Good luck and if you need any help, just ask. PS Still not afraid to sign my name. |

Richard, I did read your post an I have considered that setup. But the issue I have is I don't have an alternator so I don't want to kill the battery. That's why I'm back to the rack and pinion or helm pump option. |

I don't run an alternator either. I have 2 group 32 batteries 800 CCA. I normally charge them before every pull. Just for kicks I didn't charge them for 3 pulls and couldn't tell any difference. The pump doesn't use much power. |

put a seastar power assist to it when you go to steer it kicks in buy them on ebay |

What does that power assist do, do you plumb it into the other two ports on the back of the helm pump, wouldn't any 12v hyd pump work. them things are pretty expensive |

yes it does . it runs on 12 volt and only runs when you turn the wheel |

but would a 12v pump with its own tank work plumbed into the other two ports and put it on a switch and just use for around the pits? |

could you tell us a little more on what parts you used? |

I used a balanced steering cylinder (rod out each end). Determined the displacement of cylinder and matched a compact orbital motor with correct displacement that would give the desired steering ratio. Motor is the steering valve. Eight turns lock to lock, tractor turns easy and short. Mounted motor to steering shaft making a coupler and adaptor plate. Mounted cylinder to front axle using the four 3/8”bolt holes that were in cylinder. Steering cylinder being balanced and sealed does not require a reservoir. Return side of cylinder is the reservoir. Connected motor to cylinder with ¼” single braid hose and fittings. Trick is bleeding it. Takes about five minutes to bleed with required tools. I bled it in late June and have not touched it since. Went on and off the truck and down the track approx.. 20 plus times this last summer. The best part was the compact steering motor as it is smaller than a beer can and allowed me to put it in the original location and maintain full function of the telescope and tilt wheel features. Don’t need to take my steering wheel off to get out of cage just throw it up out of the way. DW |

You said your tractor weighted 6700#. Would it work on a tractor weighting 9000#?? |

I am sure it would function the same but, would expect the steering effort to be greater with the extra weight. Even though it is hydraulic it is still manual! |

I love the hydraulic helm pump and double cylinder setup. Tried a couple other attempts at hydraulic options and rack hard to turn, possibly a too fast of turning
ratio. helm pump has it's own reservoir in the pump, so it bleeds itself, when turning. all links are listed under rack and pinion heading on forum page. |

Bear,
I built my own trapped oil hydraulic steering system for less than half of what the helms set up cost. The trick to making it work was bleeding it. Took me less than 5 minute to bleed after I figured out how I wanted to do it. Steering system works very well and steers easy. Ran full season never had any problems and never had to bleed it again. Only thing I found out about this set up is when I went to get my tractor out of cold storage to put in heated shop system was lazy in below freezing temperatures. Once in shop and warmed up it was right back to itself working like it did all summer. Components used to build this system are off the shelf parts and did not have to modify either cylinder or control valve. Steering valve/ unit is smaller than a 12 oz. beer can. I used 1/4” lines between cylinder and control unit. This system is on a 6700 # JD tractor with full functioning tilt and telescoping features. |

So which is the best Helm pump set up to use? How is the best way to set it up? |

Ross, what setup do you have on your super farm ? |
