Bleeding system was my biggest concern making the system work. I spent allot of time testing/bleeding system on bench before I concluded I was going to use the trapped oil steering system on tractor. I had thought out how I was going to bleed system on tractor before I moved system from bench test to tractor because I knew it was going to be a bitch! With that said, I used tee fittings in place

Glen, I see no reason why this system would not work on a 9000# tractor. As you well know, the tractor being heavier will add to steering effort no different than any manual system whether hydraulic or mechanical. The other factors are the mechanical make up front axle and its mechanical efficiency. This includes the steering arm length off spindle center, as well as how far center line of front

To answer your question correctly I would need to know the exact displacement of your steering cylinder you plan on using with this Char-Lynn valve/motor. If using the same cylinder as I used, you are 3.782 times to large/big of displacement on the Char-Lynn unit.(7.3 /1.93=3.782) This would cause tractor to steer very hard! But fast! Do not think you want either. Another factor I would be concer

I would have to go home and count the actual steering wheel turns to be exact but, if my memory is right it was 6.5-7 turns lock to lock and front wheels turn shorter/tighter circle with hydraulic steering than they did with rack and pinion. The rack and pinion ratio was about the same amount of turns but, did not turn as sharp/tight. As noted in other post, mechanical make-up/geometrey also ente

Tractor steers easy in pits and setting still, Much easier compared to the rack in pinion system. With tractor setting still/shut off I can turn steering wheel standing on ground reaching up with one arm an it is easy to turn. Take note our tractor is a 6700# unit., DW

System is a closed loop, trapped oil, manual system. No pressure/supply pump required/used. I have been told a helm system has small reservoir. This system has no reservoir or needs a reservoir because of the balanced cylinder. The return side of steering cylinder is the same volume/displacement as the pressure side and displaces the same amount of oil going out of cylinder as coming in. Oil retu

Hydraulic parts used for WTW manual hydraulic steering system were purchased from Surplus Center. Balanced hydraulic cylinder is 2X8X1.25 DA Double Rod. 2"bore, 8" stroke, 1.25 diameter rod out both ends. Item number 9-6845[. Steering motor used for hand pump is 1.93 cubic inch displacement per revolution and is a Char-Lynn129-0004 Item number 9-1157. The rest of system was 1/4" hydraulic hose, f

A balanced hydraulic cylinder (rod out both ends) and a orbital motor used for the steering valve/pump that I matched its displacement to cylinder volume were both bought out of the same hydraulic surplus catalogue. Steering pump/valve/motor is smaller than a 12 OZ beer can. Steering cylinder and motor parts were both easy to mount to fabricated front axle and steering column. System uses standar

Built my own system from new parts. Works great on 6700# tractor. Two years of use, no problems and never bled it since it was originally installed. Two years ago I had around $500.00 bucks invested in system. Don't know what same parts cost today?? DW

Sir, The fuse blowing is indicating there is a short to ground on one of the 12 volt lines/circuits. Ground one baterry at a time to determine which line is shorted. Most often the short will be found in the starter motor. The starter and generator are NOT grounded to the frame. If a field winding in the starter, starter solenoid, or field winding in the generator is shorted to frame ground,it wi

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 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 fo

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
