Power Steering on D14,,,AGAIN,,,,!!!

   Well,,,,,,,,,,,,,,,,I had to use the D14 yesterday to raise some bundles of shingles to top of house for contractor,,,and the dang PS threw another fit and was not workin for chit. I hate havin to  manhandle the dang steering wheel with BOTH hands especially in this cold weather. This POS PS has been on and off the whole time since I got the tractor goin. 

 As some of ya'll might remember,,I milled the face of the pump to bring it to factory specs and replaced the two shafts that the gears ride on. I have had the pump off (heck of a job!) 3 times to verify everything. I even changed front tires to smooth thread in hopes of reducin the drag and run em at 50#. If you get any kind of load in bucket (4 bundles of shingles) it just will not hardly get out of it's own way.,and THAT is with both hands,,!!

 Has anybody managed to "Modify" this system to where it is a better workin system,,?? If it wasn't such a great tractor, otherwise,,I'd be pretty dang tempted to trade it for another brand or something,,,,,!!!  (even a John Deere,,,!!!

 Hey Mack,,many thanks for the comeback,,,A little history of my tractor,,,

  yes,,when I first started up the tractor after rebuildin the engine,,the PS became a big thorn. I did pull the pump and there was some wear on the shaft of the driven gear,,plus there was some wear on the matching faces of the pump. I had the pump faces milled to proper Gear/Pump ID clearances and built a new shaft on my lathe. I checked the output pressure at the control valve inlet and while I cannot remember exactly what the pressure was,,it was within factory specs,,(got it wrote down somewhere),,,The pressure ring on the ram had good end gap so I re-used it. Both gears inside the pedestal had good tooth contact and adjusted the rack as per book specs. I have cleaned and flushed the complete system TWICE  thinkin some trash be floatin around. When I first started the rebuild,,the PS reservoir was plumb full of dry black sand lookin junk and I decided to completely disassemble the PS system and really think this crap was result of tractor settin for so many years. I believe I got all the junk out but maybe,,,???

  The tractor as a whole showed very little use as it was purchased new by the Interior Dept for The Forest Service and stayed it's whole life at Fort Stanton up in the mountains til it sold at auction but was never rebuilt til I bought it from thet bidder. 

  I have read where some farmers have used a Char-Lynn system mounted on the steering shaft,,,what do you think??  Also,,there was a member here that some time ago,,installed an additional pump above the alternator on a D15 that maybe a promise,,??? 

 I KNOW farmers are the best inovators at makin do and modifyin their equipment to get the job done,,,,so,,,,How bout it all youse Guys,,,??? 

 Yeah,,Steve,,,and,,,,and,,,I was sure hopin NOBODY would even get close to suggestin I remove thet big, heavy, unhandy, unweildly, did I say HEAVY,,,center support,,,???

 But,,,as a fact of the matter,,,I DID already remove it twice ,,,once when I first got the tractor and then again when I had to replace thet big pin that it swivels on the front axle.

 When doin the initial teardown,,is when I found all the old dried up oil residue in the reservoir, I had the whole thing  completely apart and washed inside out real good. I disassembled the cylinder, control valve, both steering gears as I had to replace the btm oil seal on the output shaft. Everything looked and mike'ed out per specs so I lashed it all back up. After checkin the two manuals I had I filled with ATF and system worked with one finger turnin. At THAT point, I did not check pump discharge pressure as no reason to suspect, and loader had not been installed. Boy,,was I headed for a surprise,,,,

 After loader install is when trouble showed up. I then removed the friggin pump and fount the worn shaft on pump gears. Had the pump body milled and replaced the shaft. Then is when I installed a pressure gauge off pump discharge and pressure was within specs and RV did not relieve to bypass any oil. System was still IFFY, so I removed the pump 3 times, I think,, but discharge pressure was OK. Somewhere in thet time frame,,I removed the center support again to replace the big 1 1/8" pin and I flushed it out but system was very clean then. Removed cylinder and inside was also clean and ram sealing ring was ok,

 Mack mentioned something bout an adjustment on the control valve that I was not aware of ,,,and the more I think bout this,,,I'm  thinkin that may be the culprit here,,,??

 I remember some time back,,Dave Kamp talkin bout how the CV is susspossed to operate where something triggers it to supply oil to piston and then to bypass  when toggled back and forth,,,,,HMMmmm Gonna see if I can find the thread I had when doin the rebuild of this tractor,,,,,

 Also, DrAllis mentioned on a D17 thread that current Universal Hydraulic oil was good for those PS systems and am wonderin if OK in the older D14 system,,???

  Sorry for the long winded dis-a-tation,,but my arms still hurt from manhandlin thet steerin wheel 3 days ago,,,,,

  

   Well,,I had to use the loader on the d14 again yesterday and,,,AGAIN,,I had to fight the piss poor steerin on thet son of a gun,,!!  I went ahead and set up the engine puller Gantry, chained up the loader to it and started to remove the Heavy pump guard and Radiator support,,,,and,,,,after lookin at everything that has to be removed to get to the control valve,,,,,I decided right quick that this is prolly a warmer weather job bein as it was 18°,,!! Gonna have to rig up a support for the engine as the front engine support has to be removed to get the valve out ,,,OR,,,remove the whole front assembly,,,!!!! Either way it is a BFG,,!! JEEEZE what a big job. SO,,,after readin some on other posts,,I dumped the ATF and filled the PS with Universal Hydraulic oil ,,,,and,,,dang if it did not work some better,,but without a load. Lashed everything back up and The real repair is gonna have to wait for warmer weather unless somebody comes over and  builds a big shop sometime soon,,,,

 Many THANKS for all the suggestions and support,,,this shall resume long bout ,,,,,,,,April or May,,,,,

 UMMmmmmm,,,well,,I got a bit of an update on the PS issue,,,altho it may not be the best option,,,,,the fact remains,,,,IT WORKS,,,!!!!!

 I took a few looks at the "massive job" to take the whole PS system apart to properly go thru everyrthing and check out all the different components and bein somewhat lazy these days,,,not even considerin how dang COLD it been these last two weeks,,,,I dumped the ATF out  the system and re-filled with some THF,,,seein as how I wanted to go visit Ms Big Ones anyway,,,,,,,and I couldn't believe my tired old arm muscles,,,!!!  I mean,,it ain't one finger easy but I can now turn it (with some dirt in bucket) with just one hand,,,Gosh I'm so glad,,thinkin I'll prolly keep this old tractor now!! 

  I wouldn't think the Hydraulic oil will harm the system so the teardown can wait till warmer weather,,,but,,,I'm sure wantin to leave it as is,,it works so good,,!!!
