    Hydraulic power steering - centering the steering wheel?

    Fritz, no external leaks but given the tractors age and no sign of the steering cylinder ever having been resealed, I'd say you are spot on. In a tight spot or rapid, slow speed changes in direction, the steering wheel can sometimes turn a bit without the front wheels turning - I had thought it...

    Hydraulic power steering - centering the steering wheel?

    Orbital valve, that's the word I was looking for! Complicated enough to make Rube Goldberg proud. A friend who saw it apart on the bench asked, "who sat down and figured out where the holes needed to be drilled?". Back to your question, it's an 885. Have a 990 yard ornament with the same...

    Hydraulic power steering - centering the steering wheel?

    Just re-sealed the hydraulic steering gizmo at the base of the steering column on my David Brown. While following instructions for bleeding air from the system I found the number of turns to lock varied between left and right turns by more than one revolution. Nothing I tried seemed to make...

    SAE 10W or 20W oil

    Unobtanium? Going in the power steering on an 885 David Brown where "a good 10W oil" is called for. Can't find straight 10 or 20W. This will be a total change-out of the fluid after a repair. Would it be okay to use ISO46 (20W)? I have a fiver on hand. I see claims it work fine in power...

    David Brown 885 Steering Wheel Upper Bearing Leaking Grease??

    The lack of reply suggests this isn't of much interest but, after looking for parts I found others have had the same issue. So, maybe someone might benefit . . . the source of the oil leak is/was the hydraulic steering unit at the bottom of the steering column. A failed internal hydraulic seal...

    885 David Brown with a Danfoss Steering Valve - Reseal Parts

    At the least, the topmost steering seal on the hydraulic steering valve is shot. The valve has filled the steering column with oil making a mess. Danfoss wants right at $100 for a small number (about $5 worth) of o-rings and a seal. Looked on line for alternatives but Danfoss seems to have a...

    Hydraulic Cylinder Question

    In case anyone might be interested - After having used the loader enough to form an opinion after altering the dump cylinder restriction, it is my observation that increasing the area of the restriction by 50% (area, NOT the diameter) has noticeably increased the dump/rollback cycle. A seat of...

    DB990 Clutch Access Question

    Thanks RG. This is a twelve. The tractor the fellow who suggested I look into not splitting has a twelve also, but, his has the high/lo shifter with the big dog-leg in it were the one keeping the grass from growing out front of the house has shifters looking identical to my 885. Something...

    DB990 Clutch Access Question

    Bump for another question if you check in RG. Clutch pedal has been strapped down for a week now, tried pumping the tractor with mine - no go. Talked to another 990 owner I know who it turns out, had to deal with a stuck clutch in his tractor. He said there is an access hole in the bottom of...

    DB990 Clutch Access Question

    RG, I was going by a description in a repair manual - CLUTCH Selectamatic Tractors publication #TP619 (in case you have the same). I just reread the section 'Operation - 880 and 990 Tractors'. You be right! No matter, as much as I'd like to be a good neighbor, I do not intend to split this...

    DB990 Clutch Access Question

    My 885 has a couple of covers on the clutch housing that once removed allows some access, I don't see anything like that on this 990. I can try blocking the pedal in the down position, sure can't hurt. A carriage bolt has been substituted for the clutch free-play adjustment bolt (threaded its...

    DB990 Clutch Access Question

    Have an 81 year old friend with a 990 that he really needs to make someone else's instead of trying to mow with it. Regardless, the clutch is stuck. My manual shows a pull type pressure plate which I have never dealt with before so I don't know what I don't know. Is there a way to get at the...

    "Generic" Parts

    Ran across a name unfamiliar to me while looking for a the water pump bypass O-ring that cost less than $20. You Oliver guys may know him, Rick Stair in Ohio (Rick's AgParts)? He has a non-India made water pump that is headed my way today. Fingers crossed. No deer for me. Eyes intact.

    "Generic" Parts

    Emailed AG Friday then called called them this morning. Nothing so far other than a recording stating how many weeks out they are. Hope I hear from them today. Found another online source - it's too cheap; Tractorwaterpro, $44 and change or less than half price to 30% of what I've encountered...
