| Can someone point me to the manual pages or give me some knowledge on how to make sure the power director is adjusted right? Neutral position acts a lot like low range. |

Might have a warped clutch, or a bad valve... Or linkage not centered? Lot of them have clutch drag, until they get warmed up, some have it even after getting hot, very few will have no drag when cold. Our first XT bought back in 1975 had all new parts in rearend (harden axles too), transmission, and two speed. It got used on the plow, disc and extensively on the round baler... and now going on 50 years, the tranny starting to jump out of 4th and the high range slips under heavy load. The hand clutch was awesome while the other 190 and XT would not sit still, had to use the brakes to stop them. Tried to adjust the linkage on the one and the other has problems in the clutch pack. Sure hope when the clutches get replaced in the slipping XT, that it doesn't start creeping or drag in neutral like the others do. A dragging 2 spd. clutch can be a real pain to deal with... if you put them on the round baler and need to step the foot clutch in every time you go to shift the transmission.  ------------- He who says there is no evil has already deceived himself The truth is the truth, sugar coated or not.

| Warped or broken discs and plates can cause this. Bent ears on the clutch pistons can also contribute to it. Nothing you can really do from the outside. Your perception may also be a true neutral and with hydraulic oil temps less than 140 to 160 degrees, there usually isn't a good neutral. You got 9 driving discs flooded in oil causing drag and yes, it does still feel like low range. If it pulls a load in both ranges and doesn't slip, I'd do nothing. Cold oil temps are the most likely culprit. |

It's strong enough the brakes barely hold it back. Haven't hooked it up to a real load to test. I'm used to my D15, where even cold "neutral" can be achieved with light brake pressure. I was hoping there was some gate or valve release pressure or something I could dial back just slightly to get it to lighten up in neutral. Thanks! If I have issues pulling I'll be back. I saw another thread about power director repairs I'll look through too. |

| They will ALWAYS creep the least when in road gear. They will ALWAYS creep the most in low gear. It's a mechanical advantage thing........ |

Im going from memory from a long time ago but i think if it was mine id get some pressure guages and make sure the linkage is adjusted so theres no pressure on either clutch when the handle in in the center position. If i rember right theres ports in the valve for that purpose. Then youd know if its in the clutch itself or if it acually partially engaged ------------- 1984 80780 1957 D14 DES 300 with 25000 engine 616 tractor |

I was thinking there should be something like this, but I couldn't find the manual pages for it. I'll poke around. Like Doc says there's always some slippage, but I'm not confident leaving it in gear and using the brakes and getting out. Which I am confident in my D15 doing that, and my Diesel 190XT. Just this Gasser.

| Leaving the transmission "in" any gear and dismounting the tractor has never been advised, regardless what model. The truth of the Power Director clutch linkage is this: some will think the "neutral" (center of the stroke) zone can be changed or needs to be improved. That linkage only has limited adjustment. Even when adjusted spot-on, there is barely enough travel to reach full stroke in LOW and HIGH ranges and neutral is right in the dead middle. Little change is available because the total stroke is barely enough as it is. |

I'd be tempted to run it for a while, change fluids, and see how it feels after some time before breaking it down to look for warped discs or other internal problems. As others mentioned, those hydraulic PD's can drag a fair bit in neutral - especially when cold. When I bought my 180, I assumed something was was broken/bent because it dragged so hard in neutral. I didn't really care as it was dirt cheap and I was expecting to only use it as a stationary power unit for the sawmill. But after a couple of hours use it seemed to really free up some. I later changed the fluids and that made an even more significant difference - there's now only minimal drag when cold and no drag when warm. The old fluid didn't seem that bad, but I suspect it was just a little more viscous and caused that much more drag. A you no doubt know, the hydraulic PD's of the 180 & larger units are different animals than the mechanical PD's of the 170 and smaller/earlier units. But regardless of which type/tractor you're on, I'm 100% with the Doc on his last post: You really don't want to rely on the PD neutral of either type if you're going to hop off. You really want to be putting the tranny in neutral.

First thing I did was change fluids. It looked like a milkshake. Manual said 32 qts, that's not what came out. If it pulls in high and low I'm not going to tear it apart just cause neutral isn't perfect. I'll be running a square baler, plow, disc, and sprayer, so the hand clutch isn't essential. It's "live" hydraulics, too, so foot clutch with loader work will be fine.

| After draining both drain plugs (2) it takes 5 gallons to refill, which is 20 quarts. |

About 5 gals came out, so guess I'm better there than I thought. But now I'm more confused. Are both drain plugs just for the hydraulics, or do they drain the transmission too? |

| Don't know 190's but my 220 uses same oil for hyd,trans & rearend. |

Manual says 32qts for one 36qts the other, two kinds of fluid. I went the recommended route and used the harvest King vintage tractor Hy-trans in both. There's two fill spots, and I only saw two drain plugs. Did I actually drain both? |

| Transmission drain plug is behind the battery box. Differential drain plug to the left of the PTO on the rear of the tractor. Both take 1 1/8" wrench. Gallons depend on which dipstick is used but 8 to 10 gal is the range. One compartment. One fill hole. Two drain plugs. An owners manual would clear this up and provide pictures. |

Owners manual didn't say at all where any of the actual drain plugs were and are the actual source of the confusion, also no pictures. At least the one from jensales. It says two different types of fluid and two different quantities which implies two different compartments to go with the two different dipsticks and two different drain plugs and two different service intervals. It only shows where the final drive drain plugs is, which takes a different fluid and has a different service interval and different level checking method, is it the same compartment as the transmission and hydraulic too? |

An Allis-Chalmers owners manual does indeed show all these check points and drain plugs. There are two final drives...left and right. Drain plugs are obvious. Fill plugs are on the side of the rear end housing under the lift arm cylinder rod. Takes 2 gallons of 80/90 weight in each side. |

The Jensales 190 190XT operators manual 100% does not show drain plug locations for the transmission or hydraulics, it mentions there being one for each but there is no picture. It shows where the final drive drain plugs are, that's it. It shows and states two separate check/fill locations for transmission and hydraulic in the cab, does these fill the same compartment despite the manual saying they should be filled with different fluids?
