Allis-Chalmers introduced the One-Ninety in 1964 and the Xt's in early 1965. The produced the One-Ninety Xt's thur 1971. During that time they built a little over 22400 Xt's. There were some changes made during that time. The first came in March of 1966 at serial number 9004, at that time all xt's had larger diameter axles, wider final drive gers, and a larger ring-gear and pinion. In December 1967 , AC introduced (what allis called the series two ) They removed the two horizontal bars in the grill and changed the rear fenders to match the 170 and 180 tractors . This occurred at serial number 19001. In December of 1968, at serial number 23001, AC introduced the series 111 and at that time they put the series three decal on side of the hood. There wqs a change made in the rear end. They changed the ring gear carrier to accomodate a four pinion differential. ( 4 spider gears in place of 2 spiders gears,) This reduced the stress on the differential when making sharp turns with duals, fluid and inter and outer wheel weights and pulling a heavy load. It wasn't a very common failure. |

XT story con't There were many reasons why the One-Ninety XT was and still is one of Allis Chalmers popular tractors. The large operators platform nearly 10 sq.ft. .perhapes the largest at that time. and what AC called (comfort control) where all the controls, the throttle, the power director lever, and all of the hydraulics were located at the right hand of the operator. ( probably another first) Also, the 12 position seat , whether you were large or small, tall or short, the seat could be adjusted for your confort zone. Same for the adjustable steering wheel. The 48 gal .fuel provided fuel for the entire day ( 8 -9 hours) and being located behind the operator for easy filling. It eliminated the need to have to refuel in the middle of the day. Another feature was the (what AC called the 2900 engine) a six cylinder 301 cubic inch direct injected and turbo-charged diesel . Nebraska test rated it at 94 PTO HP. however, there were many XT's producings 100, 105 hp right from thr factory |

The dual pto was offered in the later 1970's I don' t think there was a serial number break to pin point the time that it was available. It was an option. Rich

The story behind the story is this. Marketing had finally figured out that the future in the big tractor business wasn't a tractor where the operator sat down in the dust with his legs wrapped around a hot transmission. They asked engineering to design such a tractor with 75 hp. Engineering (foolishly) did just that with no room for hp growth. JD brought out the 4010 at 88 hp (only at Nebraska did that ever happen) a few months after the 190 was introduced. Of course, marketing was on engineering's door step the next day wanting 90 hp, and they wanted it right away. The engine people said, "No problem, we'll just add a turbo." The drivetrain people said the drivetrain would fail at 90 hp. The marketing people said they didn't care, we need the 90 hp right now (their commission checks depended on it). The rest is history. ------------- Mark B10 Allis, 917 Allis, 7116 Simplicity, 7790 Simplicity Diesel, GTH-L Simplicity Ignorance is curable-----stupidity is not. |

| actulally I know the man who made the decision, good friend. He spent many sleepless nights agonizing over the decision. Do we possibly get so far behind we cannot catch up to Deere and IH?, what will our dealers do without a unit to compete and sell? what will be the penalty to pay if we do experience massive failures? MANY of the XT's never had any issues, many failed quickly. AC lost many sales because the 4020 simply had better brakes, better steering, better dealers and a syncro tranny. The 4020 was not without issues itself as to reliabilty especially in the electrical and conveniece / servicibilty and clutch areas. The XT could not be beat in peppy engine performance and pulling power however, read turbo. |

 Very good to see the discussion of the 190, i had and sold one and now have another and have questions about it and will appreciate any help! I bought this past summer a 190 to use for mowing baling etc, and am doing some of the touch up things I want to do. It was sold to me as a 190, however on the torque tube is says 24505 xtd. my serial number books say both 190's and 190 xt's were built during the 1969 time frame so what is it? xt or not? It has a 2800 diesel engine and dynos at 77 hp. But my I&T manual says there is a transmission Serial # and Type number. Can a person tell the differences and does somebody have a transmission serial # reference and would it tell use what type of transmission? The Serial # is C169169 Type 7.842. So what is this tractor and is it from factory that way or is peiced together. I do know Allis and other OEM's will some times put parts together ( that don't match supposed to be ) to finish a run . I do like driving this one,i think it is better than my 185 and just fun to be on. Tractorman------------- Play on 38 B 49 WF , working on D14, D15 B10, Bee 12 B110. use 185 and 190 |

| I don't care what the serial number is (XT or not) it isn't an "XT" unless it has the turbocharger to make 94 HP. |

I understand the whole 190 non turbo,190XT turbo. What is the difference between a 190 gas, and a 190 XT gas? Was it the 265 on the 190 and 301 on the XT ? If XT meant it had a turbo, why was there a 190 XT series III gas ? As far as the pto goes, you could get 540, 1000 or dual. With dual it could be hydraulic ingagement,on the console or the big lever on the left. I think that was a killer on the 190 also,no true live pto. It is still my favorite tractor though

| The really sad part about the rush of the 94 HP "XT" was the 4010 (84 HP) came out in August of 1960....the 4020 Power Shift Deere (91 HP) was Nebraska tested September of 1963.....the mighty 190 (77 HP) came out in the October of 1964. (Neb tested in April 1965) and was already way behind and had been since late 1960. I always wondered if they had the heavier driveline in durability testing when they introduced the "XT" series to the public?? I will say this, when the high platform and "console control" was introduced, it really set a standard for others to want to follow.....including Deere!! |

Another question on torque tube stamping; what was the propane tractor stamped with?
Did they stamp "190P"?
Have seen factory propane units with "XT" on the end of the stamp and wondering just how they stamped them from the plant?

from what i heard the the 190xt was originally going to be called the 190xp because of the "extra power" but i guess it was decided to change it to xt just because it sounded cooler and catchy. i have a gas 190xt with the snap coupler hitch. its a early model with the full fenders and it pulled around 85-86 on the dyno before the clutch started to slip. but otherwise its good running.

The real 'killer' to the story is the engine Harvey sent up. They did not develope a true 94 hp torque curved engine , but rather pulled one off the shelf that had the rollers in the pump opened over the hp range and limited by the torque screw. This meant that when the engine was dropped below rated load the roller to roller setting took over and the torque exceeded a normal curve. Add that to the fact that about ever tractors seal was broken (including my dad's from some mystery novice somewhere in the house) and wa-la 115 hp . The first 190's were almost D19's - proir 2774 - in fact - this is scary - the pinion shaft - spider gears etc out of a late WD45 is the same as the early 190's 2 pinion set up - rivets and all. The factory assembly of shifting forks fit to gear shift in was non existant. In fact many tear downs from gear jump indicated shift collars that were not even 1/2 shifted into for example 3d gear - thus the mushrooming of coupler and spur teeth and early failure and gear jump outs. (as well as bearing loosening due to either poor set up or excessive loads and letting the gears move away from shift collars. ) Thus some units that by luck were set up correctly never failed -some had normal service lives, others barely made it off the delivery truck.

| Thats true on the gear jump out , guy i know was driving a new 190 around the dealers lot and it jumped out - thats not good advertising |
Posted By: skipwelte
Date Posted: 11 Feb 2012 at 12:38pm
| I remember the last few 185s I sold also had gear jump problems, due to the same reason-improper set up at the factory. The counter shaft bearings were loose, the shift rails didnt alow the couplers to engage the gear splines far enough. The service manager from the Des Moines branch came up and we tore two tractor transmissions down and properly set up the shafts, gears and shift rails. You can apply the same techniques to WD45, D17s, D19s, 170s. 180s and to a certain extent 200s. A lot of good background information, just the way I remember it. Thanks guys!! |

I'll try to answer some questions, hopefully shed some light on the 190 story as i saw it.
to Tim; I don't believe there was a designation for LP, it would have read "190G" and been a 301 engine. I don't remember a 190 LPG and none is listed in the 1964 literature,
the one with the handsome guy in the seat. To DRallis; No, there was not at 190 introduction a 4 pinion on test as far as I know. The 2 pinion was shot peened and was a better one that previously was used.
Tractorman;with the 2800 engine it should be marked 190XTG, as there was no 190LPG
(I got my fingers crossed)on that one. 4 Pinion or big axle has a bulge on axle housing,
outer end and can be in 190's also as complete exchange rear ends were used. Chuckz

Part II:To Ilgleaner;The 190G hafd a 265CI and the 190XTG had a 301CI.The 190 did not have an independent PTO and it was not refered to as such but rather as a Live PTO
and that is the correct industry designation, and yes it hurt sales some.
To my knowledge A-C did not piece tractors together to use up parts.
To tbran; When the load was increased the torque went up and the engine did not die at
1800-1850 like a deere 404 engine, the govenors on the pump would let it lug down to the 1650 range and the HP increased, transmission would not handle the load. HP is a calculated figure and Nebr tests are run at rated engine load and calculated. Now I'm confused, oh well. Chuckz

All the way back to Richmar's original post... I was always told Allis switched to the 4 pinion diff. at the same time as the larger axle, so if you found a 190 with the large axles you have a 4 pinion diff. is this true? our 190xt is a ser. 1 from the bell housing forward and a later ser. from the bell housing back with large axles and 4 pinion diff. we bought it in 1975 used, with new paint:) Must have been a driveline failure tractor. It was an awesome tractor for us ever since. I wonder if these serial number questions are due to rear end swaps like ours. Here is ours today. I am thinking about painting it again. I restored it in high school, in the 90s, wrong color and has the wrong decals, all I could find at the time. The aftermarket has come a log way:) |

Four-pinion differential came into production at sn 23001 which was the Series 3. Many older units got a four-pinion kit (which included a new ring & pinion gearset) installed when the two pinion differential failed, as was fairly common on a moldboard plow tractor. |

We had a series I that Dad bought new in 1965. AC made two upgrades to the rear end 100% at their own cost. The third time was at Dads cost. I don't know what was changed each time. I know he traded it for a new 1971 series III after that, so it was 4 or 5 years old when the rear end went out the third time. We were having trouble with the hydraulic pump when it was traded off. The series III never pulled as hard as the first XT did but in 5 years we never had any trouble with it. ------------- AGCO My Allis Gleaner Company |

I just bought a straight one ninety with the 265 gas engine and the small axles. It hadn't run for a few years and had a push rod out of position. It runs good now except
that I can hear valves hanging up and poping at an idle. Is there an oil additive that can cure this or do I need new valve springs? ------------- Nothing is impossible if it is properly financed |

Rislone might work. Another way is to change the oil to a high detergent oil. Most diesel oils have more detergent in them, and synthetic oils have even more. If it were my engine, I would put Mobil 1 5w-40 turbo diesel oil in it. That oil is also rated for spark engine use. And then put a load on it for a while. ------------- Mark B10 Allis, 917 Allis, 7116 Simplicity, 7790 Simplicity Diesel, GTH-L Simplicity Ignorance is curable-----stupidity is not. |

| The one I bought is a 65gas XT with a 301 that is dated 64. It has the 2 and 3/4 axles. Something that is neat is the lever behind the tractor under the tank that you put a jack handle in to raise and lower the 3PT. I heard the newer ones didn't have it. Someone thought it was probably unsafe. There is a bungee cord tied to the sea After I got the slop out of shifter linkage it feels tight and I can't get it to pop out of 1 through 3 but 4 you can push the shifter quite a bit further from were the detent is. Isn't there a fix for this like redrilling detent hole? |
