| I am looking at putting an L2 engine in my one ninety XT. Read somewhere, though, that an L2 with the 2900 is at 145 horsepower. Is that right. ..? That's pretty hot for a 2900, not. ......? If it is that much, ,it'd make a hot one ninety XT. Darrel |

Norm's book makes mention of 190XTs being easily turned up to over 120 hp. That's the reason for rear ends getting shelled early on. I can see the 2900 being 145 hp in combine mode - the intercooler would help with that. You are right though, that would be a hot 190 for sure! I'd love to see it in action!

| The combine engine HP is flywheel, the tractor is PTO HP. Different rating. MACK |

| 2900 was 130 flywheel HP.....2950/649I with intercooler was 145 HP. If it is a 1977-78? L-2, the 2900 with "DC" injection pump was 120 HP and DM-4 pump was 130 HP all flywheel rating. About 12 HP loss from flywheel to PTO on a 190XT chassis. |

| If the combine engine has an intercooler, then they are similar to the 7020. Still not the same. |

| Thanks, guys. I am not sure of the year on the L2. Owner said that he knows the engine is the 2900. Was a strong running engine, but he kicked the unloading auger on when there was ice in the hopper. Decided to park it instead of fix it. An old allis mechanic friend of mine would do the swap for me, changing the plates and all. Just going to be a baling tractor, and loader tractor, so a little extra power shouldn't tear anything up.

| A neighbor did that swap a few years ago. One problem he had was the deeper oil pan on a later crank driven oil pump engine will hit the front axle . I think a 200 has the front axle made so it sits lower giving more clearance for the oil pan. |

Interesting post, I found out after I bought my 190XT that it has a transplant 7020 301 engine. According to the injectors when I had them rebuilt. Other signs were the round rubber cap for the oil filler, and the high serial number of the engine compared to my brothers which was built the same day 4 serial numbers later. Still using the factory pump, so a detuned 7020 engine. Well, Ed Guenther fixed that for me this fall when he rebuilt my pump. 120 hp plus some. Lol. Hope the trans survives, will farm with her plus an occasional pull. I am in the middle of a complete paint job/restoration. A working tractor not a show piece although I think she will look nice in her new color. Will post some pictures of the paint progress. ------------- 1968 B-208, 1976 720 (2 of them)Danco brush hog, single bottom plow,52" snow thrower, belly mower,rear tine tiller, rear blade, front blade, 57"sickle bar,1983 917 hydro, 1968 7hp sno-bee, 1968 190XTD |

| 7020 tractor engines were always intercooled and the 145 flywheel HP 301 combine engines were also always intercooled. The 130 flywheel HP combines engines were never intercooled. The 120 HP combine engine was never intercooled and had a DC type injection pump. So, depending on the year of L series combine, it could have had 120 or 130 or 145 or 158 (426 block) HP engines. |

| Darrel we put an L-2 2900 in my buddies 190xt series 3....It's sitting at 150 HP...We had it dynoed...Never pulls more than a 5-16 plow with it and he's never had a lick of trouble...I imagine if he strapped a 6 to it he may have problems down the road but he's never lugged it. |

| As long as you don't do more than the tractor was made for,you won't have driveline issues. |

| I'm sure your allis mechanic friend would know how to turn the pump down a bit for safety type purposes. Although, would torque values be that different between the 120hp version and the 145hp version? Trev. |

How do I tell if this will be an issue, before I get into it too deep.....? Thanks, Darrel

| Darrel,nobody else said anything about an oil pan clearance problem. Maybe it is not an issue? Pete |

Pete you are correct. The oldest L2 would be a 1977. The 200 came out in 72. I am with you on this Pete ------------- Education doesn't make you smart, it makes you educated. |

I have a buddy that did one also. He said that it woke that tractor up. He has it turned up to 150 hp dynoed. I think the only thing he said about the oil pan is that the plug is on the side and makes a little more mess I think

All L2s had at the minimum the 130 hp 2900/649T Pretty sure the only 120 hp models were straight Ms, but possibly early M2s could have had the option. The 649I did not arrive till 1980, and was optional, the 130 hp was still standard. I think it was roughly at the 2 to 3 series change that the 130 was dropped and the 145 became standard. IIRC late in the 3 series the 145 became optional on the M series machine. prior to that it was 130 only. All L and M series combine engines 301 and 426 were turboed, but only the 649I was intercooled. ------------- Gleaner: the properly engineered and built combine. If you need parts for your Gleaner, we are parting out A's through L2's, so we may be able to help. |

| There was a change in the front booster when they went with the crank driven oil pump, it was changed with 200 verses 190. 185's were changed when they started putting crank driven oil pumps in them. My daddy installed a M engine with later pump in a 185. basically used the short block, had to change timing cover and back plate for hyd pump drive, had to cut out bottom of back plate to clear oil pump. Then used 185 head and injection pump and oil filter. After he ran tractor for a while we noticed front bottom corners of the oil pan bent in where the tie rods had hit the pan. It happens when the axle is oscillated and you are turn all the way. It has been running for over ten years now with no problem with bent pan. |

Did this on my XT. Issues, 1 flywheel - it will have to be drilled. 2. rear cooler routing interferes with clutch linkage.
3 front axle will have to be raised by welding another pivot on top of existing one and the rear mount will have to lowered to upper holes and weld and extension above to match holes. 4 Front plate - if you change, you will have to change fuel pumps - I drilled my mount to accept hyd pump and kept L fuel pump a DB vs Dm. and welded brackets for front frame mount. 5 The water pump/ fan will be an issue. 6. radiator inlet /out let is different. 7 dual filters for oil will not fit. 8 Front pulley will not fit - it will hit front cast housing. 9 alternator mount 10 tachometer drive = all can be done - it ain't no picnic...

yeah but when someone walks by my XT that knows anything about AC, they take a few steps, roll the eyes, scratch the head and reverse the direction and start noticing this ain't right,,,,, :-) of course most the tractors we farm with are 'Frankintractors' made from several donors... we call them Skunkwerked - area xxx51... half the fun in farmin'.... the grandson and nephew's all get upset, ask why we don't' have any new tractors like the neighbors.... I just tell them its an AC thing,,, they may or may not under$tand someday..
