Hey there.
I have had a few posts on recently, trying to find help with some problems with a WD45 that I just purchased.
Like: why doesn't my tractor have a thermostat? why does my WD45 have a WD engine, but it's not a regular 201? I have now figured out that I have a LeRoi D201 engine, and it has a water manifold with no thermostat housing in it. I also have a TSX464 carb (that runs like crap). I just stuck on a smaller Zenith from a WD that has been sitting for 12 years, and my tractor now runs smoothe. My questions are: - Do you recommend sticking with the LeRoi engine?
I plan to antique tractor pull with it, and some folks say they have more power than the regular WD engines. (more than the regular WD45??). - Would a D201 be comparable to a WD45 226?
- Should I install a water manifold that has a thermostat housing in it? Did engine came without one for a reason, but am not sure if it is because of its original life, maybe in an air compressor, that had a different setup on it. Now that it is in a WD45, maybe it should have a thermostat in it.
- Carburetor. Should I replace/rebuild my (supposedly new) Marvel Schebler TSX464 because it has the larger air intake throat, or is the smaller Zenith a better carburetor?
any and all help is appreciated.

| It should have a 180 degree thermostat, with a 4lb pressure cap. Without a thermostat it may never reach a high enuf temp to evaporate off the condensation in the engine oil.And they just plain run better at 180- 190 degrees. |

My best guess is, when it lived in an air compressor, the load was constant for the most part, and didn't build a lot of heat, we had one for a while, and it didn't seem to work too hard. The WD45 engine would be better for pulling, just because of the slightly larger displacement, and higher HP. I wouldn't pull a tractor that didn't have at least a stock set-up, there are so many out there that "modify" their "stock" setup, you wouldn't have a chance.

Hi Orange Blood.
So I guess what you mean, by saying "I wouldn't pull without at least a stock set up", you mean put the thermostat in there? Do you really think that the No-Thermostat set up isn't stock? I "think" it originally had a thermostat, but like I said, having this different engine, I'm not real sure. thanks! |

No I wasn't reffereing to the thermostat, I was referring to the whole engine. Let's just pretend for a moment that everybody at the pull played by the rules, which many do, but many do not. In the stock class, your WD45, with a smaller non orriginal motor, putting out 35ish belt HP, would loose everytime to a true factory WD-45 with the larger displacement engine putting out 45ish belt HP, all other factors being equal. My question was why would you even enter the pull, if you don't at least have the stock amount of displacement and HP that you are allowed. Now let's add back that many "stock" tractors have been heavily modified inside the block and head, now even if you tractor had what the factory put it out with, you will have a hard time beating the other tractors. ------------- Still in use: HD7 WC C CA WD 2-WD45 WD45LP WD45D D14 3-D17 D17LP 2-D19D D19LP 190XTD 190XTLP 720 D21 220 7020 7030 7040 7045 3-7060 Projects: 3-U UC 2-G 2-B 2-C CA 7-WC RC WDLP WF D14 D21 210 7045 N7 |

Where do you get the HP rating for a Leroi D201? From what I can find the D201 is rated at 43HP same as the WD45. Just because it has no thermostat doesn't mean it's a 201 engine. It very well could be a larger displacement engine with older parts bolted on. Some pullers will pay good money for a Leroi engine because of the differences and the things that can be done to them to pull better than an Allis engine. ------------- http://www.ae-ta.com" rel="nofollow - http://www.ae-ta.com Lena 1935 WC12xxx, Willie 1951 CA6xx Dad bought new, 1954WD45 PS, 1960 D17 NF |

Orange Blood, I know a guy that dynos his MM UB at stock rpm and gets 150hp out of it. He often looses to other tractors that won't dyno 150hp.

Tucker, I wasn't trying to lay down fact, it was a discussion. I never said it was a 201, deere did, I am working with what I am given, and I am not claiming to be a know it all, that's what makes this place great it's a discussion board, if I'm wrong, I am sorry, but like you I am assuming some of the unkowns. I must have really screwed up when I posted about the thermostant, seems everyone is getting hung up on it, to be clear, I don't give a rats tit about the thermostat, and it doesn't have any bearing on what I am talking about!!! ------------- Still in use: HD7 WC C CA WD 2-WD45 WD45LP WD45D D14 3-D17 D17LP 2-D19D D19LP 190XTD 190XTLP 720 D21 220 7020 7030 7040 7045 3-7060 Projects: 3-U UC 2-G 2-B 2-C CA 7-WC RC WDLP WF D14 D21 210 7045 N7 |

I'm going to DYNO mine later this week.
I couldn't get it to run right, but even though I put a smaller carb on it, it runs smooth now, smooth enough to DYNO it to see what it's got.
I just talked to Unstylish, and he thinks it will only put out 32-34hp. I don't see it putting out 40some, but I'll be pleasantly surprised if it does. I'll let everyone know what it dyno's. I'm going to put a different manifold and a thermostat on it first. Thanks again Unstylish! |

Chill a bit. I should have quoted deereequipent1 when I commented on the thermostat and the cubic inch issue. He could have a mix and match set up because of the no thermostat and a short head??? I don't know. Sorry if it sounded like that was aimed at you but I was just trying to point out the possibilities.

CTuckerNWIL:
with this post, are you saying that some D201 and some D226 parts are interchangeable?
I know you can put some WD45 parts on a WD engine, but it don't make it a WD45 engine, and the same would be with the LeRoi's, but I am hearing that some parts of the LeRoi engines have some Preferrable characteristics, compared to the Allis parts. |

So basically, I won't know what I have, until I DYNO it.

Don't neglect the speed you test it at. An engine rated at 1500 rpm will produce considerably more horsepower at 2500 rpm, though it may lack balance for smooth running at that speed. Gerald J. |

Take the spark plugs out and use a piece of wire to measure the stroke. Then do a compression check. That might help tell what you have. If there are any Leroi experts out there, I wouldn't know where to find them. There is a post on Smokstack about Leroi engines and 6 different guys say six different things about the engines, from "they were made by Allis Chalmers" to "all engines had the flat head with combustion chamber in the cylinder." ------------- http://www.ae-ta.com" rel="nofollow - http://www.ae-ta.com Lena 1935 WC12xxx, Willie 1951 CA6xx Dad bought new, 1954WD45 PS, 1960 D17 NF |

I'd ask ML Pankey. Seems like he was interested in anything LeRoi that could be used in an A-C. ------------- "Any man who thinks he can be happy and prosperous by letting the government take care of him better take a closer look at the American Indian." Henry Ford |

I had a fellow call and ask if I had any rods for a WD . To make a long story short his engine turned out to be a Leroi. The rods are different, larger and look strongerbut either the crank end or the wrist pin hole were wrong ,can't remember. there are internal differances in these engines. This is all I know about the Leroi's. Scott ------------- Allis Chalmers still exist in my mind and barns |

I assumed these Leroi engines were built by AC to Leroi's specs for power units. Just guessing here. Scott ------------- Allis Chalmers still exist in my mind and barns |

| The engine probly had an inline thermostat in the upper hose. I have a d201 in my garage right now that is that way. I also have the original manual for the leroi d201 and in it is the torque and hp charts for the engine, and they are identical to an allis wd 201 cu in engine. There is zero power difference. |

its a secret on the 226 leroi any way be verry verry quiet and do not look for a picture of the 8 inch long canted leroi rod or combustion chamber head or propane intake.. ------------- people if they don't already know it you can't tell them. quote yogi berra |

Deeree,
If it were me, I'd do a real good job of cleaning up that TSX-454 carb and when you take your tractor to the dyno, do a test with both the larger and smaller carb.
I think the comparative results would be very interesting. I know I'd like to see that!

I dyno'd it today, in the rain. So with the smaller carb, being very damp outside, and not being able to build up heat. It didn't do well. I don't even want to post it! Isn't a WD suppose to be like 32-35hp, and a WD45 42-45 hp? This is well below either! |

According to the AC bible under NE test results the WD 201 gas had 34.63 Belt HP, PTO HP would be ever so slightly less.
The WD45 226 gas had 43.21hp at the belt. ------------- Still in use: HD7 WC C CA WD 2-WD45 WD45LP WD45D D14 3-D17 D17LP 2-D19D D19LP 190XTD 190XTLP 720 D21 220 7020 7030 7040 7045 3-7060 Projects: 3-U UC 2-G 2-B 2-C CA 7-WC RC WDLP WF D14 D21 210 7045 N7 |
