My father in law inherited an Allis Chalmers grader from his father but has no clue what exactly it is. That hasn't been a problem till now, because it needs a generator and a carb rebuild. It appears that the ID plate is gone so are there any other casting numbers or VIN locations to help determine the year and model? Thanks.

Since it has a mag instead of a distributor it is probably an older machine with the 201 cu. in. engine and a 6 volt electrical system. Should be a metal tag on the frame next to where you step onto the machine on the right side. The serial number will tell the year of the machine. There are people on this site that have information on serial numbers and year of fabrication. There are suppliers on this site that can supply carb kits. I use to own a D grader that was slightly newer and had a distributor and coil and I switched it over to 12 V and replaced the 6 V generator with a 12 V alternator. Because I had a coil I had to switch the coil to 12 V. ------------- Jack of all trades, master of none |

| The little tag on the carburetor should have the carb number on it to use to get a kit. |

Thank you all very much for the help. I was expecting an email notification if anyone replied to this thread and one never came so I assumed I'd hit a brick wall. I logged in to do more searching and found several responses. Thank you.
Apparently the "metal tag" that has all the important information regarding the machine is missing. No clue why someone would remove that, but its gone. Is there another location where the serial number would/could be located? If we can just find that number I think it will give us any and all information we would need.

The D grader first started in 1949. I would say yours is mid 50's. The one that I had was a 1959 and had the D17 farm tractor engine which was 226 cu.in. and had a coil and distributor. Yours would have the WD farm tractor engine with 201 cu.in. and a magnito otherwise the remainder of your grader and mine were almost identical except that mine had a cab and was painted orange. One thing that I would check is the rubber boot on the shift lever. If it is damaged or missing it will let rain water into the transmission. I replaced mine with the rubber boot from the CV joint from a front wheel drive car. These are simple machines but require a moderate mechanical ability to work on them. ------------- Jack of all trades, master of none |

I am looking at a AC D grader, SN D-5332 on one tag and SN 13058 on another tag. Could someone tell me the year and what engine it has. It is a gas engine. Also what option's to convert it to a diesel engine. Thanks |

The GAS model was called a "D" grader... the Diesel option was called a DD grader ... dont know what it would take to "convert" to diesel... Assume you would use an ALLIS engine to match up to the bell housing ? If other, you would need to modify / adaptor plate / clutch.. ------------- Like them all, but love the "B"s. |

Do you have info on what engine it should have? Thanks |

It would have the Allis 226 engine. Very common as it was used in the farm tractors, combines and as a power unit for pumps, generators an sawmills. It has been a couple of decades since I sold mine so I don't know who is a good source for parts. There should be reproduction manuals around. They were small but a very capable machine. It look as if it has been well maintained. ------------- Jack of all trades, master of none |

D grader engine would be the same as a WD45 farm tractor... 230 diesel or 226 gas options.

I gave all my data and information that I had on D Graders to the new owner a few years when I sold it. If my memory is correct I think that the diesel was a 6 cylinder and slightly longer so the hood and radiator mounting were different. ------------- Jack of all trades, master of none |

Here's a long skinny read on the D-grader, AFAIK, its still being made today. Sorry about the appearance, something must be screwy with their site, today... https://www.constructionequipment.com/topical/historical-equipment/article/10708588/allis-chalmers-compact-grader" rel="nofollow - https://www.constructionequipment.com/topical/historical-equipment/article/10708588/allis-chalmers-compact-grader ------------- Source: Babylon Bee.
