Thought I'd start a new post for this one. If my CE engine has the serial # on the rear center of the block, how about you guys with early RC's, like Larry Karg's #9. ------------- Waukesha B, B, IB, G, styled WF, D15, 615 backhoe, 2-Oliver OC3's, 4 Ford Model T's, 3 Model A Fords, AV8 Coupe, AV8 Roadster, 1933 Ford Wrecker |

I thought that only the BE engine had the serial # at the rear of the block.
The CE engine serial # is on the side of the engine behind the air cleaner, on the flange.

Bob, I think that was a common misconception until Lon posted pictures of his new C with engine #CE35. http://www.allischalmers.com/new/forum/uploads/196/000_0081.jpg - http://www.allischalmers.com/new/forum/uploads/196/000_0081.jpg ------------- 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 |

To further complicate the Bs with BE or CE engines, Cs with CE engines and the RC with their special 125 engines and their specific SN locations question , add in the R and CR power unit engine prefix locatrions since they will both bolt up in tractors.
Did a original RC 125 engine have its own special SN prefix?
Terry Deans AC data book in the RC specs gives the engine SN location as, "Rear" of the Block. C tractor specs locate the number as "Left or Rear side of block". The B with the BE block locates the number as "Left or Rear side of block". B with the CE Block spec locates the number as "Rear or Left side of block".
If the Data Book research is correct you can't have it both ways on a RC. Or the CA where it says "Left side of block on rear flange"

| For some strange reason I thought the RC engine had its own letter prefix. I think now that what I was looking at was a RC with a power unit engine with the CR prefix on the left side of the block on the rear flange. This was a good while back at the Pawnee GOTO where I recall asking the owner if the engine was original RC. I can't remember what his reply was. I do remember it was a well restored RC and painted Corporate Orange. |

I'm not sure about power units but I thought RC's all had CE engines? ------------- Waukesha B, B, IB, G, styled WF, D15, 615 backhoe, 2-Oliver OC3's, 4 Ford Model T's, 3 Model A Fords, AV8 Coupe, AV8 Roadster, 1933 Ford Wrecker |

| I had an RC that I sold a few years ago and it was an R engine, and it was on the back of the engine on the flange. HTH |

| I believe that the CE engine did not appear until The first C tractors were built, hence the CE engine which around 43 or 44 they started putting in the model B for more power. |

The RC should have an R prefix. My tractor S/N is RC 2211 and the engine is R 2238 G, and it is on the flange. |

Tom, as soon as I looked at your pic I thought "I could just look at my RC". Why didn't I think of that before? Mine is RC5084 with engine R7468G. So that answers my question on RC's but I wonder how many C's have the # in the back like mine? ------------- Waukesha B, B, IB, G, styled WF, D15, 615 backhoe, 2-Oliver OC3's, 4 Ford Model T's, 3 Model A Fords, AV8 Coupe, AV8 Roadster, 1933 Ford Wrecker |

| Rich, I wish I had something to report on the D17 Industrial. I took the engine apart and found the bottom webs cracked open, the middle one split right through to the main bearing. My parts tractor was a series one and had the old bypass oil set up - it also had a welded up block so I didn't want it in any case. I got another series three block and took the sleeves and pistons out today, so far it looks very good with no cracks on top or on the bottom, but that's as far as it has come. The rest of it is in chunks in the shed. |

This won't help the confusion any, but my C has a B engine in it. Engine Number BE #### K. On left side rear flange. According to Engine number, it was late 1940, maybe early 1941 kerosene 116 CI engine. So B engines had numbers on left flange in 40-41. Maybe some were stamped in rear and some stamped on left, just depending on who was doing it, and how long they did it before being told to do it differently. ------------- I didn't do it! It was a short, fat, tall, skinny guy that looked like me! |
