| Picked up a CA today and noticed a few things. There are no generator bracket holes in the block. It was mounted to flat stock with weld nut and the flat stock had a right angle on the front that picked up a bolt on the front of the block. Also the governor housing has no lube fitting and tube going to it. I don't know B's or C's so could this be one of those? Bracket doesn't look cobbed and lack of lube point doesn't look altered. |

it could be an early B motor. Look at the serial number on the left side of the bell housing flange and see if it is a BE instead of a CE motor. no generator mount or gov lube tube on the 1938-39 years ------------- Like them all, but love the "B"s. |

It's either an early BE block or possibly an RC block. The RC is already 125 cid like a CA, and if it's a BE block it also has likely been updated to later 125 cid specs. Kip ------------- HANSEN'S OLD ORANGE IRON. Showing, Pulling, & Going!! |

| If there is no number on the flange where you usually see the CE number, look on the boss on the rear of the block, just above the curve. Early B engine numbers stamped there. |

OOOPS, green is not good inside an orange tractor ! could be a bog problem, or could be a freeze plug under the rocker arm. take off the valve cover and look. ------------- Like them all, but love the "B"s. |

When I got my CA and you looked down from the top you saw green too... But it was grass.

| I wouldn't mind having a CA but I've got to see some "green" before I can ever get one. LOL |

| I bought my first Allis B about four years ago, and haven't had any 'green' since... |
