| We were trying to move our 38 B today by hand (crank start but not today for some reason) and when turning the steering we heard a snap and then the wheel just spins. I pulled it and it looks like there should be a woodruff key locking the wheel to the shaft. Not sure where it went but it's gone. Anyone know of a source for a new one or have a schematic of the steering wheel area? Any help would be appreciated. |

If you talking about the steering wheel spinning it has a half round key. this drawing might help.

| My B did the same thing a couple years ago. It was the little stud on the "lever shaft" that rides in the worm gear. If yours is a 1938, it'll only have one stud, not 2 like in the picture above. |

If the nut holding the Steering Wheel on is tight, I doubt if it is the key. Watch the nut and the end of the shaft and see if they turn with the wheel. Gary |

| Just proves what I have always said; A lot of the problem is the nut behind the steering wheel ! |

This might have broke off or pushed back away it the steering wheel is turning the shaft, I have never heard of the shaft separating from the worm but who knows without ex ray vision.

| I just remembered buying a B with a ross steering box cover broke letting the shaft move the pall away from the worm. Something else to look for! |

| That pall will actually snap right off sometimes as well or wear out if someone put grease in the box instead of oil. I went through 4 boxes to build 1 good one for my B. |

Engine doesn't turn, AND steering is stuck? Pull it into the shop, let it warm up for a day, then try it. If they turn... drain the water out... ------------- Ten Amendments, Ten Commandments, and one Golden Rule solve most every problem. Citrus hand-cleaner with Pumice does the rest. |
