  • bell houseing factory weld mil. 640

    640 civilian had a solid cross shaft cast - no cut. I guess they had problems with the angle and pressure - the cast would break. So they cut and re-welded them in the factory. Yup! That's factory correct for military 640. Take a look. Not sure if the angle on this one is correct. It may have been bashed around over time. But I think it's right.

    I think they were trying to get the rotational cross shaft arm to line-up with the universal joint that it's attached to with a closer right angle relationship when attached to the rod, to take the stress off of the casting. It's really kinda awkward the way the thing physically moves. Rod length looks to be very important for proper engagement.

    Another reason why guys would put a jockey shifter on I guess. A more direct path? Is that right?
