[DML] Re: Angle Drive

["content22207" <brobertson@xxxxxxxxxxxx>]

Not only "modern" cars -- even my stable of antiquated vehicles use
speedometer takeoffs in the transmission.

I was told once that turning the UN-1 around backwards is why our
takeoffs are in the front wheel. Didn't make sense to me then: simply
adding an intermediate gear would change direction of rotation. I've
since decided that the cable run was the determining factor.

If someone really wants to engineer an improvement, my money is on
attaching the speedo to the transmission. Would probably still require
an intermediate gearbox, for proper ratio as well as acute cable
bends, but at least it would not be on a pivoting spindle or next to
the road.

Here's a good question: why is the angle drive lubricating screw
upside down? You have to disconnect the cable and spin it around to
lubricate. My suspicion is that our angle drives are adapted from a
right hand design (right wheel installation), which would locate the
lubricating screw rightside up. Also explains why the spindle cable is
wound the wrong way (on the right wheel predominant rotation would
tighten the spirals, not loosen them).
