Hi Jennifer.  Yes, they are caterpillar tracks.  The 8880 tires were not the
correct shape to be telehandler tires, and wrapping the tracks around them was
the only way to make them taller and narrower.  I think real ones are 4-5ft in
diameter.  I almost got run over by a telehandler once- that's how I know how
tall the tires are.

The 45982 tire (the big ones on the Backhoe) seems to be the correct shape, and
about same size as the 8880 tires. Get them and you don't need the caterpillar
tracks.

BTW, that Bimba piston should allow us to make a fully pneumatic crane truck. I
should try to fit one on the 8460. :)

Glad to be of help Keith!

I did not use the tires from the backhoe because in my design, the differential
has to fit in between the A-Frames (not just between, but inside).  The only way
to put the back hoe tires on my 4WD suspension is to angle the A-frames out
towards the center to fit the differential in.  This would not allow enough of a
steering angle.  It is very hard to explain. Another reason I used the 8880
wheels is to have axles with a large diameter and steer still far.  Of course,
since the design is so narrow, they can't steer far anyway.  I think I will have
to show you a picture to better explain it.

Thanks for the suggestion anyway.

Nathan
