Let The Build Begin!

[Lil Giants]

I don't seem to have the correct detail shot on file of how Stahl locks their wheels to the output shaft of the gearhead motors, hopefully this one will be sufficeint?

There's an approximate 2.5 or 3mm hole drilled through the gh motor shaft, inward about 5mm of the end for a 10mm length steel pin to pass through. You can see the slot in the wheel of the pic. The entire wheel slides past the hole on the gh output shaft so you can install the steel pin.

Pull the wheel outward to set the pin into the wheel & it's all held in place by bolting on the simulated planetary hub cover.

This is the best method I've ever seen of locking a wheel to a driveshaft, no chance of any set screw(s) coming loose.

The TLT axles in my 6wd semies work on much the same as this principal, but have a big ugly nut showing.
