here is a close up of the steering assembly. Simple, yet works flawlessly
this is the wheel loader that is on my peterbilt lowboy. the bucket works with two linear actuators, and one M motor. There is a gearbox in front of the engine that switches between raise/lower and dumping the bucket. The exhaust pipe behind the cab doubles as the selector switch between functions. there is also a functional drive train, so it could be set up for RC.The steering works via a transverse steering arm connected to a 36 tooth gear. There are two steering links attached to this arm which are then attached to the front half of the loader. This steering system is incredibly smooth and precise. It can also be steered with the steering wheel in the cab, since the 36 tooth gear is right beneath the driver's seat.
