Abstract
A counterweight mounting assembly has a counterweight mounted thereon and a shear pin is extended to dispose it in aligned bores formed in the counterweight and in the frame of the vehicle. When the counterweight is lowered for removal from the vehicle, the operator first pulls on a handle secured to the shear pin to retract the shear pin into a stored position within the counterweight. First and second stops are provided between the counterweight and the shear pin to hold the shear pin at each of its extended and retracted positions.
