Abstract: A cab frame mounting system is disclosed. The cab frame mounting system includes a cab mount to couple to a cab. The cab frame mounting system also includes a frame mount to couple to a frame. The method further includes a pin to couple the cab mount and the frame mount to define a pin axis. The cab mount includes a bracket. The bracket has an upright member with an opening formed therein to receive the pin and an angled portion coupled to the upright member. The frame mount includes a mounting head. The mounting head includes a base structure and a protruding head member. The protruding head member includes an opening formed therein to receive the pin. Further, each of the upright member and the protruding head member include angled surfaces. The angled portion and the mounting head each have an opening formed therein to receive a restriction element.

Abstract: A method of forming a hole in a hollow blank during a hydroforming process is provided. The method includes placing a blank in a cavity of a hydroforming die, the hydroforming die being configured to permit a punch to engage the blank. An interior of the blank is pressurized with a fluid. Further, a cutting end of a punch is applied through a wall portion of the blank and into the interior of the blank to form a hole. Furthermore, the cutting end of the punch is removed from the interior of the blank such that the cutting end of the punch is configured to allow material of the blank surrounding the formed hole to move away from the interior of the blank.

Abstract: A method for hydroforming a tubular blank comprising the steps of at least partially closing the die portions of a die about a tubular blank, introducing a hydraulic fluid into the tubular blank at a first pressure, substantially closing the die portions about the tubular blank, partially opening the die while at least initially maintaining the pressure of the hydraulic fluid, and substantially closing the die portions at least a second time.

Abstract: A cab frame mounting system is disclosed. The cab frame mounting system includes a cab mount to mount to a cab and a frame mount to mount to a frame. The cab frame mounting system includes a pin configured to couple the cab mount and the frame mount. The pin defines a pin axis. Further, the cab mount includes a bracket. The bracket has an upright member having an opening formed therein to receive the pin. The frame mount includes a mounting head. The mounting head includes a base structure. The cab mount also includes a protruding head having an opening formed therein to receive the pin. The bracket of the cab mount includes a flange portion extending from the upright member. The bracket is coupled to the base structure of the mounting head with removable mechanical fasteners.
