A tire mounting method for automatically mounting tires onto hub bolts of a motor vehicle using a tire mounting device having a first working mechanism and a second working mechanism. The method includes feeding the motor vehicle intermittently so that hub bolts of a front wheel and hub bolts of a rear wheel are successively positioned in a tire mounting station. Tires are gripped by a tire gripping unit of the first working mechanism, and nuts are successively temporarily tightened onto hub bolts of front and rear wheels to which the tires are mounted. The nuts, which have been temporarily tightened, are then fully tightened using the second working mechanism.

The invention relates to a centring arrangement for a component carrier, in particular for a mounting frame for structural aircraft components, having a centring pin, a centring receptacle for the centring pin, and a rotary drive for rotating the centring pin about a longitudinal axis of the centring pin, so that the centring pin can be brought into centring engagement with the centring receptacle as a result of the rotation. The invention further relates to a method for centring and locking a centring receptacle.

A guide rod, which has a diameter expandable tip end portion and restricts the oscillation of a connecting rod and a piston, is inserted into a cylinder bore via an opening adjacent to a crank chamber of the cylinder bore, and the piston is inserted into the cylinder bore via a cylinder head mounting side opening with the connecting rod positioned at a leading end. The diameter of the tip end portion of the guide rod is increased in a hole of a semi-circular arc-shaped end portion positioned at tip end of the connecting rod in the insertion direction, and thus the connecting rod is engaged with the guide rod. The guide rod moves and the connecting rod is pulled into the cylinder bore until the semi-circular arc-shaped end portion of the connecting rod sits on a crankpin of a crankshaft.

The invention relates to an apparatus for the assembly and disassembly of hydraulic cylinders, composed of a pedestal-like machine frame having horizontally arranged guide means which bear, in displaceable manner, a receptacle for the cylinder barrel of the hydraulic cylinder, at least one receptacle for a support and a receptacle for a tool, and furthermore having a holder for fixing the piston rod of the hydraulic cylinder. According to the invention, the holder for fixing the piston rod has a centering carriage which is driven by a centering spindle and which comprises a piston rod receptacle, wherein the holder is designed to be rotatable about the longitudinal axis of the machine frame and the rotational movement is realized by means of a torque-controlled electromotive drive.

A surgical stapling instrument. Various embodiments include an actuation system for selectively generating a plurality of control motions. A surgical end effector is operably coupled to the actuation system. The actuation system interfaces with an actuation member configured to operably engage rotatable camming members to fire staples within the end effector into forming contact with an anvil portion of the end effector.
