Brand new, complete throttle pivot assembly, as shown. This mounts to the firewall on turbodiesel om617 engines found within the w123 chassis and also on some later 240D For Mercedes. Installation tip #1: Observe the position and orientation of the original pivot prior to removal. There is a curved section and a flat section on the pivot, and it is possible to install it upside down if you do not match up the curved section on my throttle pivot with the curved section of where the original factory pivot went. If it is installed upside down, the angle of the long rod that connects to the injecton pump will be at an improper angle and you'll have to re-install the throttle pivot the other way. Installation tip #2: To aid in installation of the bottom (left) bolt, it is suggested to first loosen the coolant pipe from the firewall (typically an 8mm bolt head from the factory). A set of wobble extensions and/or wobble sockets will help, as will a bit of paper towel around the 8mm bolt when installing (this prevents dropping of the bolts). This will allow for easier access and then you can re-tighten that coolant pipe after the throttle pivot bolts are installed.There is no need to over-tighten the two 8mm bolts that connect the pivot to the firewall. Snug and seated is good enough. These are not lug bolts and there's no need to crank down super hard on them. Installation tip #3: Using channel lock plyers will aid in the installation of the pedal linkage to the ball joint on the throttle pivot assembly. Don't just try to press it in without supporting the back side of it with the plyer or at least your finger as doing so will put unnecessary stress on the pivot assembly. In the even that you need to remove the linkage from the throttle pivot assembly for service, a simple gentle pry with wire cutters (dikes) behind the linkage will do the trick.
