The Warden,

My daughter has the 240D in San Diego, and I am in Connecticut. So, I cannot photograph the parts or I would.

They are pretty easy to trace. There is a mechanism on the firewall that the throttle pedal is connected to, that turns the up and down linear motion of the pedal linkage to a rotational motion to deliver torque via a fore and aft oriented rod that goes from the firewall to the cluster of brackets and linkages suspended from the valve cover. At the end of this rod is the rubber/metal bonded part in question, which turns the rotational motion back into a linear up and down motion to move the throttle controls on the injection pump. There is also a connection to the cruise control and, on a 240D, the idle speed adjustment.

Good luck, Jim
