CONNECTING ROD
Connecting rod for the Triumph engine bottom end, cataloged as 70-9911 (formerly E9911).
70-9911 is a connecting rod for the Triumph engine, showing up in the parts book under the CYLINDER HEAD, BARREL AND CRANKSHAFT figure. It also carries the earlier E9911 form, which is just the legacy way this same rod was numbered before the modern part number system took over.

A connecting rod links the piston to the crankshaft, transferring the up-and-down motion of the piston into the rotating motion that drives the engine. It's a part that takes a lot of stress over the life of an engine, so it's worth inspecting closely for straightness and wear at the bearing surfaces whenever the bottom end is apart.
Our catalog record for this one only shows a single appearance, tied to 1971. Beyond that we don't have more detail on model fitment, so give us a call and we'll confirm it matches your engine before you order.
