WRIST PIN BUSHING 650 TRIUMPH
Small end / wrist pin bushing for the Triumph 650 twin connecting rod, sold as a pair, PN 70-1511.
This is the small end bushing for the connecting rod on Triumph's 650 unit twin, catalogued as 70-1511 and known in the older parts books under the E1511 number. It sits at the top of the connecting rod, where the wrist pin (gudgeon pin) passes through to link the rod to the piston, and it's the bearing surface that takes the wear from that pin's motion.

It shows up in the crankshaft and connecting rod section of the parts books, and it's listed across catalog entries running from the mid-60s into the early 70s for the 650 twins. Because it's a wear item at a high-load junction, this is the kind of part that gets checked and often replaced during a bottom-end rebuild rather than reused.
Our records show this one sold as a pair of bushings. If you're rebuilding a set of rods, plan on two per rod set, and give us a call if you want to confirm exactly which rods and years this fits before you order.
