PISTON CIRCLIP T20/3TA
Piston circlip for the T20 and 3TA, retains the gudgeon pin in the piston.
70-1767 is the piston circlip listed for the T20 and 3TA models, found in the crankshaft and connecting rods section of the parts book. It's a small retaining clip that keeps the gudgeon pin (wrist pin) located in the piston, stopping it from working sideways and scoring the cylinder bore.

This one also shows up under the older AA66 reference and the E1767 form, so if your parts book or an old parts bag has either of those numbers on it, it's the same piece.
Our records only show it turning up a couple of times in the catalog, so we don't have a lot more to add beyond what's here. Small part, but not one you want to reuse if it's tired or distorted — worth having a couple of spares on hand when you're doing piston work.
