BUSHING, T20 OIL PUMP DRIVE
Oil pump drive bushing for the Triumph T20, from the crankshaft/timing gears area of the engine.
This is the bushing for the oil pump drive on the Triumph T20, listed in the catalog under the number 70-4693 with the older alias E4693. It shows up in the parts book under the crankshaft, piston, and timing gears section, which puts it down in the timing-side area of the engine where the oil pump drive takes its motion off the timing gears.

A bushing like this lives between the moving drive component and its housing, taking up wear so the shaft stays located and turns true rather than wobbling in an oversize bore. Catalog appearances tie this part to 1963-1964, so that's what our records show for coverage.
If you're rebuilding the timing chest on a T20, this is a small, easy-to-overlook item — worth checking your old one for wear and ordering a fresh one line-side while you have things apart. Give us a call if you want to confirm this is the right number for what's on your bench.
