CLUTCH SPRING T15/T20
Clutch spring for the Triumph T15/T20, superseded by 57-2727.
This is the clutch spring listed for the T15 and T20 in the Triumph parts records, part number 57-1742. It's a small spring, part of a set that lives inside the clutch assembly, providing the pressure that keeps the clutch plates engaged so power gets transmitted from the engine to the gearbox.

Our record on this one is brief and doesn't give us dimensions, quantity fitted, or additional model detail beyond the T15/T20 reference already in the catalog description. If you're working on a Cub-family machine and need this spring, give us a call to confirm you've got the right one for your particular clutch setup before ordering.
Note that Triumph's records show this part was superseded by 57-2727, so if your parts book or an older reference lists 57-1742, that's the same spring under a newer number.
