Felt washer
A felt washer (57-1979) used as an oil-retaining seal on a shaft in the gearbox or chaincase area.
This is a felt washer, catalog number 57-1979, also listed in older books under the T1979 designation. The catalog places it in the gearbox shafts and gears area as well as the chaincase and chains section, which tells us it's doing sealing or oil-retention duty around a shaft where it passes through a cover or housing.

Felt washers like this one work as simple wick-type seals, soaking up a bit of oil and keeping it from running out along a shaft while still letting some lubrication through. It's a small, inexpensive item to have on hand when you're rebuilding the area it lives in, since felt breaks down and hardens with age.
Our records show this one appearing across a small number of catalog listings tied to 1965. If you're not sure which shaft or cover it seals on your machine, give us a call and we'll help confirm before you order.
