Shock absorber spider

Clutch shock absorber spider, catalog part 57-1721 (also listed as T1721).

PN · 57-1721

57-1721 is the shock absorber spider that lives in the clutch assembly. It appears in the clutch section of the parts books, and its job is tied to cushioning the drive as the clutch takes up load. Older parts books list this same piece under the T1721 number, so if that's what's stamped or printed in your book, it's the same physical part.
