ABSTRACT:
A drive line, such as is used in agricultural equipment to drive various components, includes a rotating driveshaft that is connected to a driven shaft through a slip clutch that is coaxial with the two shafts and has clutch components that extend radially outwardly of the drive and driven shafts. A tubular shaft shield is coaxially and rotatably mounted around the drive shaft adjacent the clutch and includes an element with an annular external groove adjacent the clutch. A second tubular shield is coaxially mounted on the shaft shield and includes a bell-shaped housing that normally encloses the clutch, the outer shield having an internal annular groove opposite the external groove and being rotatable on and axially shiftable relative to the shaft shield. A plastic snap ring is mounted in the internal groove and seats in the external groove to axially lock the outer shield to the inner shield, the snap ring expanding upon the exertion of a predetermined amount of axial force on the outer shield to unseat from the external groove and permit axial shifting of the outer shield to a position wherein it provides access to the clutch components.
