Description :

WARNING: Operating a turntable with a missing Steuerpimpel will damage the
    lever that it mates to, even if it appears to be working properly.
    
Replacement
    steuerpimpels for Dual turntables.
    For Dual 601, 620, 621, 622, 630, 701, 1220, 1222, 1224, 1225, 1226,  
    1245, 1249, 2225... and others.
Note the
gap between the bottom of the Steuerpimpel Glider Pad and the brass
looking sleeve. The silver colored stem or post between these parts
moves up and down with the mechanism to create the Start and Stop
functions. That 1/8” travel (approx.) is permitted by this properly
sized Steuerpimpel Glider Pad.
Best I can measure is: 5 mm
diameter (about 3/16"), 7 mm tall (about 1/4"). with a smoothly rounded
top. The hole in the bottom is bigger than a 5/64" drill and snug on a
3/32"drill. It appears to be a 4 mm deep. It is a relatively soft &
squeezable rubber part. Softer than a pencil eraser.
It's a miniature part with maximum impact and importance!
