The snap ring is a simple and quick method to connect the thrust pad to the tommy screw. Instead of DIN 6311 a thrust pad GN 6311.1 can be used. In that case the tommy screw and the thrust pad have to be ordered separately. see also... • Thrust Pads GN 6311.1 → Page 1069 Hint for installation (Type F) The thrust pad has to be held at an angle allowing the circlip to drop to the bottom of its groove with the split end downwards. The thrust point is then offered up to the split end of the circlip at the lowest possible angle and pressed home.
