INTRODUCTION
Spring pins
When fitting split socket elastic pins, ensure that the pin notch is positioned in the direction of the force required to
stress the pin.
Spiral spring pins do not require special positioning.
Front seals
Carefully check the metal rings, making sure that the
sealing surfaces show no signs of scoring, dents or wear
caused by ring pair misalignment or surface flatness
errors.
Even if only one of the rings is faulty, change the entire
seal.
Never pair a used ring with a new one or use different
pairs of rings.
To fit the seals, proceed as follows:
1. Eliminate any sharp edges or burr and carefully clean
the seats for the rubber rings.
2. Thoroughly clean the rings on the seals.
3. Insert each metal ring (2) on the respective rubber ring
(1) , as shown in the drawing, acting on the points in-
dicated by the arrows.
