2.6 PRACTICAL HINTS

A) Fitting snap rings
One side of the "Benzing" snap rings (1) has a
rounded edge and the other a sharp edge.
For maximum grip the rounded part needs to be
facing towards the element to be held (2), with the
sharp edges on the outside.
B) Joint pivot pins
There are a large number of pivot pins, usually con-
nected to rods, that need to be able to move in var-
ious directions.
A typical situation has the pin (3) fixed by a self-
locking nut (4) with two anti-friction washers (5) in
between the pin (3) and the support element, and
between this and the nut (4).
Since these are joints, the nut must never be tight-
ened completely but only so much that it can
ensure the free rotational movement of the pin on its
axis without, however, creating excessive free play
which could result in the parts concerned becoming
misaligned and failing to work correctly.
C) Crown fasteners
Some pin ends (6) are secured by crown fasteners
(7). During dismantling, these fasteners are always
damaged and lose their hold, so they should never
be reused.
On assembly, make sure it is inserted in the right
direction and push the fastener (7) onto the pin
using a pipe or socket spanner (8) with the right
diameter, so that it can be fitted without deforming
the fastener "crown".
A deformed fastener should always be replaced.
