Seals
The holes in flat seals must match up with the lubri-
cation channels in the relevant parts. If the seals
have to be made, choose a suitable type and thick-
ness of material and make cuts in the right places.
If seals are cut incorrectly, serious malfunctions can
result.
Seal rings/lip seals "SPY"
Coat the lips of "SPY" seal rings with oil before fit-
ting. Do not put grease on the seal rings unless they
are grease seals.
The main elements of a "SPY" seal ring are the cap
(1), the sealing part (2) and the spring collar (3).
In (
) you can see a single "SPY" seal ring. In the
cross section you can see the "flange" (4) and "pin"
(5), which sit on the outside and inside respectively
in a seal ring with a lip. With a few exceptions, the
pin on an oil ring with a lip faces the lubricant side.
Certain seal rings have an extra lip without a spring.
Securing and locking nuts and bolts
To prevent nuts and bolts working loose, use retain-
ing washers, lock plates and split pins. In addition to
these mechanical devices, use locking paste, e.g.
Loctite.
In order to work effectively, the locking plate has to
be bent down over the edge of the object. Bend the
other end up against one of the surfaces of the nut
or bolt head.
New locking plates must always be fitted in hous-
ings with moving parts. When fitting lock washers
on aluminium housings, insert a spring washer be-
tween the lock washer and the housing.
N
OTE
:
Retaining washers (Grower, star washer,
spring washer, etc.) must never be inserted under
nuts or screw heads that have to be tightened to a
specified torque.
N
OTE
:
When using locking paste such as Loctite,
the parts must always be degreased before the
paste is applied.
