Seals
The holes in flat seals must match up with the lubrication
4
channels in the relevant parts. If the seals have to be
made, choose a suitable type and thickness of material
5
and make cuts in the right places. If seals are cut incor-
rectly, serious malfunctions can result.
Seal rings/lip seals ("SPY")
Coat the lips of "SPY" seal rings with oil before fitting. Do
3
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).
2
In (Fig. 4) 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
1
lip faces the lubricant side. Certain seal rings have an
extra lip without a spring.
