Piston rod seal type TICLA
is of compact design with integrated
support ring. It has an inner sealing lip against the piston rod and
an outer sealing lip which seals with press fit against the cylinder
head. An intermediate bead between the sealing lips provides ax-
ial fixation
The bead has recesses to admit hydraulic pressure on both outer
and inner sealing lips.
Even the smallest amount of damage to the sealing lips can
cause a major leakage. Check the sealing lips by carefully feeling
around the seal with a finger nail.
Use a screwdriver to remove the seal, see illustration. Lever out
and twist up the seal. It is extremely important that the screwdriv-
er is inserted between the inner sealing lip and the intermediate
bead so that it cannot touch and thereby damage any sealing sur-
face. A score from a screwdriver on the sealing surface will have
a disastrous effect and cause major leakage.
