9) Check surfaces of plunger
(16). Damaged surfaces
cause accelerated seal
wear. Deposits of all kinds
must be removed from the
plungers.
IMPORTANT! Plunger
surfaces are not to be
damaged. If there are
lime deposits in the
pump, care must be
taken that the drip-return
bore in parts (25) and
(26) ensure trouble-free
drip-return.
10) If the plunger pipe (16B),
or oil seal (19) is worn, re-
move tension screw (16D)
and remove along with
plunger pipe (16B). Check
and clean plunger surface
(16A), check oil scraper
(16H). Remove the seal
case (20) and, if neces-
sary, replace oil seals with
seal lips facing crankcase
(1).Cover thread of ten-
sion screw (16D) with a
thin film of Loctite and
tighten carefully to 221-
265 in-lbs (25-30NM).
IMPORTANT!
Care must be
taken that glue does not get
between the plunger pipe
(16B) and plunger base (16A).
The plunger pipe should not
be strained by eccentric
tightening of the tension
screw or through damage to
front surface of plunger,
otherwise it is liable to
fracture
