9) Check surfaces of plunger
(16). Damaged surfaces
cause accelerated seal
wear. Deposits of all kinds
must be removed from the
plungers.
11) If oil leaks under under the
plunger (16), the oil seals
(19) need to be replaced.
Remove oil plug (5) and
drain oil. With the valve
casing (26) and seal case
(20) removed (ref. instruc-
tions #5 & 6), and plunger
disassembled (ref. #10),
carefully pry out the oil
seal with a flat screwdriver
and replace it with a new
one. Make sure that the oil
seal groove faces inward
towards the oil.
NOTE:
Be careful not
to score the crankcase
guides where the oil seal
sits and where the plunger
base (16A) moves through
the crankcase (1).
10) If the plunger pipe (16B), is
damaged or worn, remove
tension screw (16D) and
plunger pipe (16B). Check
and clean plunger surface
(16A) and check flinger
(16H). Cover thread of
tension screw (16D) with a
thin film of Loctite 243 and
tighten carefully to 22 ft.-
lbs. (30NM).
