10. Note: The following pro-
cedure is only necessary
if a stud bolt (#49) has
been damaged and must
be replaced.
To remove
the manifold studs (#49),
place a stud nut (#50),
lock washer (#50A), and
second nut on each stud.
Tighten the nuts against
each other. Hold the front
nut with one wrench, and
remove the stud bolt by
turning the rear nut coun-
terclockwise with another
wrench. To reassemble,
turn the front stud bolt nut
clockwise.

(#29C) counterclockwise with a 13mm socket. Use a
steady torque to prevent ceramic plunger sleeve dam-
age. Loosen and remove the plunger bolt assembly
(#29C and #29D) and replace the seal washer (#29D).
11a. Inspect the crankcase
oil seals (#31) for evidence
of leaking. If there is oil on
the crankcase (#1) at the

must be replaced. The oil
seals are replaced after
removing the crosshead/
plunger assembly (#25) as
described below.
