The following components will remain intact dur-
ing carrier removal: Gear cover, gears, balance shafts
and the rear cover (Fig. 118).
(1) Drain engine oil.
(2) Remove the oil pan and pick-up tube (Refer to

INSTALLATION
BALANCE SHAFT INSTALLATION/TIMING
Balance shaft and carrier assembly installation is
the reverse of the removal procedure. During instal-
lation crankshaft-to-balance shaft timing must
be established. Refer to Timing procedure in
this section.
(1) With balance shafts installed in carrier (Fig.
118) position carrier on crankcase and install four
attaching bolts and tighten to 54 N·m (40 ft. lbs.).
(2) Turn balance shafts until both shaft key ways
are up, parallel to vertical centerline of engine.
Install short hub drive gear on sprocket driven shaft
and long hub gear on gear driven shaft. After instal-
lation gear and balance shaft keyways must be up
with gear timing marks meshed as shown in (Fig.
123).
