POWERHEAD ASSEMBLY

IMPORTANT:
If a new screw is used, it must be
installed as above. Then, it must be removed, re-
lubricated, and installed again.
Loosen forcing screw and remove the frame.
Test at least three corners of the rod and cap joint
with a pick. Joint must be smooth with no step.
Crankcase Assembly
Thoroughly clean and degrease the mating
flanges of the crankcase and cylinder block with a
non-petroleum based solvent, such as isopropyl
alcohol or acetone, and let air dry.
IMPORTANT:
DO NOT allow solvent to get on
internal components. Clean only the mating
flanges.
Apply
Gasket Sealing Compound
to lower oil seal
groove in crankcase. DO NOT put any sealer in
upper seal groove.
Use a small brush with a tapping motion to apply a
thin, even coat of
Gel-Seal II
sealant to the crank-
case mating flange. The sealer must not come
within 1/4 in. (6.4 mm) of bearings.
IMPORTANT:
Gel-Seal II
has a shelf life of at
least one year when stored at room temperature.
Test the
Gel-Seal II
or replace it if the age of the
tube cannot be determined. Using old
Gel-Seal II
could cause crankcase air leaks.
IMPORTANT:
The use of
Locquic Primer
is
NOT recommended. If primer is used, crankcase
halves must be assembled and tightened within
ten minutes after the
Gel-Seal II
has been applied.
Lower the crankcase into place. Make sure that
upper oil seal and lower seal housing are seated
in grooves.
Apply outboard lubricant to the main bearing
studs. Install nuts and washers finger tight, no
more than 60 in. lbs. (7 N·m).
