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
screws. Tighten main bearing screws
in stages to
a final torque of:
•
10 to 12 ft. lbs. (14.5 to 16.5 N·m).
Start in the center and work outward in a spiral
pattern.
Apply Nut Lock to crankcase flange screws. Install
crankcase flange screws and tighten to a torque
of 84 to 106 in. lbs. (9.5 to 12 N·m).
