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.
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.
Lightly coat the upper and lower crankcase head
flange surfaces with a thin layer of
Gel-Seal II .
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.
Install main bearing screws and nuts finger tight,
no more than 60 in. lbs. (7 N·m).
When the crankcase is seated, install and firmly
seat both crankcase taper pins.
Tighten main bearing screws and nuts in stages
to a final torque of:
•
Screws – 48 to 53 ft. lbs. (65 to 72 N·m)
•
Nuts – 38 to 42 ft. lbs. (52 to 57 N·m)
Start in the center and work outward in a spiral
pattern.
