NOTE: A special gasket used between closure plate
and crankcase controls crankshaft endplay, no
shimming is required. Do not use RTV sealant in
place of gasket.
NOTE: Engines with fi rst generation balance weight:
Apply grease to outside fl at surfaces of balance
weight guide shoe. Position guide shoe so solid
end is toward crankshaft. Make sure guide shoe
stays in this position during step 2.
1. Make sure sealing surfaces of crankcase and
closure plate are clean, dry, and free of any nicks or
burrs. Install a new closure plate gasket onto
crankcase.
2. Ensure gasket, cover plate, and governor gear
assembly, have been properly assembled to closure
plate. Start closure plate onto crankcase. Be sure
guide shoe (models with First Generation Balance
Weight), is aligned with guide channel in closure
plate, and cam shafts and governor gear shaft are
aligned with their mating bearing surfaces. As
closure plate is lowered into fi nal position, rotate
crankshaft slightly to help engage governor gear.
3. Install screws securing closure plate to crankcase,
with any clamps for wiring harness and sheathed
RFI suppression spark plug lead (#5 location, if
equipped). If wiring harness was separated from
closure plate, route harness through clamps and slot
in closure plate. Close clamps to retain harness.
4. Torque closure plate fasteners to 24.5 N·m
(216 in. lb.) using sequence shown.
