Install Closure Plate Assembly
A
A RTV Must Be All Around O-ring Groove.
RTV sealant is used as a gasket between closure plate
and crankcase. Refer to Tools and Aids for a listing of
approved sealants. Always use fresh sealant. Using
outdated sealant can result in leakage.
1. Be sure sealing surfaces have been cleaned and
prepared as described at beginning of Disassembly/
Inspection and Service. Install a new O-ring in
closure plate.
2. Check to make sure there are no nicks or burrs on
sealing surfaces of closure plate or crankcase.
3. Apply a 1.5 mm (1/16 in.) bead of sealant to sealing
surface of closure plate. Verify O-ring is present. See
sealant pattern.
4. Make sure end of governor cross shaft is lying
against bottom of cylinder 1 inside crankcase.
5. Install closure plate to crankcase. Carefully seat
camshaft and crankshaft into their mating bearings.
Rotate crankshaft slightly to help engage oil pump
and governor gear meshes.
6. Install screws securing closure plate to crankcase.
Torque fasteners in sequence shown to 25.6 N·m

sealant patch. This screw is typically installed in #10
hole shown. Reapply pipe sealant with Tefl on

™
PST
®
Thread Sealant or equivalent) to stator mounting
holes.
2. Position stator aligning mounting holes so leads are
at bottom, towards crankcase.
3. Install and torque screws to 6.2 N·m (55 in. lb.) into
new holes or 4.0 N·m (35 in. lb.) into used holes.
4. Route stator leads in crankcase channel, then install
backing plate. Secure using screws. Torque screws
to 10.7 N·m (95 in. lb.) into new holes or 7.3 N·m (65
in. lb.) into used holes.
