Sealant Pattern and Torque Sequence
RTV sealant is used as a gasket between closure plate
and crankcase. Always use fresh sealant. Using
outdated sealant can result in leakage.

prepared. 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.
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 to 24.4 N·m (216 in. lb.) following
