Most engines use an oil pan gasket. Optionally, RTV
sealant is used as a gasket between oil pan and
crankcase. When assembling oil pan, only use a gasket
if a gasket was removed. Likewise, if RTV was used,
only replace with RTV. Do Not use both. 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 Using outdated sealant can result in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.
2. Check to make sure that there are no nicks or burrs
on sealing surfaces of oil pan or crankcase.
3. Use a new gasket or apply RTV.
a. For an oil pan with a gasket:
1. Before installing gasket, check to make sure
O-ring is present in counter bore around dowel
pin.
b. For an oil pan with RTV:
1. Apply a 1.5 mm (1/16 in.) bead of sealant to
sealing surface of oil pan. Verify O-ring is
present.
4. Make sure end of governor cross shaft is lying
against bottom of cylinder #1 inside crankcase.
5. Install oil pan to crankcase. Carefully seat camshaft
and crankshaft into their mating bearings. Rotate
crankshaft slightly to help engage oil pump and
governor gear meshes.

holes.
2. Position stator aligning mounting holes so that leads
are at bottom, towards crankcase.
3. Install and torque screws to 6.2 N·m (55 in. lb.) for
new holes or 4.0 N·m (35 in. lb.) for used holes.
4. Route stator leads in crankcase channel, then install
backing plate. Secure with screws. Torque screws
