RTV sealant is used as a gasket between oil pan and
crankcase on CV17-23 engines. CV25-750 engines use
an oil pan gasket. 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outdated sealant can result in leakage.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. Install a new O-ring in oil pan.
2. Check to make sure that there are no nicks or burrs
on sealing surfaces of oil pan or crankcase.
3. Apply a 1.5 mm (1/16 in.) bead of sealant to sealing
surface of oil pan on CV17-23 engines. CV25-750
engines use a new gasket. Before installing gasket,
check dowel pin on oil lter side of crankcase. If a
split style dowel pin is contained, replace it with a
closed seam style pin provided with new gasket.
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.
6. Install screws securing oil pan to crankcase. Torque
fasteners to 24.4 N·m (216 in. lb) following
sequence. On some engines one mounting screw is
plated. Plated screw is typically installed in hole
location 6.
