Reassembly
6. Install the ten hex flange screws securing the oil
pan to the crankcase. Torque the fasteners in the
sequence shown in Figure 11-18 to 24.4 N·m
(216 in. lb). On some engines one of the ten
mounting screws is plated. The plated screw is
typically installed in the #6 hole shown in Figure
11-18.

Install Stator and Backing Plates
1. Apply pipe sealant with Teflon
®
(Loctite
®
No.
59241 or equivalent) to the stator mounting holes.
2. Position the stator aligning the mounting holes so
that the leads are at the bottom, towards the
crankcase.
3. Install and torque the two hex flange screws to
6.2 N·m (55 in. lb.). See Figure 11-20.
Install Oil Pan Assembly
RTV sealant is used as a gasket between the oil pan
and the crankcase on CV17-23 engines. CV25-750
engines use an oil pan gasket. Refer to Section 2 for a
listing of approved sealants. Always use fresh sealant.
Using outdated sealant can result in leakage.
1. Be sure the sealing surfaces have been cleaned
and prepared as described at the beginning of
Section 10 or in Service Bulletin 252.
2. Check to make sure that there are no nicks or
burrs on the sealing surfaces of the oil pan or
crankcase.
3. Apply a 1.5 mm (1/16 in.) bead of sealant to the
sealing surface of the oil pan on CV17-23 engines.
See Figure 11-17 for the sealant pattern. On
CV25-750 engines use a new gasket. Before
installing the gasket, check the dowel pin on the
oil filter side of the crankcase. If a “split” style
dowel pin is contained, replace it with a closed
seam style pin provided with the new gasket.

4. Make sure the end of the governor cross shaft is
lying against the bottom of cylinder 1 inside the
crankcase. See Figure 11-13.
5. Install the oil pan to the crankcase. Carefully seat
the camshaft and the crankshaft into their mating
bearings. Rotate the crankshaft slightly to help
engage the oil pump and governor gear meshes.
Apply 1.5 mm (1/16 in.)
bead of sealant.
