4.5.6 Flywheel
Figure 48
– Removing Flywheel
Once all 6 cap screws have been removed the flywheel can be levered off of the crankshaft: note the
leverage points in Figure 48, where 2 large screwdrivers are placed under the flywheel on the tops of
opposing timing case cap screws and then moved evenly up to provide leverage to remove the flywheel
from the crankshaft.
4.5.7 Timing Case
Remove the cap screws from the timing case and remove the case from the engine mount plate
– there
are machined recesses in each side of the timing case, as shown circled in Figure 49, that are designed
to allow a screwdriver tip to be inserted and twisted to break the gasket seal and free the timing case.
A soft hammer may be used to help.
Remove the distributor drive gears and shafts. Drive the oil seal out of the timing case.
