16. Remove the sump bolts using a 10mm wrench.
17. Carefully slide the sump off of the crank shaft. See
Figure 10.2.
18. Remove the camshaft. See Figure 10.3.
NOTE: Align the timing marks to allow easier
removal of the cam shaft and to help protect
the compression relief from damage.
NOTE: A paint pen can be used to fill in the timing
marks for better visibility.
19. Remove the valve tappets. See Figure 10.4.
NOTE: The valve tappets should be kept riding
against their original lobes. Once broken in,
switching the tappets to run on different cam
lobes will cause rapid tappet and cam wear.
Mark each tappet to identify which lobe it
was riding on.
