4. Determine if the outlet of the oil pump is open or
closed. See Figure 10-9. The open style pumps
require the use of a rubber seal between the
pump outlet and lower main bearing area. See
Figure 10-8. Some models use an open style seal
with an internal passage to feed oil to the lower
bearing. Some models use a closed seal without
an oil passage, and the crankshaft is crossed-
drilled for lower bearing lubrication. Both styles
of outlet seals are shown in Figure 10-9. If a new
6
seal is to be ordered, be sure it is the same style
5
as the one that was taken out. Lightly lubricate
the ends of the oil pump outlet seal with oil and
install in into the outlet of the oil pump. See
