NOTE: ThePTOcontrolmanifoldsincludeseveralzero
leak NWD plugs. These plugs have a tapered sealing
surface on the plug head that is designed to resist vibra-
tion induced plug loosening. The zero leak plugs also
haveanO--ringasasecondary seal.Ifzero leakplugre-
moval is necessary, lightly rap the plug head using a
punch and hammer before using a wrench to remove
the plug: the impact will allow plug removal with less
chance of damage to the head of the plug. When instal-
ling plugs, refer to manifold illustration in Figure 81 for
plug installation torque.
