NOTE: The Groundsmaster 3500- D hydraulic man-
ifold uses several zero leak plugs. These plugs have a
tapered sealing surface on the plug head that is de-
signed to resist vibration induced plug loosening. The
zero leak plugs also have an O- ring as a secondary
seal. If zero leak plug removal is necessary, lightly rap
the plug head using a punch and hammer before using
an allen wrench to remove the plug: the impact will allow
plug removal with less chance of damage to the socket
head of the plug.
For hydraulic manifold service procedures, refer to Hy-
draulic Manifold Service (Serial Numbers 240000601 to
313999999) in this section. Refer to Figure 99 for car-
tridge valve and plug installation torque.
