Lubricating Oil System Oil Tank Suction Strainers. (Refer to Figure K-35.)
The oil tank suction strainers are normally removed for replacement.
Removal.
a.
Remove the fuel system guard (page K-56).
b.
Completely drain the lubricating oil tank. Close the oil pump feed shutoff valve (handle
perpendicular to the lines).
NOTE
A small amount of oil will remain in the drained lubricating oil tank
because the suction strainers are higher than the bottom of the lubricating
oil tank. Use a suitable container to catch the remaining oil.
c.
Using a suitable container to catch any oil, loosen the hose clamp (1, Figure K-35)
securing the rubber oil line (2) to the outlet fitting on the suction strainer mounting base
(3) and disconnect the line from the fitting.
d.
Slowly unscrew the suction strainer mounting base (3), with the suction strainer element
(4) attached, from the lubricating oil tank (5). Use a suitable container to catch the
remaining oil in the lubricating oil tank (5). Remove the suction strainer mounting base
(3), with the suction strainer element (4) attached, and the suction strainer mounting
base o-ring (6). Discard the suction strainer mounting base o-ring (6).
e.
Unscrew the suction strainer element (4) from the mounting spigot on the suction
strainer mounting base (3).
Installation.
a.
Place Teflon tape on the threads of the mounting spigot on the suction strainer
mounting base (3, Figure K-35) and screw the replacement suction strainer element (4)
into the mounting spigot.
b.
Align a new suction strainer mounting base o-ring (6) on the suction strainer mounting
base (3) and screw the mounting base, with the suction strainer element (4) attached,
into the lubricating oil tank (5).
c.
Connect the rubber oil line (2) and hose clamp (1) to the outlet fitting on the suction
strainer mounting base (3). Tighten the hose clamp (1).
d.
Install the fuel system guard (page K-56).
