1999 SUBARU LEGACY low oil pressure

17) Remove pitching stopper.
G2M0295
18) Disconnect fuel delivery hose, return hose and
evaporation hose.
CAUTION:
IDisconnect hose with its end wrapped with
cloth to prevent fuel from splashing.
ICatch fuel from hose into container.
B2M0336
19) Support engine with a lifting device and wire
ropes.
G2M0297
20) Support transmission with a garage jack.
CAUTION:
Before moving engine away from transmission,
check to be sure no work has been overlooked.
Doing this is very important in order to facili-
tate re-installation and because transmission
lowers under its own weight.
G2M0298
21) Remove bolts which hold upper side of trans-
mission to engine.
B2M2794
22) Remove engine from vehicle
(1) Slightly raise engine.
(2) Raise transmission with garage jack.
(3) Move engine horizontally until mainshaft is
withdrawn from clutch cover.
(4) Slowly move engine away from engine
compartment.
CAUTION:
Be careful not to damage adjacent parts or
body panels with crank pulley, oil pressure
gauge, etc.
