18) Remove the pitching stopper.
19) Disconnect the fuel delivery hose (A), return
hose (B) and evaporation hose (C).
CAUTION:
 Disconnect the hose with its end wrapped
with cloth to prevent fuel from splashing.
 Catch fuel from the hose into container.
20) Support the engine with a lifting device and
wire ropes.21) Support the transmission with a garage jack.
CAUTION:
Before moving the engine away from transmis-
sion, check to be sure no work has been over-
looked. Doing this is very important in order to
facilitate re-installation and because the trans-
mission lowers under its own weight.
22) Separation of the engine and transmission.
(1) Remove the starter. REMOVAL, Starter.>
(2) Remove the bolts which hold upper side of
transmission to engine.
23) Install the ST to torque converter clutch case.
