I realize you have a 93, B5.9. This is a cut and paste from the Dodge Shop Manual for a 2003 B5.9 engine, oil pan removal. Hopefully it will give you some insight ? I have no idea why Dodge says the flywheel has to be removed ?

OIL PAN
REMOVAL
(1) Disconnect the battery negative cables.
(2) Install engine support fixture # 8534.
(3) Raise vehicle on hoist.
(4) Disconnect starter cables from starter motor.
(5) Remove starter motor (Refer to 8 - ELECTRI-
CAL/STARTING/STARTER MOTOR - REMOVAL)
and transmission adapter plate assembly.
(6) Remove transmission and transfer case (if
equipped).
(7) Remove flywheel or flexplate.
(8) Remove the transmission adapter plate.
WARNING: HOT OIL CAN CAUSE PERSONAL
INJURY.
(9) Drain the engine oil (Refer to 9 - ENGINE/LU-
BRICATION/OIL - STANDARD PROCEDURE).
(10) Install the oil pan drain plug if sealing sur-
face is not damaged and tighten to 50 N·m (57 ft.
lbs.) torque.
(11) Remove oil pan bolts, break the pan to block
seal, and lower pan slightly and remove oil suction
tube fasteners.
(12) Remove oil pan and suction tube.
CLEANING
Remove all gasket material from the oil pan and
cylinder block sealing surfaces. Extra effort may be
required around T-joint areas. Clean oil pan and
flush suction tube with a suitable solvent.
INSPECTION
Inspect the oil pan, suction tube, and tube braces
for cracks and damage. Replace any defective compo-
nent. Inspect the oil drain plug and drain hole
threads. Inspect the oil pan sealing surface for
straightness. Repair any minor imperfections with a
ball-peen hammer. Do not attempt to repair an oil
pan by welding.

ing and pan rail/rear seal retainer with sealant. Use
Mopar Silicone Rubber Adhesive Sealant or equiva-
lent.

into place. Using a new tube to block gasket, install
and tighten the suction tube bolts by hand. Starting
with the oil pump inlet bolts, tighten the bolts to 24
N·m (18 ft. lbs.) torque. Tighten the remaining tube
brace bolts to 43 N·m (32 ft. lbs.) torque.
(3) Starting in the center and working outward,
tighten the oil pan bolts to 28 N·m (21 ft. lbs.)
torque.
(4) Install the flywheel housing assembly with the
starter motor attached and tighten bolts to 77 N·m
(57 ft. lbs.) torque.
