ALIGNING ROD WITH PISTON
A quick check of a piston and connecting rod
assembly can be made for both twist and b end with-
out disassembling the piston from the connecting rod.
1. Mount the connecting rod and piston assemby on
the alignment fixture and set the piston in line with
the connecting rod.
2. Place the "V" block on the piston skirt. If both pins
on the "V" block contact the face plate, then the
rod is straight.
3. With the "V" block on the piston skirt and the pins
against the face plate, rotate the piston first in one
direction and then in the other. If the pins on the
"V" block contact the face plate at all points, the
connecting rod is not twisted. If one pin leaves the
face plate while being rotated in one direction and
the other while being rotated in the opposite direc-
tion, the rod is twisted.
To straighten a bent or twisted rod, use two
Bending Bars HM-3-R, one to hold the rod and
the other to bend or twist the rod into proper
alignment. Always bend beyond the true alignment
position and then bend back straight to relieve the
stress that results from the bending operation. If
the stress is not relieved, the rod will not hold its
alignment after installation in the engine.

CRANKSHAFT

The crankshaft can be removed from the engine
without removing the engine from the car. Howev-
er, it is more practical to remove the engine when
replacing the crankshaft.
ENGINE REMOVAL
NOTE: After removing the transmission the
engine can be removed as one unit with the
electrical units and carburetor attached.
1. Re move the two hood hinge bolts from each
side at the rear of the hood.
2. Lift and remove hood.
3. Drain cooling system, open drain at bottom right
side of radiator. Remove drain plug from left
rear side of the engine.
4. Disconnect the throttle linkage.
5. Disconnect the fuel line at the junction of the
fuel pump flexible hose and steel gas line.
6. Remove the bolts from the exhaust pipe to the
exhaust manifold flange.
7. Remove the radiator hoses.
8. Disconnect the remote control rods at the
transmission.
9. Disconnect the wire at the starter motor and
remove the cable from the battery.
10. Disconnect the water temperature gauge wire
from the side of the cylinder head.
11. Disconnect the oil gauge light wire.
12. Disconnect the vacuum tube from the wind-
shield wiper motor.
13. Remove the two generator lead wires.
14. Disconnect the primary coil wire.
15. Remove slotted head screw holding the
breather tube to the rear tappet cover.
16. Remove the bolt from the bracket attaching the
breather to the engine end plate.
17. Remove the nine hexagon head self-tapping
screws holding the hood lock lower support
panel to the fender tie panel and remove the
support panel.
