Hudson 1953 Super Jet, Mechanical Procedure Manual

Page: 42 / 156

Mount a dial indicator on the block with the
indicator pin against the crankshaft rear flange.
Pry the shaft in the opposite direction to its limit
and note the total amount of end play shown on
the dial indicator.
3. Install connecting rods to crankshaft, torque
connecting rod bolt nuts t o 40-45 foot pounds
and install palnuts.
4. Install wick packing into the vertical holes (1)
and (2), Figure 18, in front and rear caps first,
then into the horizontal holes (3) of the front
bearing cap.
FIGURE 18
NOTE: When installing a new packing, use a
blunt punch with a diameter slightly smaller
than the packing groove. Punch end should be
not shorter than 4 inches to insure seal bot-
toming.
Packing must be compressed until it bottoms
in the packing grooves, and enough packing in-
stalled to make a solid seal flush with front face
and bottom face of the bearing caps.
5. Clean all traces of the old front support gasket
from front face of cylinder block. Install a new
gasket and the front support plate.
6. Install new oil pan gaskets and oil pan. Tighten
all screws to 15-20 foot pounds.
TIMING CHAIN AND SPROCKETS
The timing chain is non-adjustable. To check
for chain and sprocket wear, rotate the crankshaft
until the upper span of the chain is tight. Deflection
of more than 3/4" from a straight line at the lower
span indicates a worn chain that should be re-
placed. Check the sprockets for excessive wear
conditions. If considerably worn, replace the
sprockets.
INSTALLATION
1. Align keyway in crankshaft sprocket with key
in crankshaft.
2. Using J-5369, Installer, and with a hammer
drive crankshaft gear on until it seats against
shoulder on crankshaft, Figure 19.
FIGURE 19
NOTE: After the crankshaft sprocket is insta
lle d, rotate the crankshaft until the key way is
in a vertical position at the top, Figure 20. The
timing mark on the crankshaft sprocket will be
approximately 60° from the vertical. (This
places the #1 piston at top dead center in firing
position.)
The timing chain has two punched side links 7
full lengths apart, shown as (A), Figure 20.
3. Mount the timing chain on the camshaft
sprocket with the marks matched on the
sprocket and chain.
4. In s t all the timing chain over the crankshaft
sprocket with the chain and sprocket timing
marks matched.
5. Rotate the camshaft until the camshaft screw
holes match those in the camshaft sprocket and
install the three mounting cap screws.
6. Install safety wire through the three cap screw
heads.
