4. Lubrication
The piston should be relubricated every 15,000 miles with one
ounce of Genuine Hudson Shock Absorber Fluid. This can most
readily be injected by removing the piston rod guard and placing
the nozzle of an oil can in the slot in the piston rod as shown in
Figure 905, with the engine running and the accelerator de-
pressed so that the clutch is engaged. Release the accelerator
pedal and squirt the oil into the slot as the clutch is disengaging.
The forward motion of the piston will draw the oil into the
cylinder.
After the oil has been injected, remove clevis pin (I) and work
the piston back and forth while rotating it to distribute the oil.
Before reinserting the clevis pin, turn the piston one-half turn so
that the portion of the packing which has been resting on the
bottom will be on top. This will tend to distribute the wear on
the packing.
5. Piston Rod Adjustment-1937
Adjust piston rod clevis (G), (Figure 904) so that the center
of clevis pin (I) is exactly 1-7/8" from the rear end of the
piston rod (do not measure to lock nut).
This adjustment is important as it determines the cushion
point from which gradual engagement of the clutch begins.
This adjustment may give slightly soft engagement which
will require the yoke being screwed out to allow quicker
clutch engagement. This, however, should not be done until
other preliminary adjustments are made (paragraphs 6, 7 and
8).
6. Centering Piston Travel in Cylinder-1937
Push accelerator control valve plunger (C) forward with
engine dead and pull piston rod backward to limit. Clearance
between front end of slot in clevis on rod (K) and clevis pin
should be 1/8" as shown (Figure 904).
