MECHANICAL PROCEDURE MANUAL
4. Pump piston back and forth until shock absorber is
COMPLETELY empty of fluid.
5. Clamp fluid plug base end in vise, with filler hole on top,
and collapse to shortest length.
6. Be sure shock absorber is in horizontal position (or below)
to eliminate possibility of air pockets.
7. Screw filling cup (Figure 1903) into fluid filler hole. Pour
correct amount of shock absorber fluid into filling cup, as desig-
nated on chart below.
8. Pull shock out to fully extended position. This will suck
part of the fluid into shock absorber. Work piston back and forth
using short quick strokes until ALL FLUID is worked into
shock absorber.
9. Install new gasket and replace filler plug (P) making sure
that filler plug is tightly seated.
The correct quantity of Genuine Hudson Shock Absorber
fluid required for refilling is as follows:
Model Front Rear
1934 Hudson, 116" W/B 4¾ oz. 5 oz.
122" W/B 4¾ oz. 5¼ oz
1935 Hudson 8 4¾ oz. 5¼ oz
1935 Hudson 6 4¾ oz. 5¼ oz
1936 Hudson 8 4¾ oz.. 5¼ oz
1936 Hudson 6 4¾ oz. 5¼ oz
1937 Hudson 8 6¼ oz 6¼ oz
1937 Hudson 6 6¼ oz. 6¼ oz
The quantities given are fluid ounces. Do not measure oil by
weight as this will over-fill the units and cause damage to the oil
seals.
Rebuilding 1934-36 Shock Absorbers
1. Remove shock absorber from car and thoroughly clean
away all dirt.
2. Pull out shock absorber to fully extended position.
3. Remove filler plug (13), Figure 1904 and filler plug gasket.
4. Pump piston back and forth until shock absorber is
COMPLETELY empty of fluid.
5. Make sure the pin (11) in the upper forging (Figure 1904)
is flush, or nearly so, with top surface.
6. Collapse shock absorber and turn slowly until pin in
upper forging locks in slot, in top guide, then continue
turning to left until top unit can be lifted out.
7. Clamp top eye in vise. DO NOT CLAMP TUBE IN
VISE.
8. Remove nut holding piston on piston rod using Tool
(A-497*) and remove piston (2).
9. Valve plate (3), valve disc (8), spring and guide (10)
can be removed in order.
10. Remove piston rod guide and oil seal assembly.
Reassembling
1. Wash all parts of the shock absorber carefully in
gasoline and blow dry, paying particular attention to the
