however, a decrease in caster, if spindle pins are not loose in the
bushings, is not detrimental to steering unless an actual reverse
camber exists.
23. Turn the wheels back to the straight ahead position and
reset the jiffy gauge as in paragraph 18, Figure 1801.
24. Turn the wheels to the right until the pointer on the left turn
plate is at 25°, level the gauge with the adjusting screw and take
the reading of the pointer on the upper scale.
25. Turn the left wheel 25° to the left and level the gauge and
take the reading on the upper scale (Figure 1804). If both read-
ings are on the same side of zero, subtract the one from the other
to get the caster angle of the left wheel. If the two readings are
on opposite sides of zero, add them to get the caster angle.
Readings toward the wheel are positive and away from the
wheel are negative caster angle.
26. Repeat operations 18 to 25 inclusive on the right wheel,
turning the wheels so that the pointer of the right turn plate reads
25° to the right for the first caster reading and 25° to the left for
the second caster reading.
The correct caster settings are as follows:
Terraplane Hudson Six Hudson Eight
1934 2½°—3½° 2½°—3½° 2° —2½°
1935 3¼°—3¾° 4º —4½° 4° —4½°
1936 2° —2½° 2½ —2½° 2½ —2½°
1937 1° —2° 1° —2° 1º —2º

27. Insert caster wedges between the axle and spring with
the thick end forward to reduce caster and the thick end to the
rear to increase caster.
28. Remove cotter key from bolt (D), Figure 1805, which
attaches torque arm to axle yoke and loosen nut.
29. Remove cap screw (E) and lock.
30. Add shims (F) to reduce caster.
Remove shims (F) to increase caster.
Addition or removal of .060" of shim thickness will change
the caster approximately 1°.
31. Replace cap screw (E) and lock.
32. Tighten bolt nut (D) and insert cotter key.

33. Remove bolts (1) and locks (2).
34. To reduce caster increase thickness of shims at (3) and
(or) reduce thickness at (4). To increase caster decrease thick-
ness of shims at (3) and (or) increase thickness at (4).
35. Install bolts (1) and locks (2).
36. Repeat operation 24 to 26 inclusive to recheck caster.
37. Remove jiffy gauge and replace spindle washer and nut,
adjust bearing and insert cotter key.
38. Turn left wheel to left 200. Right wheel as indicated by
point on turning angle plate should be (17¾°) to left.
