Installation
The reverse order of operations will serve as a
guide for installation. In tightening the nut on
the fulcrum bolt, care should be exercised not to
draw the nut too tight. M o d e r a t e tightening of
the bolt is all that is necessary. See N o t e 8.

Installation
The reverse order of operations will serve as a
guide for installation of this unit.
W h e n installing the intermediate steering arm,
it is important to make sure that the ball bear-
ings are properly lubricated w i t h (G-12) wheel
bearing grease before installation. Also, when
tightening the nut on the fulcrum bolt, care
should be exercised to draw the nut up just
enough to remove all perceptible play i n the
bearings without causing them to bind.
4. Removal of Steering Universal Joints
Series 37-75 and 85
T o remove the universal joints and shaft used
in the series 37-75 and 85 steering column, pro-
ceed as follows:
1. Loosen the clamps at the upper universal
joint, the lower joint, and the steering worm
shaft.
2. Slide the shaft as far as possible up into the
upper universal j o i n t . T h i s will permit removing
the lower universal j o i n t from the steering gear
worm shaft, after which the upper end of the
shaft can be removed from the upper universal
joint.
T o reinstall, insert the shaft i n the upper u n i -
versal j o i n t and then attach the lower j o i n t to
the steering gear, reversing the procedure followed
in removal.
T i g h t e n first the clamp that holds the lower
j o i n t to the steering worm shaft. T h e n tighten
the clamp at the upper universal. T h i s clamp
fits into a notch in the upper end of the shaft.
F i n a l l y , tighten the clamp at the lower end of
the shaft. T h i s clamp tightens into a groove, so
that the shaft wilhbe adjustable for minor v a r i a -
tions.
T i g h t e n these clamps securely. Use a socket
wrench with a handle at least eight inches long,
and a p p l y it sturdily. Do_ not use an ordinary
open-end wrench as this will not permit the
application of sufficient force.
5. Removal of Steering Gear Arm
Series 37-75 and 85

ing gear arm (pitman arm) from the steering gear
of series 37-75 and 85 cars, if the complete steering-
