a. Description
PUMP
PRESSURE IN
The power steering gear ( F i g s . 13 a n d 14) consists
of a gear housing containing a gear shaft w i t h
sector gear, a power p i s t o n w i t h gear teeth milled
i n t o t h e side of the p i s t o n is i n constant mesh w i t h
t h e gear shaft sector and a w o r m s h a f t connects t h e
steering wheel t o t h e power piston. The w o r m shaft
is geared t o the piston t h r o u g h a r e c i r c u l a t i n g ball
contact.
b. Operation
I n t h i s explanation o f operation (as viewed i n t h e
f o l l o w i n g i l l u s t r a t i o n s ) the l e f t end of t h e steering
gear means the lower end and t h e r i g h t end means
the upper end o f t h e steering gear. D i r e c t i o n of o i l
flow w i l l also be described as flowing t o left or r i g h t
as shown i n the f o l l o w i n g i l l u s t r a t i o n s .
W h e n t h e car is i n t h e straight-ahead direction,
the steering valve is i n t h e n e u t r a l (center) position
and o i l flow t h r o u g h b o t h of t h e grooves i n t h e
steering valve body is equal, since i n t h e n e u t r a l
position ( F i g . 15), the t w o lands o f t h e steering valve
are centered i n t h e grooves of the valve body. The
left oil passage directs i t s oil where i t contacts t h e
r i g h t (upper) end o f t h e power p i s t o n and across
i n t o the r i g h t reaction chamber. P a r t o f t h i s o i l is
forced around the grooves o f t h e w o r m shaft, inside
t h e piston and around t h e r e c i r c u l a t i n g balls, t o
the hollow area between t h e left ( l o w e r ) end of t h e
w o r m shaft and t h e l e f t (lower) end o f the power
piston. Pressure on t h e end of t h e w o r m shaft is
balanced b y the pressure against t h e area o f the
w o r m shaft balancing r i n g .
A t t h e same t i m e , oil f r o m the r i g h t groove i n t h e

steering pump t h r o u g h the enlarged orifice and
t h r o u g h t h e o i l gallery t o the left t u r n power chamber of t h e piston ( F i g . 1 8 ) . Since the supply of o i l t o
the left (lower side) ( r i g h t t u r n chamber) of t h e pist o n has been cut off b y movement of the steering
valve, a force o f unbalance on t h e p i s t o n exists and
i t is pushed t o the left. I t s linear movement is t r a n s lated i n t o r o t a t i o n of the cross shaft sector gear
(Figs. 13 and 14) and subsequently t h r o u g h the
steering linkage t o the f r o n t wheels.
I n t h e reaction area of t h e steering u n i t another
action takes place simultaneously as the wheel is
t u r n e d to the left. The r e s t r a i n i n g force of the react i o n s p r i n g m u s t be overcome before t h e center race
can move t o t h e r i g h t . , The force o f t h e reaction
s p r i n g provides positive r e t u r n a b i l i t y t o t h e u n i t . A t
t h e i n s t a n t w h e n power assistance is no longer desired b y the d r i v e r , t h e reaction s p r i n g and t h e opera t i n g o i l pressure move the center t h r u s t bearing
race and t h e steering spool valve back t o t h e i r neut r a l (center) positions. E q u a l o i l pressures t h e n are
directed to b o t h sides of the pow er piston and power
assist ceases immediately. The n a t u r a l effect of the
f r o n t wheel caster and the steering axis i n c l i n a t i o n
then r e t u r n s the wheels to t h e i r straight-ahead
position.

W h e n a r i g h t t u r n is made, a l l of the earlier described actions necessary t o make a left t u r n i n the

CLEANING A N D INSPECTION
Clean a l l p a r t s i n m i n e r a l s p i r i t s or other suitable
solvent, discard the body to reservoir " 0 " r i n g . T h e
p u m p shaft should t u r n freely and should be smooth
at the seal contact area. The flow c o n t r o l valve
bore and the valve should be smooth, free o f scores
or scratches. T h e valve m u s t operate freely i n the
bore.
N O T E : Small scratches can be removed w i t h crocus
