92—Checking Clearance Between Front Pump
Body and Gears
limits are from .001" to .0025". After checking
pump gear clearance, lubricate pump rotors
with Automatic Transmission Fluid (Type A).
Measure the tip clearance between the rotor
lobes.
The manufacturing limits are .005" to
.008".
Replace the rotors if this clearance ex-
ceeds .010".
Measure the diametral clearance between the
outer rotor and pump housing bore. The manu-
facturing limits are .008" maximum. Replace
the rotors or pump housing if the clearance
exceeds .010".

REGULATOR VALVE BODY
AND VALVES
Place body and valves in pan containing a clean
solvent, wash thoroughly, and dry with com-
pressed air. Inspect the reaction shaft seal ring
surface in bore for scratches, nicks, or burrs.
Inspect both valves for free movement in valve
body; they should fall in and but of bores when
both the valves and body are dry. Crocus cloth
may be used to polish valves providing care is
exercised not to round the sharp edge portion
of the valves. The sharp edge portion is vitally
important to this type of valve, it helps to pre-
vent dirt and foreign matter from getting be-
tween the valve body, thus reducing the possi-
bilities of sticking.
Check all fluid passages for obstructions and
inspect all mating surfaces for burrs and dis-
tortion. If regulator valve body should have a
slight nick or raised portion on mating surfaces,
it may be removed by using a surface plate
and crocus cloth. Inspect front and rear pump
check valve for proper seating on both surfaces.
If necessary to remove valve, use a pair of long
nose pliers. When installing check valve, make
definitely sure rear pump check valve (with
metering hole) is positioned toward outside of
regulator valve body.
Check regulator valve spring seat (snap
ring).
After the valves and regulator valve
body have been thoroughly cleaned and in-
spected, the valves should be reinstalled in
body, (Fig. 69). Place assembly on a clean
surface and cover until ready for installation.
Inspect regulator valve and torque converter
control valve springs for distortion. Check regu-
lator valve spring sleeve and cup for burrs.
Check adjusting screw and locknut in retainer,
for freeness and pulled threads.

TORQUE CONVERTER REACTION
SHAFT—INSTALLATION
Using heat lamps, heat front of transmission
case to approximately 170 to 190 degrees F.
Install guide studs, Tool C-3283 in front face
of reaction shaft flange. Lubricate portion of
reaction shaft that presses into case with Auto-
matic Transmission Fluid (Type A). Position
torque converter reaction shaft into front of
transmission case so that guide studs in shaft
align with threaded holes in case.
Using Tool C-3531*, press reaction shaft in-
to place, as shown in Figure 70. Remove the
guide studs and start the three transmission
case to reaction shaft bolts and washers draw
down evenly, and tighten to specifications. Coat
torque converter reaction shaft seal (neoprene)
with Automatic Transmission Fluid (Type A)
and install on shaft.
