TRANSMISSION REPAIR (Continued).
(h) Place needle bearing (173) into ground
sleeve (188) with the numbered end of the
bearing cage facing up. Using bearing
installer and driver handle, drive the
bearing into the ground sleeve. The
bearing, when installed, must withstand a
200 lb (91 kg) load without moving.
NOTE
If the tools are not available, drive the
bearing (numbered end of bearing cage
up) into the ground sleeve until the
bearing is 1.240-1.260 inch (31.50-32.00
mm) from the face of the hub.
(i) Place the oil pump body and gear
assembly (187) on the work table, front
side down. Align the bolt holes in front
support assembly (171) with those in
assembly (187). Install two 5/16-18x1-3/4
inch bolts (186) approximately 180 degrees
apart. Tighten the bolts one or two threads.
(j)
Install centering band around the oil pump
body and front support assembly (169).
Install the remaining ten 5/16-18x1-3/4
inch bolts (186) and two 3/8-16x1-1/2 inch
bolts (185).
(k) Check the centering band to ensure a
secure fit. The split line between the pump
and the support must be perfectly smooth
after bolt installation. Torque twelve 5/16-
18 bolts (186) to 17-20 ft-lb (23-27 N.m).
Torque the 3/8-16 bolts to 36-43 ft-lb (49-
58 N.m).
(I) Install main regulator valve (183) and
lockup valve (184) longer land first, into
their proper bores in support assembly
(171).
(m) Install springs (177 and 182) and valve
stops (180 and 181) into their proper bores.
Install main regulator and lock-up valve
spring compressor and adapters on front
support. Compress the springs and stops
to allow installation of pins (178 and 179).
NOTE
If valve pin installer is not available,
install the guide pin and components
to extend 1.16 to 1.20 inches (29.5 to
30.5 mm) above the finished surface.
(n) If valve guide pin (174) was removed,
replace it with a new one. Using valve
guide pin installer, plate the pin into the
installer. Place spring (175) and valve
(176) onto valve guide pin (174. Install the
valve guide pin and components into the
front support.
(o) Lubricate sealring (172) with an oil-soluble
grease (Appendix D, Item 21) and install it
into the groove on the outer circumference
of the oil pump body. Be sure the sealring
does not twist in its groove.
NOTE
Front support sealrings (170) must not
be installed onto the support hub until
final assembly of the transmission.
