Pneumatic Shift Cases:
Remove pin (T54 - prior to 9/25/98) or
shoulder bolt (T237) and self-locking nut (T238 - after 9/25/98) from
sector gear (T47) and actuating shift lever (T173). The removal of the pin
(T54) or shoulder bolt (T237) will release the tension on the shift arm
spring (T61). Remove shift shaft spring (T61). Remove sector gear (T47)
and actuating shift lever (T237).
14. Remove shift shaft (T46) and shift arm (T62) from mid-section. Remove
spring (T61).
15. Reposition mid and cap section assembly on the supports so that the cap
portion is on top as shown in Figure 2 or set the assembly on a bench.
Figure 2. Transmission Stand - Midsection & Cap
16. Remove four screws (T97) that fasten oil pump (T34) to pump support
housing (T31) and remove the oil pump. Do not remove the two (2) small
screws that fasten the pump together.
17. Press shift shaft bushings (T50) from mid-section. O-ring (T49) will come
out when bushings are removed.
18. Removal of cap from mid-section only required if either component needs
to be replaced.
Note that removal will make it easier to handle the
assembly during driven shaft removal and reassembly
. Remove cap
screws, bolts and nuts that attach the cap (T65) to mid-section.
19. Remove cap (T65) and its driven shaft assembly from mid-section or
spacer(s) (T100). Rapping the cap with a dead blow hammer will break the
adhesion between the cap and mid-section or spacer(s) (T100).
NOTE: Do not drive dowel pins (T103) into mid-section or spacer(s).
20. Remove any shims (T99) or spacer(s) (T100) between cap and mid-sec‐
tion. Protect shims from damage; they will be reused during reassembly
unless they are replaced.
NOTE: The quantity and thickness of shims and spacers depends on
case model and ratio.
NOTE: Before 8/05/96, models YB and YC, the dowels between the
cap and mid-section pass freely through the shims and spacers. On
models YD, YE, YF, the spacers are doweled to each other and also
to the cap and mid-section.
After 8/05/96, single cast spacers are used for the YD, YE and YF
drops.
