TM 5-4210-220-34 3-7. TRANSMISSION - Continued (1) Using spring compressor J24219, depress the main pressure regulator valve spring.  Remove the snap ring (1). NOTE The spring compressor may be used whether the front support assembly is attached to or removed from the torque converter housing. (2)     Remove the spring compressor, and remove washer (2), valve stop (3), spring (4), and main pressure valve (5). (3)     Using the spring compressor, remove snap ring (6),  washer  (7),  valve  stop  (8),  spring  (9),  and  lockup  shift valve (10). (4)     The  spring  compressor  is  not  required  for  the  remaining  valve  components.    Push  inward  against  valve support  assembly  (11),  and  remove  snap  ring  (12).    Remove  support  assembly  (11),  seat  (13)  converter bypass valve (14), and spring (15). (5)     Remove the nineteen bolts (16) remaining in the front support assembly.  Lift off the front support assembly (17) and gasket (18). (6)     If replacement is necessary, remove the needle bearing (19) from the bore of the support hub. Special tool J28557 may be used to remove the needle bearing. NOTE Do not attempt this rework procedure unless adequate machining capabilities are available. (7)     Determine  the  serviceability  of  the  seal  ring  grooves  on  the  front  support  hub.    Insert,  without  force,  gage J29198-3 into a groove on the support hub.  Rotate the gage 360 deg.  around the hub. (8)     If the gage does not rotate freely, the support is damaged and should be replaced or reworked. NOTE A  damaged  or  worn  front  support  hub  can  be  salvaged  with  guidance  from  the  instructions  on  the instruction  sheet  in  the  sleeve  and  pin  kit.    The  kit  contains  one  unfinished  front  support  sleeve,  one sleeve retainer pin and one machining and installation instruction sheet.  Kit P/N 23011446 (21). If there is evidence of movement or damage to the ground sleeve, replace the front support and sleeve as an assembly. (9)     If the needle bearing (19) was removed from the front support, install a new bearing.  Installer J24197 may be used with handle J8092 for driving the bearing, or without the handle when press-installing the bearing.  Drive or press on the numbered side of the bearing until installer bottoms on housing for proper bearing depth. 3-35
