Figure 5-76. 5-29. Cleaning Refer to paragraph 5-2 for cleaning recom- mendations. 5-30. Inspection and Repair Refer to paragraph 5-3 for general inspection and repair recommendations. Repair and overhaul (rebuild) points of measurement for fits, clearances, and wear limits are indicated by small letters in figure 5-74. Refer to paragraph 6-3 and table 6-3 for general wear limits information. Do not scuff, cut, tear, or distort Teflon seal ring. 5-31. Assembly (fig. 5-74) NOTE All items not covered in a and b below or in separate rebuild sections, are installed as outlined in paragraph 5-58, assembly steps 11 through 20 (fig. 5-93 through 5-102). No overhaul (rebuild) of such components is required or recommended. a. Intermdiate-range Clutch Piston Housing Assembly (fig. 5-74). (1) Install seal expander (fig. 5-77) into outer groove in piston. NOTE Both ends of seal expander must be as shown in figure 5-77 when it is coiled. Ends must curve away from seal ring so that they will not gouge seal. (2) Starting at a point opposite open ends of expander, install seal ring in groove. It will be necessary to stretch outer seals slightly to get them into the groove. NOTE Do not stretch seal any more than is absolutely necessary. (3) Install seal expander (fig. 5-78) into inner groove of piston. NOTE Both ends of seal expander must be as shown in figure 5-78 when it is coiled. Ends must curve away from seal ring so that they will not gouge seal. (4) Starting at a point opposite open ends of expander, install seal into groove. (5) Center piston in piston housing, and push evenly into piston bore. The broader, flat side of piston goes toward housing bore. (6) Install 12 springs (34) in housing assembly (25). b. Low-and Reverse-Range Clutch Piston Housing Asspembly (fig. 5-74). (1) If necessary to replace any of six anchor pins (54), press pin(s) into housing (52) until end of pin with hole projects 1.85 inches from flat side of housing. Hole in end of pin must point ap- proximately toward center of housing. (2) If necessary to replace two anchor pins (53), press them in until end of pin(s) projects 0.62 inch from flat side of housing. (3) Install reverse-range clutch piston hook- type seal ring (55) and low-range clutch piston hook-type seal ring (50). (4) Install seal expander (2, fig. 5-75) on reverse-range clutch piston (3, fig. 5-75) in same manner as instructed in a (1) above. (5) Install reverse-range clutch piston seal ring (1 , fig. 5-75) in same manner as instructed in a (2) above. (6) Install seal expander (48) on low-range clutch piston (47) in same manner as instructed in a (l) above. (7) Install low-range clutch piston seal ring (49) in same manner as instructed in a (2) above. (8) Center reverse-range clutch piston (3, fig. 5-75) and low-range clutch piston (47) in their respective bores in housing (52), and push each evenly into bores in housing. The broader, flat sides of pistons go toward housing bores. 5-34
