Be sure that the slot on the spindle is indexed properly with its lock pin bore in the carrier (fig. 217). j. Using a press and spindle replacer 8351266, install the planetary carrier spindle (fig. 217). The spindle replacer will bottom against the carrier when the spindle is proper- ly positioned in the carrier. k. Install the lock pin, using a hammer and punch (fig. 213). Drive the lock pin flush to 0.030-inch below the carrier surface. l. Install the remaining five spindles 7 (fig. 377, fold-out 6) and pinions 14, with rol- lers 10 and 12, thrust washers 8 and 15, lock pins 16 and spacers 9, 11 and 13 in the same manner as described in b through k , above. — m. Install bearing 20 in reverse-range carrier support 18. Install retaining ring 21. n. Install reverse-range planetary car- rier assembly 6 in the carrier support 18. Press on the carrier assembly until it bottoms in the support. Section XXIV. LOW- AND REVERSE-RANGE PISTONS AND HOUSING — REBUILD 182. DESCRIPTION The low- and reverse-range clutch pistons are contained in a common, machined steel housing. The pistons, piston return springs, retainers, ring seals, seal ring expanders and retainer rings contained in this housing for low- and reverse-range are identical and inter- changeable. 183. DISASSEMBLY (fig. 376, fold-out 5) a. Position the low- and reverse-range clutch piston housing assembly in a press (fig. 218). b. Using a compressing tool (fig. 38), remove the retaining ring retaining the piston return spring retainer (fig. 218). Remove the retainer. c. Install eighteen piston return springs 49 (fig. 376, fold-out 5). d. Remove the low-range clutch piston (fig. 218). e. Remove ring seal 52 and expander 51 (fig. 376, fold-out 5) from low-range clutch piston 50. f. Remove ring seal 53 and expander 54 from piston housing 55. g. Remove reverse-range clutch piston 60, piston return springs 61, retainer 62, re- taining ring 63, ring seals 57 and 58, and ex- panders 56 and 59 in the same manner as de- scribed for low-range in b through f, above. — Figure 218.
