CHAP 5, SEC XXX LEFT, RIGHT OUTPUT Section XXX. LEFT- AND RIGHT-OUTPUT 212. DESCRIPTION Refer to pars. 26 and 27 for the descrip- tion of the output drive planetary assemblies. 213. DISASSEMBLY *C* a. Left-output Drive Planetary Carrier – Assembly (18, fig. 385, fold-out 14) (1) Remove three spindle lock pins 21 from output drive planetary carrier 20. Drive pins tmvard the center of the carrier. (2) Using a suitable pressing tool, re- move three spindles 19 from carrier 20. (3) R e move three planetary carrier pinions 24, with washers 22 and 27, spacers 23 and 26 and rollers 25. Place parts in sepa- rate containers and identify them with their location in carrier 20. Place the spindles in the same containers. b. Ri~ht-outmt Drive Planetarv Carrier Asse–mbly (41, f{g. 386, fold-out 15). The left- and right-output drive planetary assem- blies are identical, therefore the disassembly procedure is the same as described in a(1) ‘bough 2(3), above. 214. CLEANING Refer to par. 71 dations. for cleaning recommen- 215. INSPECTION AND REPAIR Refer to par. 72 for general inspection and repair recommendations. Repair and re- build points of measurements for fits, clear- ances and wear limits are indicated by small letters in figs. 385 and 386, fold-outs 14 and 15. Refer to par. 248 and 249 for wear limits information. 160 PLAN ETARIES REBUILD DRIVE PLANETARY 216. ASSEMBLY PAR 212-216 ASSEME LIES —- REBUILD a. Left-output Drive Planetary Carrier – Asserr@~.g. 385, fold-out 147 Note. Chill spindles 19 i n dry ice for o n e hour, if p[wsible, prior to assembly. (1) Coat the bore;; of pinions 24 with grease. Note. If any one of the pinions must b e replaced because of clef ects o r damage, it will be r,ecessary to re- place a 11 three pinions with a new matched assembly. (2) Install a pinion alining tool into a pinion 24. Note. A suitable al:.ning tool can be improvised by grind:ng an unservice- able spindle to O. 005 inch undersize and brazing a handk to one end. (3) Place a spacer 23 ancl thrust washer 22 on one side of pinio~ Y?4. (4) Install 20 needle rollers 25 into the pinion bore in the space a:?ound the alining toed. (5) Install ‘a seconc. spacer 26 and thrust washer 27. Remove the alining tool. (6) Install the Iinion, with the two spacers, two washers ar.d 20 rollers into the carrier. Aline its bore with the spindle bore in the carrier, using the alining tool. (7) Place the carl ier in a press, with the larger outside diameter side of the carrier up. Remove the alining tool. (8) Start a spindle 19 into the bore of the carrier. The spindlt: must be accurately alined so that its lock pin groove will be paral- lel with the lock pin hole in the carrier. _____ _
