NOTE: The planetary wheel drive assembly can be serviced with the planetary installed to machine. If the spindle (item 1) needs to be removed from machine, see Planetary Wheel Drive Assembly Removal in this section. 1 24 2 3 4 19 7 20 8 11 21 12 Disassembly (Figs. 8 and 9) 14 1. If planetary wheel drive assembly is installed on machine: 15 17 A. Park machine on a level surface, lower cutting decks, stop engine and remove key from the ignition switch. B. Drain oil from planetary wheel drive/brake assembly. 16 13 C. Chock rear wheels and jack up front of machine (see Jacking Instructions in Chapter 1 -- Safety). Support machine with jack stands. D. Remove front wheel assembly. 2. Remove retaining ring (item 12). 3. Remove end cap (item 14). Thrust plug (item 15) and thrust washer (item 16) usually remain in end cap bore and should be removed for cleaning and inspection. 4. Remove drive shaft assembly (items 17). 5. Remove carrier assembly (item 18). 6. If wheel stud (item 5) removal is necessary, use press to extract stud(s) from housing. NOTE: Steps 6 through 10 are necessary only if inspecting or replacing bearings and/or seals. IMPORTANT: Do not reuse retaining ring (item 10) after it has been removed. 7. Remove retaining ring (item 10) and thrust washer (item 9). Discard retaining ring. 8. Remove housing (item 6) from spindle (item 1). Remove outer bearing cone (item 8). 9. Remove and discard all seals and O--rings (items 2, 21 and 24). 10.If bearings will be replaced, remove inner bearing cone (item 3) from housing. Remove bearing cups (items 4 and 7) from housing. 11.If necessary, remove socket head screws (item 19) with lock washers (item 20) that secure ring gear (item 11) to housing. Remove ring gear and two (2) dowel pins (item 23) from housing. 9 Assembly (Figs. 8 and 9) 10 6 5 23 21 Figure 9 1. Thoroughly clean parts in solvent and dry completely after cleaning. Inspect parts for damage or excessive wear and replace as necessary. NOTE: Use new seal and shim kits when assembling planetary wheel drive. 2. If spindle and housing were separated: A. Press bearing cups (items 4 and 7) into housing. Cups should be pressed fully to shoulder of the housing bore. B. Set inner bearing cone (item 3) into bearing cup (item 4) that is installed in housing. C. Make sure that seal bore in housing is thoroughly cleaned. If OD of seal (item 24) is not rubber or does not have a sealant coating, apply light coating of silicone sealant to seal bore in housing. Install seal into housing so it is flush with housing face. Lightly grease seal lips. D. Pack boot seal (item 2) with grease and install on housing. E. If ring gear was removed from housing, place dowel pins (item 23) in housing. Secure ring gear to housing with lock washers (item 20) and socket head screws (item 19). Torque socket head screws to 9ftlb (12 N -m). 18 22 Axles, Planetaries and Brakes Groundsmaster 4100--D Page 6 - 11 Axles, Planetaries and Brakes
