Separate the assembly of Gear housing complete with Armature from Motor housingcomplete by unscrewing four M5x35 Tapping screws.2) Separate Bearing box from Gear housing complete by unscrewing four M6x22 Hex socket head bolts.3) With Armature securely held by hand, remove Hex nut M8 from the drive-end of Armature shaft by turningcounterclockwise with wrench 13. (Fig.1)4) Hold Small spiral bevel gear by hand, then pull off Armature from Gear housing complete. (Fig.2)Note:If it is difficult to pull off Armature by hand, do the following steps.1. Lubricate small spiral bevel gear and Armature shaft with spray lubricant.2. Wrap the gear with cloth to protect the gear teeth.3. Using water pump pliers or the like, firmly grip the gear wrapped with cloth, then turn the gear.Fig. 1Fig. 2Hex nut M8Small spiral bevel gearGear housing complete,viewed from the wheelinstallation sideP4/9Repair[3] -1. Armature, Small spiral bevel gear, Ball bearing 6301DDW (cont.)DISASSEMBLING5) In order to remove Ball bearing 6301DDW from Gear housing complete, first remove Retaining ring R-42 withRetaining ring R pliers RT-2N (1R005), and remove Flat washer 20 from Gear housing complete. (Fig.3)6) Reassemble Armature to Gear housing complete, then the spiral bevel gear to Armature shaft. Tighten Hex nut M8provisionally by turning clockwise. (Refer toFig. 2, 1)7) By tapping the end of Gear housing complete with a plastic hammer, Ball bearing 6301DDW can be removed togetherwith Armature. (Fig.4)Note:Felt ring 18 falls off from Gear housing complete in this step. Be sure to mount to Gear housing completewhen assembling the machine.8) Remove Ball bearing 6200DDW from Armature with Bearing Extractor (1R269).
