(Fig.1)[3] Disassembling and AssemblingNote:As listed to left, the grinders use differentspiral bevel gears, and they are notinterchangeable.Referring to this list, therefore, be sure touse correct gears for replacement.Model No.GA7010CGA7011CGA9010CSmaller spiral bevel gear(on armature shaft)11 teeth9 teethLarger spiral bevel gear(on spindle)37 teeth43 teeth[3]-1. Replacing Armature, Smaller Spiral Bevel Gear and Ball Bearing 6201LLBDISASSEMBLINGFig. 2Note:Disassembling can be done without disassembling Gearhousing section.1) After removing Carbon brushes, by removing four 5x30 Tappingscrews, Gear housing section can be separated from Motor housing.2) Slide Gear housing cover until you see the corners on the end ofMotor housing. And then by striking two of the corners with plastichammer, the assembly of Armature and Gear housing cover can beseparated from Motor housing. (Fig.2)3) Remove Hex nut M6 by turning counterclockwise while holdingArmature firmly by hand. Now smaller Spiral bevel gear can beremoved from Armature shaft by hand.4) Remove Gear housing cover from Armature using Gear Extractor,large (No.1R045). (Fig.3)Ball bearing 6201LLB is still on Gearhousing cover at this step. Therefore, remove the bearing witharbor press and a round bar.

(Fig.5)2) Install smaller Spiral bevel gear on Armature shaft, and tighten Hex nut M6 securely with a spanner 10.And then install the assembly of Armature and Gear housing cover on motor housing, and align the screw holes on Gearhousing cover with those of Motor housing.3) Aligning the protrusion on gear housing with that on Motor housing, fit Gear housing to gear housing cover. (Fig.6)Fasten Gear housing to Gear housing cover and Motor housing with four 5x30 Tapping screws.Fig. 5Fig. 6Gear housingGear housing coverArmatureMotor housingGear housing coverBearing Setting Plate(No.1R035)Align the projection on Gear housingwith that on Motor housing.[2]- 2. Replacing Larger Spiral Bevel Gear and Ball Bearing 6202DDWDISASSEMBLINGNote:Disassembling can be done without disassembling Gear housing section.1) Using a Makita impact driver and Hex shank bit M5 (No. 1R229), remove four M5x16 Hex socket bolts that fastenBearing box to Gear housing.2) Insert two slotted screwdrivers into two diagonal positions on the slit between Bearing box and Gear housing.And twist the two screwdrivers at the same time till Bearing box is lifted up approximately 3mm.And then insert the screwdrivers further into the slit, and remove Gear housing from Gear housing cover by lifting itup with the screwdrivers.
