These 36V cordless combination hammers have been developed based on Models BHR261 and BHR261T, and feature compatibility with both Makita 36V-2.6Ah Li-ion battery BL3626 and 36V-2.2Ah Li-ion battery BL3622A. (Note: BHR261 and BHR261T run on only 36V-2.6Ah battery BL3626.)
Other features are exactly the same as BHR261 and BHR261T as follows:
• 3 operation modes (rotation only/ rotation with hammering/ hammering only)
• Vibration absorbing handle and soft grips
• Good tool-balance due to the center of gravity closer to handle HR262TD/BHR262T are equipped with quick change chuck.
These new products are available in the variations listed in the next page.

When removing Ball bearing 6001DDW, remove Retaining ring WR12 from Armature shaft in advance. Then remove Ball bearing 6001DDW together with Sleeve 12 using 1R269. Note: Retaining ring WR12 is firmly seated in the groove of Armature shaft, and the groove is so small that the ring cannot be removed with a pair of commercial retaining ring pliers only. Therefore, slip the gap of the ring outside of the groove using 1R004 or 1R291, then remove the ring using commercial retaining ring pliers or 1R003 with 1R212.

When inserting Armature into Inner housing complete, do not fail to pass Armature through Yoke unit in advance.
Note: Yoke unit is not directional when assembled with Armature.
Without enough care, Ball bearing 6001DDW on the drive-end of Armature may often be incompletely seated in the bearing room of Inner housing complete. Therefore, fit Ball bearing 6001DDW completely into the bearing room in Inner housing complete while carefully turning Armature by hand to engage the gear of Armature shaft with Spiral bevel gear 26 in Inner housing complete. Then fix Ball bearing 6001DDW with Bearing retainer and two M4x12 Hex socket head bolts.
Note: Be sure to apply adhesive (ThreeBond 1321B/ 1342 or Loctite 242) to the threads when reusing M4x12 Hex socket head bolts removed from the machine because they are threadlocking bolts.
Make sure that the five parts shown below are set in place before mounting Housing R to Housing L.

Put Gear housing complete on arbor press table, and keep it upright. Then, by pressing down Oil seal 25 using 1R252, Oil seal 25 and Needle bearing complete can be removed from Gear housing complete
with gentle pressure. Note:
On arbor press table, Gear housing complete can stand almost upright on its end edges. Although the end edges are rather thin, you need not worry about breakage because Oil seal 25 and Needle bearing complete are fitted to Gear housing complete with low press fit force.

DISASSEMBLING
Fig. 44
Note: This step can be done without removing Motor section.
1) Remove Gear housing complete as instructed in [3]-5.
2) Remove Inner support complete by loosening two M4x25 Hex socket head bolts using 1R170. (Fig. 44)
3) Remove two M4x12 Hex socket head bolts that is seated on Bearing retainer B on Inner support complete. (Fig. 45)
4) Remove Swash bearing 10 portion and Piston cylinder portion from Inner housing complete. (Fig. 46)
5) When Ball bearing 606ZZ is left in Gear housing complete after removing Swash bearing section, insert Cam shaft into the hole of Ball bearing 606ZZ and tilt Cam shaft back and forth (Fig. 47), then tap Gear housing complete with plastic hammer as drawn in Fig. 48. Ball bearing 606ZZ can now be removed.
6) Put Spiral bevel gear 26 on a U-groove of 1R139 as shown in Fig. 49, then press down Cam shaft using 1R281 to loosen the press fit of Cam shaft to Spiral bevel gear 26, Ball bearing 608ZZ and Ring 8 at a time. (Fig. 49) Also Clutch cam, Swash bearing 10, Sleeve 9 and Bearing retainer B can be removed from Cam shaft in this step. (Fig. 50)
7) By removing Retaining ring S-7 from Cam shaft using 1R291, Compression spring 7 and Spur gear 10 can be removed from Cam shaft. (Fig. 50)

Note: Be sure to apply Makita grease RB No.00 and Molybdenum disulfide lubricant to the specific portions shown in Figs. 1, 2 and 3.
1) Onto Cam shaft, slide Swash bearing 10, Sleeve 9, Spiral bevel gear 26 in order, then press-fit them using 1R032, 1R033 and arbor press.
2) Slide Bearing retainer B onto Cam shaft in advance, then press-fit Ball bearing 608ZZ then Ring 8 onto the shaft; be careful not to fix Bearing retainer B between the bearing and Spiral bevel gear26.
3) Onto Cam shaft, slide Super gear 10 and Compression spring 7 in order, then secure them with Retaining ring S-7 using 1R291.
4) Mount Guide plate then Piston joint to Piston cylinder. (Fig. 51)
5) Fit Compression spring 14 over the boss of Inner housing complete. (Figs. 3 and 52)
6) Insert the pole of Swash bearing 10 through the hole of Piston joint, then mount Swash bearing portion into Inner housing complete. Secure Swash bearing portion by fixing Bearing retainer B to Inner housing complete with two M4x12 Hex socket head bolts. (Fig. 53) Note: Be sure to apply adhesive to the threads of the two M4x12 Hex socket head bolts.
7) Insert Change plate into the groove of Clutch cam, then secure Inner support complete with two M4x25 Hex socket head bolts. (Fig. 54)
