Features and benefits

Repair
(1) Tools necessary for repair
1. (+) driver
2. (-)driver narrow tip (width about 5mm)
3. Cir-clip pliers (for shaft)
4. Arbor press
5. Resin hammer(or wood hammer)
6. Bar or pipe (diameter:27, length:25 or more)
(this is for making works easier)
(2) Lubricating spots
Apply Makita grease R No.00 or Makita hammer oil XLD (0.5g-1g) for the following places to prevent wear in
early stages and seizure
1. O-ring of impact bolt
2. O-ring of striker
3. Crank joint

4. Piston joint
5. Tooth surface of gears
6. Needle bearings
7. Piston cylinder- inside and outside
8. Lip surface of oil seal 12 and oil seal 28
9. Both sides of Vespel washer 28
(3) Disassembly and Assembly
1. Chuck
As shown in the sketch, pull change ring to the last, then remove out cap 34 to the direction of the arrow.
After that, pull out change ring, key 4, and
conical compression spring 21-29.
2. Tool Holder
After removing set screw of gear housing(M5x55),
take off gear housing with a little shaking.
As shown in the sketch, press an arrow point
by arbor press to take off tool holder.
(If arbor press is not available, tap it
by resin hammer lightly.)
Note) At this time, ensure they are put to the depth
in order toprevent mislocation of oil seal and
ball bearing in the gearhousing.

3-1 Disassembly of impact bolt and idler As shown in the sketch, insert (-) driver (tip width 5mm
approx.)through the hole of tool holder and hook ring spring
by driver tip . Then, push it up to remove from the groove.
Also follow the same procedure in the other hole as there are
two hole.
After taking off ring springs, push impact bolt by the driver
tip. Then, it will come out with idler and flat washer 13.5.
3-2. Assembly of impact bolt and idler
Make sure of the direction of impact bolt, idler and flat washer 13.5 for assembly.
Assemble idler and flat washer facing R
and C to the unit inside.
Make sure of applying grease on O-ring of impact bolt.
Insert ring spring with finger to the depth and fit it in the groove using (-)driver as shown in the sketch.
(pipe or bar<Ø27-27.5>is recommended for pushing. It will make fitting to the groove easier.)
4-1 Disassembly of crank Remove three screws from crank housing.
Applying driver on pin 8, tap it lightly by hammer since pin 8
in the bearing of bell crank is pressed in lightly.
Be cautious not to lose washers used on both sides of bell crank
at disassembly working.
As shown in the sketch, washer has a special shape.

5. Gear housing packing
Always replace to a new gear housing packing in disassembly and assembly.
Be sure of removing grease in mating face of gear housing and gear housing cover.Then, apply Super Three
Bond No.50 evenly and thickly.
(Old packing may cause grease leakage as it has lost
elasticity.)
6. Replacing armature
Ensure to fit flat washer 14 in armature bearing of motor housing (see the sketch above).
Insert armature after assembly of ball bearing 6000 and oil seal (should be new) to gear housing cover.
(Wrong order of assembly and use of used oil seal may cause grease leakage or jump out of oil seal.)
7. Connection of rotation changing switch
Peel out cover of lead wire(6-7mm) and
finish in soldering. Push it until a part of
the lead wire coverenters terminal hole.
