5. As in the Fig. 6, take the ball bearing 627, and disassemble into (Clunk shaft complete) ,(Washer 6,7,10),and
(rod-pin6, blade holder).
6. Pick out Pin6 by rbor, etc.. The Pin 6, connecting
the rod with the blade holder, is inserted with
pressure into the both side holes of the rod.
[Assembly Order and Note]
The assembly order is contrary to that of disassembly. Besides, the followings are the points which you should
be careful of during assembling.
1. When you put the needle bearing into the rod with pressure, press it until the bearing corresponds to the side of
rod. At that time apply greese to the needle bearing
2. When you put the ballbearing 627 into clunk shaft with pressure, be sure to check if the flat washer 7 and 10
have been put or not.
3. In attaching the parts of Fig.6 to Gear housing, be careful enough about gouging.
4. Fasten tightly the setscrew , fixing Yoke to Gear housing, so that it will be loose because of vibration during
operation.
5. When you coordinate Gear Housing with Gear Housing Cover, you must check the existence of Flat Washer 6
for sure.
6. Pay attention to Armature Ballbearing because it is sealed in one side only and the direction is fixed.
Ballbearing 608LB ----- Sealed in Fan side, Open in Gear side
Ballbearing 627LB------Sealed in Fan side, Open in rear end side
(Adjust Method of Shear Blade)
1. Attach the lower shear blade to the attaching surface of blade without gap, and fasten temporarily.
2. Put the upper shear blade on the fixing site of bllade in Blade
Holder.
3. Between Upper and Lower blades, insert Washer 5 as many
as possible. ( in case of Fig. 8, 3 pcs)
4. Insert the number of washers ( minus 1pc from the above; in
Fig.8, =2pcs) between Blade holder and Shear blade, and
fasten tightly the hexagonal-hole bolt for fixing Upper shear
blade. ( Ref. Blade clearance : 0.1- 0.2mm)
5. At the time of dead point on Upper shear blade, as Fig.-9,
put Upper/Lower blades so that they may overlap each other
by 2-3mm , and fasten strongly the hexagonal-hole bolt,
paying attention not to make a gap in the Positiion A.
6. Apply Screw Lock Super 103Q a little to the screw part of
Hexagonal-hole setscrew Fig.9, then put it into the lower tap
of Yoke, and make it attach in the condition that the end
of .Setscrew should hit the side of Shear blade. This time, do
not fasten the setscrew so tightly.
