● When reassembly of the speed change and reduction sections is complete after disassembly, adjust pressure contact force
according to the following procedure.
● When reassembling the speed change section, move the ring to the low speed end (output shaft) in advance.
● Procedure
(1) Remove the top cover in the speed change section, look into the inside, and adjust pressure contact force according to the following procedure.
(2) Only for W type (with worm reducer), loosen the hexagon socket set screw. *Refer to the disassembly and reassembly diagram for the worm reducer section on page 19

After adjusting to 1º to 3º,
add a shim 0.2 mm thick.
Model Clearance of the cam disc
3700 to 18K
Adjust clearance to 0 to 0.1 mm, and add a
shim 0.1 mm to 0.15 mm thick (0.05 mm to 0.1
mm thick when applying pressure).
(3) Hold the cam retainer with pliers, etc., and check that the total
backlash is within the range of values in the table below.
If backlash is too large or small, remove the bearing cover (HS blind
cover for W type), and adjust to the normal value by increasing or
decreasing the shim (0.1 mm to 0.2 mm thick).
(4) Only for W type (with worm reducer), tighten the hexagon socket set screw after shim (pressure contact force) adjustment.
(5) Set the dial.
* Refer to the procedure for the standard NRX □ on page 12.
(3) Look into the inside of the speed drive, and check that clearance between
the cam disc and input cam is within the range of values in the table below.
If clearance is too large or small, remove the bearing cover (HS blind cover
for W type), and adjust to the normal value by increasing or decreasing the
shim (0.1 mm to 0.2 mm thick).
