After removing the socket with a wrench, etc., lift off the plate, wave
washer and cover, and replace the coil assembly. After replacing the
coil, first tighten the socket by hand while holding down the plate and
wave washer, and then tighten it further with a torque of 0.8 to 1N⋅ m .
∗ Precautions when attaching and removing the socket
• Be careful that the O-ring installed on the bottom (plate side) of the socket does
not fall out or become chewed up, etc.
• Be sure to hold the body with a wrench, etc., and tighten the socket within the
tightening torque range given above. If excessive torque is applied, there is a
danger of damaging the threads.

In case of type 300, the cover
alone cannot be removed because
