If it is difficult to remove the shifting cable, some models enable the outer casing holder to be

pulled out from the outer casing holder section of the cassette joint by turning the pulley of the

cassette joint.

Oil maintenance of the internal assembly

For internal 8-speed (oil maintenance kit: Y00298010)

In order to maintain proper performance, it is recommended that you lubricate the internal unit after riding

1,000 km from the start of use, then after about once every year (or once about every 2,000 km if the bicycle is

used very frequently). If the bicycle is used under harsh conditions, more frequent maintenance is required.

Also, for carrying out maintenance, the use of SHIMANO internal geared hub grease or a lubrication kit is

recommended. If SHIMANO grease or a SHIMANO lubrication kit is not used, problems such as a malfunction in

the shifting unit may occur.
