  • Page 31 3) Place the spring into the drum. Fit the center edge of the spring into the slit of the bush by hammering. Put a steel plate or the like to protect the spring when hammering. 4) Place the outer edge of the spring on the spring fixing portion of the drum. See figure 37 (page 25).
  • Page 32 (5) Before reassembly, clean and inspect all the disassembled parts. Replace worn, cracked, damaged or deformed parts. (6) Lightly lubricate the bush attaching portion of the spindle and the inside surface of the bush with grease (IDEMITHU, DAPHNE EPONEX GREASE EP-1 or equivalents). Attach the bush with the circular hole to the spindle.
  • Page 33 (9) Stand the drum with the spindle being horizontal. Secure the drum by some means not to allow falling or moving. (10) Place the notch key and notch springs into the slot of the spindle. Take care as the assembling direction of the notch key depends on the winding direction of the reel.

  • Page 35: Common Reassembly Method

    4) Place the outer edge of the spring on the spring fixing portion of the drum. See figure 37 (page 25). 5) Insert a screw driver into the space between the band and the spring as shown in figure 38 (page 25), then remove the band. Take care not to catch your finger in the spring since the spring will expand explosively when the band is removed.

  • Page 36: Spring Disposal1

    13-4. Spring disposal The spring is dangerous due to remaining tension even if it is broken. Weld steel plates to the spring even if the spring is in the spring case in order to prevent the spring from expansion before disposal. Never use gas welding, only use arc welding.
