Product Description

SHIMANO 105N0 CAST CONTROL SPACER (TGT0182)

Fine-Tune Your Spool Tension

The Shimano 105N0 Cast Control Spacer (Part No. TGT0182) is a small but essential component located inside the mechanical brake (cast control) knob of Shimano's saltwater conventional reels. This spacer sits behind the friction washers, providing the necessary stack height to ensure the cast control cap can apply precise pressure to the end of the spool shaft.

If this spacer is missing—which frequently happens when the cap is removed for cleaning or lubrication—the cast control knob may bottom out before it actually touches the spool shaft. This results in a "loose" spool that cannot be tightened, leading to massive backlashes. Replacing this spacer restores the functional range of your mechanical brake.

Installation Tip: The Cast Control assembly is a "stack." Typically, the order inside the metal cap is:

1. Cast Control Spacer (TGT0182) (Goes in first, at the bottom of the cap).

2. Cast Control Friction Washer A/B (The felt or carbon washers that touch the shaft). If you put the washers in without this spacer, the spool shaft won't reach them.
