Bosch 1609B00388 — genuine Bosch pulley for slide mitre saws. This metal pulley (Bosch part 1609B00388) restores the drive/belt geometry and smooth power transfer on affected saws; it’s one of the Bosch power tool parts designed for the GCM12SD and GCM 12 GDL.

Direct-fit replacement, shown as position 178 in the exploded view; manufactured in metal for long wear and straightforward installation (basic hand tools or a screwdriver are normally all that’s required).

Example compatible models: GCM12SD (type 3601F65010 / 3601F65011) and GCM 12 GDL series (various 3601M236xx type numbers) — confirm your machine’s type number against the diagram before installing.

Also listed under alternate number formats (1.609.B00.388 / 1609B00388); sold individually so you can replace just the worn pulley and get the saw back to original alignment.
