Worm Gear W0.3-3-5.5 for 1.5 mm Shafts (Replacement for Fleischmann 567608)

The brass worm gear W0.3-3-5.5 is designed for fine-pitch drives with 1.5 mm shafts in model railway applications. It transfers the motor torque reliably to the mating gear and can be used as a replacement for the Fleischmann worm 567608.

Dimensions:

• Module: 0.3
• Bore (inner diameter): 1.5 mm (tolerance +0.05 mm, −0 mm)
• Outer diameter: 3.0 mm
• Length: 5.5 mm

The precision-machined bore allows a play-free fit on shafts with 1.5 mm diameter. The small outer diameter of 3.0 mm makes it suitable for gearboxes with limited space.

Properties and benefits of the worm gear:

• fine 0.3 module tooth profile for smooth, even running
• compact dimensions for tight installation spaces
• suitable for repairs and conversions of model railway locomotives and vehicles
• can be used as a replacement part for Fleischmann 567608 (depending on the model)

Together with a suitable mating gear, the worm gear ensures precise, low-vibration power transmission between the motor and the drivetrain.

Handling notes:

• Always push the worm gear straight onto the shaft without excessive force to avoid damaging the bore.
• Deburr the shaft ends slightly if necessary so the worm can be pushed on cleanly.
• Align the worm carefully to achieve the lowest possible runout.
• Secure the connection to the shaft with a fast-curing metal adhesive to reliably prevent twisting or slipping.
