Clutch coupling MPM Kasia 194 (old type) — MPM model Czę001282 cross joint replacement part

Clutch coupling MPM Kasia 194 (old type) is a replacement mechanical coupling designed to restore torque transmission between the drive shaft and sewing-machine mechanism in older Kasia 194 appliances. The part includes the cross joint (universal joint) that connects two misaligned shafts and compensates angular movement while transferring rotary motion. It is shaped and dimensioned to fit the older Kasia 194 coupling assembly and to reduce play that can cause vibration or loss of power in the drive train.

Advantages

This replacement coupling provides direct mechanical compatibility with the old-type Kasia 194 assembly and restores stable power transfer without requiring modifications to the machine. The integrated cross joint reduces axial and angular backlash, improving transmission smoothness and reducing wear on connected shafts and bearings. The part is compact and designed for maintenance use, enabling quick swap-out of worn couplings to return the appliance to reliable operation.

Suitable for

• Repair and maintenance of older MPM Kasia 194 sewing machines
• Replacement of worn or damaged cross joint couplings in the Kasia 194 drive assembly
• Workshop servicing where restoring torque transfer and reducing play is required

Key specifications

• Type: mechanical clutch coupling with cross (universal) joint
• Function: transmits rotary torque between misaligned shafts
• Fit: designed for old-type Kasia 194 coupling assemblies
• Construction: compact, service-replacement design to minimize play
• Material: metal components suitable for drive-train applications

How to use

Turn off and disconnect the sewing machine from power before servicing. Access the drive assembly according to the machine service instructions, remove the worn coupling, and inspect the surrounding shafts and bearings for wear. Position the replacement coupling so the cross joint aligns with the mating shafts, secure any retaining fasteners or clamps to manufacturer torque recommendations, and rotate the assembly by hand to verify smooth motion and correct alignment before reconnecting power. After installation, run the machine at low speed to check for vibration or noise, and tighten fasteners if necessary.

Usage recommendations

Use when the original coupling shows excessive play, noise, or loss of torque transfer. Inspect adjacent components during replacement and consider replacing worn bearings or seals to prevent premature wear of the new coupling.
