Parts involved: Belts, pulleys & gears →
5. MBL S5M1225 Main Shaft Motor Belt 30mm for Tajima TFMX TMFX TMBP-SC TMAR TMCR Series medium likelihood
How to tell
Machine motor struggles to turn, inconsistent needle bar movement, unusual squealing or slipping noises from the main motor area, visible cracks, fraying, or missing teeth on the belt.
Fix
- Power off and unplug the machine.
- Locate the main shaft motor belt, typically connecting the main motor to the machine's main shaft.
- Inspect the belt for cracks, fraying, missing teeth, or signs of glazing/slipping.
- If worn, replace with a new MBL S5M1225 Main Shaft Motor Belt 30mm. Adjust tension as per the manufacturer's specifications in your machine manual.

6. Timing Pulleys (e.g., Tajima 32 Teeth Synchronous Belt Pulley, Tajima 501457010000 W25-60 Timing Pulley, Tajima W35-16 Timing Pulley Synchronous Wheel) low likelihood
How to tell
Excessive belt wear, belt slipping, grinding noises, play in the shaft, or visible wear/damage to the pulley teeth. Misaligned embroidery or timing issues may also occur.
Fix
- Power off and unplug the machine.
- Inspect the teeth of all accessible timing pulleys for wear, chips, or deformation.
- Check for any wobble or excessive play in the pulley on its shaft.
- If a pulley is damaged, replace it with the correct part (e.g., Tajima 32 Teeth Synchronous Belt Pulley, Tajima 501457010000 W25-60 Timing Pulley, Tajima W35-16 Timing Pulley Synchronous Wheel). Ensure proper alignment and secure fastening.
Inspect all pulleys associated with the timing belts, as wear on one can affect belt life and machine timing.

Maintenance schedule
| When | What to do | Why |
|---|---|---|
| Daily (or every 8 hours of operation) | Clean the rotary hook area and bobbin case. | Removes lint and thread debris that can cause stitch imperfections, thread breaks, and wear on the hook. |
| Daily (or every 8 hours of operation) | Oil the rotary hook and needle bar drive mechanism. | Ensures smooth operation of critical moving parts, reduces friction, and prevents premature wear. |
| Weekly (or every 40 hours of operation) | Clean the entire thread path (tension discs, thread guides, take-up lever). | Removes wax, lint, and thread residue that can affect thread tension and cause thread breaks. |
| Weekly (or every 40 hours of operation) | Inspect needles for damage and replace as needed. | Dull or bent needles cause skipped stitches, fabric damage, and thread breaks. |
| Monthly (or every 160 hours of operation) | Inspect timing belts (e.g., Tajima MBL S5M625 Timing Belt 25mm, MBL S5M1225 Main Shaft Motor Belt 30mm) for wear. | Early detection of cracks, fraying, or missing teeth can prevent unexpected belt failure and timing issues. |
| Monthly (or every 160 hours of operation) | Inspect cutter blades (Tajima High-Speed Plastic Cutter Assembly FD Motor) for sharpness and cleanliness. | Dull or dirty cutters lead to poor trims, frayed threads, and potential thread jams. |
| Every 500-1000 hours (or Annually) | Inspect all timing pulleys (e.g., Tajima 32 Teeth Synchronous Belt Pulley, Tajima 501457010000 W25-60 Timing Pulley) for tooth wear and play. | Worn pulleys can cause belt slippage, timing issues, and accelerate belt wear. |
| Every 500-1000 hours (or Annually) | Check and clean sensors and switches. | Ensures proper machine function and prevents misreads or malfunctions. |
| Every 500-1000 hours (or Annually) | Lubricate all specified points as per manufacturer's manual. | Comprehensive lubrication ensures all moving parts operate smoothly, reducing friction and extending machine life. |
Stop and call a technician if
- If you encounter persistent error codes that cannot be resolved with basic troubleshooting.
- For any issues involving the main motor, circuit boards, or complex electrical components.
- If you suspect a major mechanical failure, such as a bent shaft or damaged main bearing.
- For precise timing adjustments that you are not comfortable performing yourself.
- If you experience recurring problems after replacing wear parts, indicating a deeper issue.
Prevent it coming back
- Always use high-quality needles appropriate for your fabric and thread type.
- Ensure proper thread tension to reduce stress on needles, hooks, and thread path components.
- Keep your workspace clean and free of dust and lint, which can clog machine parts.
- Use only manufacturer-recommended lubricants and follow the specified lubrication schedule.
- Avoid running the machine with dull needles or damaged rotary hooks, as this can cause further damage.
- Operate the machine within its recommended speed limits to reduce wear and tear.
Frequently asked questions
How often should I lubricate my Tajima TMCR machine?
Lubrication frequency depends on usage. Generally, daily oiling of the rotary hook and needle bar area is recommended. Other points may require weekly or monthly lubrication. Always refer to your Tajima TMCR operator's manual for specific lubrication points and intervals, as well as the recommended type of oil.
What are the most common wear parts on a Tajima TMCR?
The most common wear parts on a Tajima TMCR series machine include needles, rotary hooks, bobbin cases, cutter blades (part of the Tajima High-Speed Plastic Cutter Assembly FD Motor), and timing belts (like the Tajima MBL S5M625 Timing Belt 25mm and MBL S5M1225 Main Shaft Motor Belt 30mm). Regular inspection and timely replacement of these parts are key to preventing downtime.
Can I perform all maintenance myself, or do I need a technician?
Many routine maintenance tasks like cleaning, oiling, and replacing needles or bobbin cases can be performed by an operator. However, more complex tasks such as timing adjustments, motor diagnostics, or replacement of major electrical components should typically be handled by a qualified embroidery machine technician. Always consult your manual and know your limits.
How do I know if my timing belt needs replacing?
Signs that your timing belt may need replacing include visible cracks, fraying, missing teeth, excessive slack, or unusual noises like squealing or flapping. Performance issues such as skipped stitches or misaligned embroidery can also indicate a worn timing belt. Regular visual inspection is the best way to catch wear early.
