When to Replace Your Timing Belt

• Belt is cracked, frayed, or shows visible wear
• Teeth are damaged, worn, or missing
• Belt has stretched and timing is off
• Machine skips stitches or forms irregular stitches
• Needle hits the hook or bobbin case
• Thread loops or tension issues that aren't resolved by adjustments
• Belt makes unusual noises during operation
• As preventive maintenance during major service

Why Timing Belts Are Critical

The timing belt is one of the most critical components in your Bernina sewing machine. Unlike motor belts that simply transfer power, the timing belt controls the precise synchronization between the needle, rotary hook, feed dogs, and other internal mechanisms. This precise timing is essential for proper stitch formation. If the timing belt is worn or damaged, the machine's timing can slip, causing skipped stitches, thread jams, or even mechanical damage if the needle strikes the hook.

Timing Belt vs. Motor Belts

It's important to understand the difference between timing belts and motor belts:

• Timing Belt (Part #0015265000): Controls internal timing and synchronization of machine mechanisms - this product
• Motor Belts (Upper/Lower): Transfer power from motor to machine - different parts

Your Bernina 1000 series has both timing belts AND motor belts. They serve different functions and are not interchangeable.

Installation and Timing

• IMPORTANT: Timing belt replacement requires re-timing the machine
• Proper timing marks must be aligned during installation
• Needle-to-hook timing must be verified after installation
• This is an advanced repair - consider professional service if unfamiliar with timing procedures
• Consult service manual for timing mark locations and procedures
• Test stitch formation thoroughly after installation

About Bernina 1000 Series Models

The Bernina 1000 series models are well-regarded sewing machines known for their reliable construction and excellent stitch quality. These machines use sophisticated timing systems to coordinate all internal mechanisms. Regular inspection and replacement of the timing belt is essential to maintain precise stitch formation and prevent mechanical damage.

Note

This is a quality replacement cog timing belt designed to meet original specifications. Timing belt replacement requires re-timing the machine and is an advanced repair. If you're not experienced with timing procedures, we recommend having this service performed by a qualified technician. Verify your model is listed before ordering.
