Kirby Geared Primary Drive Belt 554189S for G3 G4 G5 G6 Ultimate G Diamond Edition | Transmission Belt

Kirby Geared Primary Drive Belt – Part #554189S

This genuine Kirby geared belt is the primary drive belt used inside the transmission system of many Kirby upright vacuums. It transfers power from the motor to the transmission, allowing the self-propel (Tech Drive) system to operate.

Important:
This belt does NOT drive the brush roll. It is strictly for the transmission and self-propel system.

What This Belt Does:

• Transfers power from motor to transmission
• Enables self-propel (Tech Drive) function
• Controls forward and reverse drive operation

Common Signs of a Worn or Broken Belt:

• Vacuum no longer pulls itself forward or backward
• Loss of self-propel function
• Vacuum feels heavy and harder to push
• Grinding or slipping inside the transmission

Compatibility:

• Kirby Generation 3 (G3) – Transmission
• Kirby G4 – Transmission
• Kirby G5 – Transmission
• Kirby Generation 6 (G6 / GSIX) – Transmission
• Kirby Ultimate G – Transmission
• Kirby Diamond Edition – Transmission

Product Features:

• Genuine Kirby OEM geared belt
• Part number: 554189S
• Designed specifically for transmission (primary drive)
• Durable construction for long service life

Additional Fitment Note:
Kirby Sentria models use a different transmission belt (Part #554105S) and are not compatible with this belt.

Installation Note:
Installation requires opening the transmission assembly. Recommended for experienced users or professional service technicians.

If your Kirby has lost its self-propel drive or feels harder to push, replacing this primary drive belt can restore proper operation.
