Cross-reference note: These numbers are commonly routed to the same Ogura GT1A-HU02 clutch family, but aftermarket listings may show different pulley measurements depending on how the pulley is measured. Verify your original clutch number and physical specs before ordering.

Pulley Measurement Note

You may see different pulley measurements online for the GT1A-HU02 clutch path, including measurements around 5-5/16 inch, 5-15/16 inch, 6.00 inch, or 6.10 inch.

This can happen because V-groove PTO clutch pulleys may be measured at different points. A narrower belt can ride deeper in the groove, while a wider belt can ride higher. Some listings measure the effective belt contact area, while others measure the outer pulley flange.

Fitment rule: Match the original clutch part number first, then confirm bore size, belt width, connector style, anti-rotation setup, and pulley geometry before ordering.
