Confirm before ordering

Match the complete equipment model Sony TC-WR870 and the replacement reference SBS 2.9. Similar model numbers can use different mechanisms.

Quantity required: The earlier application reference calls for two SBS 2.9 belts, but exact correspondence to the TC-WR870 mode-belt positions remains unresolved. Sold per belt; confirm the original position and specification before ordering.

Additional belts used by this equipment: FBS8.0. Those belts are different sizes or profiles and are sold separately; SBS 2.9 alone is not a complete belt kit.

Equipment compatibility

Model and replacement reference

Brand: Sony
Model: TC-WR870
Replacement belt: SBS 2.9

Service documentation, the equipment model plate, and the original belt path take precedence where they differ.

Manufacturer belt positions: Sony’s TC-WR97ES/TC-WR870 service manual identifies separate mode belt 3-356-603-01 and capstan belt 3-356-604-01 for the TC-WR870 mechanism TCM-200R9 (printed page 32). The supplied SBS 2.9 belt has not been independently mapped here to either original component. Do not transfer an FR-belt reference from another TC-WR model.
