The CAT 307B Final Drive is a complete hydraulic travel motor built to power the tracks of Caterpillar 307B midi excavators. If your 307B is losing tracking power, travelling unevenly, or leaking gearbox oil, a replacement CAT 307B final drive can restore full travel speed and responsive steering control.

The 307B is closely related to the earlier 307 and later 307C, and also comes in a 307B SB configuration. Its drive system is fully hydrostatic, and the final drive combines a hydraulic travel motor with a reduction gearbox to convert hydraulic flow into controlled track movement. Because specifications can differ across these related models, confirming your exact variant helps ensure the correct final drive is supplied.
Common signs you need a CAT 307B final drive replacement:
These symptoms can also stem from hydraulic, undercarriage or control-system faults. It’s worth checking the wider travel system before replacing the final drive itself.
Because the 307B shares its platform with the closely related 307 and 307C, and also has a distinct SB variant, final drive specifications should always be confirmed rather than assumed. Send us your model, serial number, plus photos of the existing unit with its hydraulic connections, so Arena Hydraulic and Machinery can confirm the correct fitment before you order.
