1610-1004-RT-310 Hydrostatic Transaxle

1610-1004 / RT-310 Integrated Hydrostatic Transaxle

This RT-310 integrated hydrostatic transaxle is for repairs where the complete identity matters—not merely the appearance of the housing. It combines the hydraulic drive functions into one assembly and is intended to restore controlled ground drive when the original unit has been correctly identified as 1610-1004 / RT-310.

Why This Matters

Transaxles in the same general family can differ in axle, control, rotation, porting, and internal configuration. Ordering by machine brand or visual similarity alone can result in a unit that will not install or operate correctly.

Identification

Documentation

Use the equipment manufacturer’s parts catalog and service literature for the exact machine model and serial range. No universal installation document is being represented for this configuration.

Before You Order

Hydrostatic components are configuration-specific. Match the complete model/build code and inspect the photos and connections before ordering. A partial family match is not enough. Cross-reference numbers are identification/search aids unless expressly confirmed as direct replacements.
