How to rebuild your Hydro-Gear transmission yourself! Had an issue with my Gravely Zero-Turn mower where a small part broke off inside the Hydro-Gear Hydrostatic ZT-3100 transmission pump on the left side and the machine would not drive as a result. Had to tear down the entire Hydro-Gear, clean it out, replace the broken part, and reinstall all the gaskets, snap rings, and seals with replacements. In this video I walk you through all the activities to do this job yourself with basic hand tools on a work bench. These transmissions cost about $1,000 to replace so attempting a repair is always a good idea. Repair is nearly identical for ZT-2800 and ZT-3400.
