Hydrostatic Transmission (HST) and Hydraulic Diagnostics
The hydrostatic transmission is the heart of your Morooka. Issues here can render the machine immobile. We use advanced pressure-testing equipment to isolate the problems with pumps, motors, or relief valves.
Watch for these common signs that your hydrostatic transmission repair needs immediate attention:
- Sluggish response: The machine struggles to climb slopes it previously handled easily.
- Drifting: The carrier pulls to the left or right when tracking straight.
- Overheating: Hydraulic fluid temperatures spike during normal operation.
- Cavitation noise: High-pitched whining noises often indicate cavitation, risking severe internal damage.
We also offer specialized service for hydraulic cylinders. We reseal and re-chrome dump bed cylinders and turning cylinders that face high-stress loads. Our in-house hose shop fabricates custom high-pressure lines that match Morooka OEM specifications perfectly.
For long-term health, we recommend our hydraulic system maintenance programs. This service includes scheduled oil sampling (S.O.S.) to detect internal metal wear before it causes a complete transmission failure.
