Rotary groups, cylinder blocks, valve plates, piston assemblies, drive shafts and swash plates for the mainstream pump and motor families - rebuild a pump or motor instead of replacing the whole unit.














































| Part | What it does |
|---|---|
| Cylinder block | Houses the pistons; bores wear oval over time and lose flow |
| Valve plate | Times the oil in and out of the block; scored faces cause pressure loss |
| Piston & shoe | Converts swash-plate angle into pumping stroke |
| Drive shaft | Spline must match the coupling — check tooth count |
