That spin has to be geared down and redirected before it can turn the wheels at a useful speed. The turbine gear assembly is the set of gears that does it, and everything about how the cleaner moves depends on that gear train being intact.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe symptoms\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA worn or stripped assembly shows up as a cleaner that is clearly getting water and turning its turbine, but crawls, stalls, pulls to one side or refuses to climb the wall. Owners often chase the hoses or the booster pump first when the gears are the real cause.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOrdering\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis is the turbine gear assembly and comes complete.
