cub cadet 149 issues
 

Hello,

I am new to site I need help with my Cub 149 hydrostat. While blowing snow this winter, the shaft from engine to charge pump came off flex coupling and cut open the trans filter, along with some other damage. I replaced the shaft, cooling fan, flex coupling, and drive flange. I filled the hydro w/ fluid. Now it acts like the tractor wants to move but doesn't. Any ideas?

First, welcome to OCC..........:Welcome2:

I would check the Spirol Pin that secures the Drive Flange to the input shaft of the Hydro.

:Welcome2:

As the 149 came with a solid coupling, it sounds like your 149 has been updated at some point to a flex coupling! :bigthink:

Anyway, I have seen some hydraulic systems that are hard to bleed after a filter change, especially if the wrong alternative filter is substituted.

So, my question is,

did the correct filter get installed?? :bigeyes:

Welcome to OCC! Good luck with your 149. They are great tractors. :beerchug:

149's do have a flex coupling at the back, anda solid drive pin like the rest of the n/f's at the front. Is this your setup?

From the Parts Manual......Check that item #36 that secures item #4 to the Hydro Input Shaft is not broken.

Yep,
The 149's came from the factory with the flex coupling or "rag" joints as some call them. Check your relief valves and make sure one of the tabs isn't stuck down.

Yup, this is where I'd start, then the spiral pin in the trans input shaft as Roland suggested.

Hi I replaced the drive flange, spiral roll pin, cooling fan,flex coupling and main shaft. when the old one came appart it damaged the filter as well, so i replaced that and filled rear differential with hy-trans fluid to top of plug hole. this 149 has a hydrulic lift and that works just fine. thanks chuck s
