after separating the left side drom the right side by removing the jack shaft between them I was able to tell which side is locking up after 3 inches of movement. The left side (side with the 3 groove pulley). the right side turns free. I know where I might be able to get another hydro wheel motor but do I need to take the whole gear assembly out? gear box and all or will the hydro motor pull away from it? if I have to take it all out I can't image how heavy that will be. Not sure I can get to bottom of potential parts machine to unbolt it either. Thanks
mitey mac (2500)- do hydro wheel motors separate from gear box?

I can't remember if you mentioned it in any of the previous build threads, but do you have any manuals for this? Found a parts manual here that shows how things go together.
Often that helps to visualize something that's not easily observed when other things are in the way.

I do have parts manual but the schematics looks bit indepth to really tell. hoping someone may have taken the pump away from the big gear case and will know hands on what to do. I think I might take everything out.. but be nice to separate if can. Not sure if my issue (pulley only turns back and forth few inches) is in the hydro motor.. which I think it is.. or in the big gear box.
by the way.. Thank you!

It looks to me that there are only 4 cap screws holding each hydraulic motor assembly to the reduction box, the shafts are splined so they should just slide apart. It would be easier to get things out in sections, especially if it's a bit of a reach and you don't have mechanical advantage.
I'm betting that the problem is in the big gear reduction; it seems to me that there would be less free play in the pulley if the hydraulic motor was bad.
Thanks.. I will try to get back at it next week. My vette project is winning out as far as 'time involved on fixing'- to much to do and no time to do it. P.S. I bet your right on gear box.. even a big pipe wrench would only move it few inches. I didn't bear down on it but put a bit of pressure.
