123 hydro HELP!!!

[cjrolke]

ok i am at my wits end on this one

I bought a 123 that was a parts tractor

I have a 10 hp that I just got in to it

tried to get it to move and got nothing
the relief valves were stuck so I split the tractor removed the valves and soaked them and have them freed up.

when I pulled them the white ring and o-ring were messed up (torn and distorted)
I replaced the o rings on both valves.

just got the tractor back together started the tractor and it went in to reverse for a few seconds and then nothing more. nothing in forward either.

It has fluid in it (probably needs changed) but it should be enough to move the tractor right?

if the filter is clogged would the pump bypass and still move? (the filter is from 2006 so its at least not the original filter, and it is a cub filter)

I hate to keep throwing money and parts at something like this if there is a major problem.

I know nothing as far as the history of the tractor so I am at a loss as to what to do next

I am half way thinking about cutting my losses and picking up another trans and go from there.

if anyone has any ideas I am listening

I am used to my gear drive tractors, working on a hydro is different for me


thanks

Change the filter .My local case ih has fleet farm ones for $10.

that is what I have been leaning to but don't want to throw good money after bad if it isn't the problem

There is NO bypass.

[cjrolke]

i thought there was something in the filter?

[J-Mech]

Not all filters have an internal bypass. The filter on this machine is on the suction side, and even if it did have an internal by-pass, I'm not sure the charge pump could "suck" hard enough to open it.

The filter is probably the culprit.

Is there a way to "bench test" the unit when split from tractor with electric drill motor wright up?.... My next question would be: {Not knowing about the history;} How can you tell if the tractor was pulled with the hydro release lever not released?

Maybe these questions answered can help decide if you should go get a known issue-free trans axel and pump unit. I have a 123 trans and don't know if it is any good.

Never know what the fluid is like inside until open up the rear cover. You can always save the transmission fluid if you determine it's good. Make a cardboard gasket. Hope you have the problem corrected at some point!
