another 123 question (hydro newbie )

cjrolke · #1 07-30-2013, 02:34 PM

well I got the motor switched in to the 123 that I am working on

got it to run but not so much on moving

It was a little low on fluid so I added some hytran I had sitting

it moved a little bit forward and that is it

the drive shaft is spinning the pump is turning

one thing I noticed is on the pressure relief valves

one side will move up when the engine is running the other side is stuck down

I am currently soaking the valves with pb blaster to help free them up

if i could get some movement both in forwards and reverse i would feel a lot better about this one

should i keep soaking the valves and see if it will free up or split the tractor and then take the valves out ?

also i know i should put a new filter, drain the fluid and clean it out. could that be some of the reason she doesn't want to move?

i have 8 of these darn things and this is the first time i have had to work on a hydro

thanks

I think your problem is in the relief valves. They should be in the "up" position. Keep soaking them and they should free up. Check over the linkages good and it probably wouldn't hurt to change out the hytran and filter. Relief valves still get my vote. Good luck and keep us posted.

thanks

that is what i am leaning towards

this tractor was a parts tractor that i decided to rebuild

i hate to see them turned in to that

for some strange reason i wanted a 123

( i might even make a tiger cub out of her some day

)

I believe Josh is exactly right. If the valves are not all the way up she won't move (one valve for each direction).

I also agree that new fluid and a new filter wouldn't hurt anything.

Good luck!

STOP MESSING WITH THE RELIEF VALVES ON THE HYDRO - UNTIL YOU MAKE SURE THAT YOU HAVE JACK STANDS UNDERNEATH THAT CUB!!

I foolishly had a valve stick, soaked it in PB Blaster the same as you and tried to work it free while the cub was running and it had a mind of its own once that relief valve opened, knocking me down and running into the garage door only stopping because another cub got into its way!! I did something dumb and since then I learned the hard way. So, I am going to try to prevent anyone else from playing the fool, like I did! Safety first!! You are close to getting your problem solved by soaking the relief valves and changing the filter. The problem will be solved soon enough and everyone else who has commented has given you some excellent advice, and I concur with their words--I just wanted to iterate about safety first!!

BTW: Those are some excellent tri-ribs on the front of that 123, with some good looking rims!! I have the same on my 123 and love the way they handle/steer. Keep us posted on your progress.

thanks

I will put it up to start really messing with it

I have tri -ribs on almost all of my tractors

they steer so much better with that (and a nice cleaned up column )

nice looking 123!

how long can these hydro units sit before they are junk?
i have a 127 that's been outside and hasnt run since about 1991

I bought a 147 a couple of years ago that the PO told me had been setting outside in the pasture for over 14 years. Once I got the linkages freed from being rusted and put a new brake pedal and shaft in it, it runs and drives fine. Also had to replace steering column and clean spindles and bores in front axle. It does smoke a little though.

I'm gonna say that as long as they don't fill up with water, they should be good forever

Truthfully, I have seen pictures of hydro transmissions that have been taken apart because they broke down, so I know it does happen.

But for the life of me I CAN NOT imagine what anyone could do to a sun strand hydro transmission to tear it up (other than tow it).

I have more than 10 hydros myself, and I have abused the &#@* out of a couple of them... and they just keep on going. My Brother can't even tear one up, and he could bend a crow bar in a sand pile!

The last comment was a good one, Mark!
