165 3 point

I got the 165 with 3 point 3-14 plow out today to plow my garden made one round put the plow back down started to go and spun out, back up a little and try to pick it up but it wouldn"t so i unhooked it and the arms fell to the ground and now they wont lift. any suggetions???

This can be many things. But, I am giong to start with a very stupid question... but sometimes things like this can happen. Are you sure you have not touched any lever by accident unnoticed and therefor have trouble ?
This was the stupid question.

Then to others things that might be the problem. As you describe it, you have lost the oil to the hydraulic cylinder. It can be a blown cylinder, it can be blown o-ring on the cylinder, on the transfer pipe, a blown transferpipe, or,... and here comes a little tricky one.
Inside the right side inspection cover, you will find the levers coming down to the control valve, and there are 2 of them, and the act on a small roller on the end of the arm for the control valve. Through this roller there goes a small bolt, and with a nut on the end. If this nut has managed to get off, and the bolt has gone out, the roller drops to the bottom of the centerhousing, and it should be obvious that it will do no good down there. The control valve will be pushed by the spring to a full drop position, and the liftarms will as you say, just drop down...

This is fairly easy to find out, just take off the inspection cover where the dipstick sits, and use a torch and have a look. And, you can also move the quadrant levers for position control and draft control, and see if they move the control valve.... that is if the little roller is still in place.

If everything looks ok, you can start the tractor with the inspection cover off, and try to move the arm for the control valve back and forth, and see what happens.

Then there is one more thing I came to think about, does the PTO shaft turn when you turn it on with the lever ? If not, you have a loose or broken connection sleeve between the transmission and the hydraulic pump.

If the PTO turns as normal, and the roller is there, and the valve moves as normal, you can try with a mirror inside, and a good light to look for an oil leak when you try to lift, and the engine run on a bit above idle. Look up on the cylinder to see if there comes any oil out, or the transfer pipe, it is located in front of the right side inspection cover, you can feel if with your hand, from the top down to the pump.

Hope you got some ideas...

Hi,
Errrr Bill, the 165 has one vertical lever.

David, you win for a while because this internet connection is too slow for me to back up what I meant with 2 levers. I can not open any online parts catalog to show what I meant. Until later in the evening or tomorrow.


Bill

Hi Bill,
Sounds like pistols at dawn!!!!!!!!!Lol

DavidP

Lol David, relax, no need to oil the pistols, no need to practise, just relax with a cup of tea... I am a friendly fellow. Some pranks though... but never want to harm anyone.

Have a nice sunday, until I can explain myself.


Bill

tore it in half today pulled out the pump and the pins that hold the pto brake in place broke and one of those pins got jamed and put the hydro in bypass get some parts monday and go from there

David, when I needed the manual, I can't find it. Typical.

So now I sit here like a fool.... lol

But, anyway, the tractor I remember from, it is perhaps 15 years ago, it had the same arrangement as a MF 35 or 65, with the exception of that the holder for the 2 levers, like the 35/65, went inside the arm for the control valve on the pump. You know, on a MF 35 and 65, you can lift the hydraulic cover up, without any problem once you have taken off the bolts around the cover, but on the one I think about you needed to take the roller of the arm to the control valve.

Is this the type without power control ? Or, have they made a change at some point ?

The type with power control, is as you say, with only one lever, and it is a totally different arrangement than the one I described.
