Massey 65 front loader problems

the massey 65 I bought at auction has major hydraulic issues , I chained down the 3 point hitch and tried to operate the position control lever but the 3 pt doesn't respond at all ( doesn't raise or lower ) but it will raise or lower if I operate left stick on loader valve...right stick on loader valve only makes tractor shudder a bit ....In the pic I uploaded the hydraulic line coming out of the left side of top cover goes to raise side of left main cylinder , the one on the right side goes to raise side of right main cylinder...the main cylinders lowering side hoses are just hanging tied up at the cylinders not connected ??...on the control box the left top line goes to lower side of bucket cylinders, one on right lower goes to raise side of bucket cylinders...is this thing hooked up right?
 
I'll be glad to see your pics when monitor decides your ok as I am rebuilding a 65 and going to install a loader. I'm really stupid when it comes to hydraulics and spools valves and cut-off valves and the like. I do have a loader on a 35 with front pump so learning how to use the pto hydraulics is of interest.
 
its mounted on the cover, I tried to cut and paste the pic but that doesn't work...Ill have to wait for my wife to get home, she can probably figure out how to get a pic on here...the loader is model 46 john deere, looks as old as dirt and still painted green
 
I think you are not properly connected at the control box. One lever operates the loader and the other lever operates the bucket. Each lever has an in port (top) and out port (bottom).
It does not matter if the loader is connected to the left or right lever, either should work. Same for the bucket. Pumping hose and return hose for loader needs to be on same lever. Same for bucket.
Position control lever beside the seat needs to be in fully down position to activate the constant pumping action which provides fluid to loader.
Don't know why loader lever operates 3 pt. Check that your fluid switch between loader and 3 pt. is in correct position.
 
There are at least 3 different styles of those valves. The left lever controls the 3ph. That spool is strictly single action, which explains why the return hoses from the lift cylinders aren't hooked up. That side of the cylinders do need to be vented so air can enter and exit. The right lever is for a remote cylinder(s). It can be either single or dual action depending on which valve you have. Yours must be dual action to operate the dump cylinder. So, with the 3ph chained down, put the lever beside the seat in the up position and pull back on the left lever in front of the seat. That should lift the loader. Gravity will lower it when you push the lever forward.

Did you buy this tractor and loader already set up like this? If so, did it work for the previous owner or did they get frustrated and give up? I don't see how it could work set up like that.
 
I don't understand this hydraulic hose connection set up at all, I can see chaining down the 3 pt to redirect the flow into the loader hydraulics but this hose connection setup on the valve is confusing..one hose coming from the top cover goes to raise one lift arm the other hose coming out of the other side of the lift cover goes to raise the other arm...the down pressure hoses are just hanging unattached from the lift arms (where do these things hook up too?)...one hose coming out of the valve goes to raise both bucket arms, the other hose goes to lower them.. I did manage to get one bucket arm moving forward but then it stopped and wont mover anymore...I think Im going to scrap this valve and start from scratch
 
If it was on JD and you are using the same valve it may be a closed center valve that is your problem. JD was one of the few tractors that used closed center systems.
 
I bought it off an ebay auction for 1700 bucks, the loader did go up and down, but bucket didn't work...when I brought it home I removed chains from 3 pt( said to myself, what the hell are chains wrapped around this thing for, now I know why)...I put the chains back on but get nothing out of the loader arms, not even a hint of movement
 
Thanks for the pics. I am not an expert but it appears that you are only half hooked up. You can see two ports just behind the red ball levers, only one is being used. The loader should be on one and the bucket on the other.

Further back you can see one hose connected and an unused port; again the loader should be on one with the bucket on the other.

Make sure the pressure hose and return hose for the loader are operated by one lever. Same for bucket.
 
There are several ways to set up remote hydraulics on a 65. First you need to understand that the 3ph valve in located in the pump housing and there is no way to tap into the pressure between the pump and valve. That makes any remote setup on these tractors somewhat less than ideal. My recommendation is to replace the valve on top of the tranny with an after market selector valve, also called an isolator valve, and mount a 2 spool valve on the loader. Run a hose from the pressure port of the selector valve to in port of the 2 spool valve and another hose from the out port of the 2 spool valve back to the tractor. Hook up the loader hoses to the work ports of the spool valve. This will work but it will be slow. The pump in the tractor only puts out 4.2 gpm.
 
First, your position control lever beside seat needs to be all the way down for constant fluid pumping.

The red ball levers direct the hydraulic fluid. Push forward and fluid goes one way; pull back, the fluid goes the other way. One way lifts the loader or bucket, and the other way pushes them down.

In neutral, fluid goes to bypass and back to pump. I see two pipes in your pic, one on each side. I think the pipe on the brake side is your bypass. Where does it go? Where does the other one come from? Both have shut off valves. Turning one or both off should redirect the fluid to the 3ph.
 
The pipe on the right side with the shut off valve goes to the lift side of the right loader hydraulic cylinder, the one on the left side goes to the lift side of the left one...stramge aint it?...I'd like to meet the arse who installed this crap and kick his arse down the street for a while
 
Hi Dave, these things can be confusing and certainly had the previous owner stumped.

You have four ports on the spool valve, two behind each red lever. Connect the loader to the front and back ports behind one lever, and connect the bucket to the front and back ports behind the other lever.

The bypass and fluid return hose (the one on brake side I think) needs to feed back to the internal hydraulic fluid reservoir. Normally the return hose is connected into the inspection plate below seat (brake side) where you find the dipstick.

I am guessing that the hose with the shut off valve on the clutch side is for use with other equipment such as a trailer with a lift arm.
 
Thanks for the help with the hose redirections : ). Im going to have to pull this valve off and see what this clown did underneath ...I need to order all new hoses anyway, Im surprised they didn't blow out already (their in really bad shape)...Im still fixing all of the cobbed up wiring under the dash, it looks like he tried to wire the ammeter up like a voltmeter with solid copper phone wire
 
Hi Dave, If you are taking the whole spool assembly off you should be aware that there is a standpipe feeding from the pump which is low down. There are o rings etc. on the pipe that you will likely want to replace to prevent internal leakage that will drop your hydraulic pressure.

Good luck. Seems like the previous owner was really experimenting.
