68 3000 gas with SLOW Dual 195 loader

Sorry of I posted in the wrong area, I have a Dual 195 loader, worked fine before I removed it to do some field work. Put back on and its slow , and has a bit of a groaning sound as it lifts. Its seems to be a self contained unit with the joy stick and tank attached to the frame. I just have to insert the pump shaft into the front of the engine area and bolt it on . Any ideas would be greatly appreciated. Bad with tools, some days I'm lucky. Most not tho

Sounds like dismounting and mounting it might have dislodged some gunk inside that is now blocking a passage. I would try replacing the fluid and filter(s) if it has any. If that doesn't help then you might need to disconnect the various lines and blow air backwards through the lines and through the control valve while exercising the joystick to dislodge whatever it is. Also check the intake side of the pump to make sure it isn't clogged.

I had one more thought. Check first to make sure none of the lines got kinked.

Thanks much for the quick response . As soon as I can I'll be in tearing stuff apart !! Trying to download or find a manual as well. I'm much better at breaking things than fixing but I'm learning , thanks to all you folks !!

Common for the "suction line" at the pump.... to collapse and restrict flow, and create a groaning sound. It will only collapse when the control is activated, drawing fluid, or sometimes collapse all the time..

also... Make sure level of fluid is not too low in reservoir.

Make sure any block valves on the remotes did not shut when you took loader off.

Rookie here ,how do I check that ?

I am assuming the loader comes out of the remotes, there should be a metal lever near each one, inline with hose is on, right angle is off.

Mickinohio - Ignore what David said about remotes as yours is not setup that way if the loader has its own pump that mounts on the front of the tractors.

I dumped the old fluid , looks greyish/black . refilled and noticed the long hose that goes from the control lever to the front pump seems to jerk as I lift the bucket. Going to try and get to Lashleys Tractor sales by me and talk to the service guy, they are a Woods dealer. I'll get a picture of the pump as well , maybe that will help.

That line should be the pressure line from the pump to the control valve. If it jerks when you try to lift the bucket, then the restriction is after that line in the circuit. Raise the loader and let go of the controls so the control valve spools are centered, then start to lower it and see if the same line jerks. Also, does it lower fast or is that also slow?

And how about the curling of the bucket, is that fast or slow compared to how it used to work? And does the pressure line jerk when you start to curl or dump the bucket without moving the lift arms?

That line with the hose clamps looks like it is the return line going from the control valve to the box below the control valve, which looks like the reservoir, and that line is also tee'd to another line (probably the suction line going to the pump intake). The pressure line should be the hard metal line going from the pump up to the control valve.

Where is the "relief valve" that you say spewed oil? Looking at that picture showing the top of the reservoir all shiny looks like it was the reservoir breather (fitting on top of reservoir just below control valve) was what spewed the oil. With that small of a reservoir you should probably only fill it when all of the cylinders are retracted (arms lowered and bucket curled).

Since that is an isolated system and is only being used for the loader you should be able to use any hydraulic fluid, but the manual for the loader will tell you what specific type the manufacturer recommends.

You should not have to worry about getting air into the system, as the reservoir is above the pump, so gravity should prime the pump, and simply cycling the cylinders from fully retracted to fully extended and back a few times should work any air out of the system. After you complete any work and refill the reservoir with the cylinders retracted, work them back and forth several times, retract the cylinders and check the fluid level again. If there was any air in the system that got worked out then the fluid level in the reservoir probably went down.

Since it lowers quickly the problem with it lifting slowly and making noises while doing so seems to be a restriction in the flow of the lift branch of the circuit. With the look of some of those hoses, it's possible that one or more of them might be breaking down on the inside and a piece of rubber has come loose and that is what's clogging things up.

As soon as the tax money comes back I was considering replacing them as well as a tune up anyway. About a week from now I hope to have it all done.

Thanks Sean and everyone for helping out . I'll update as soon as I'm done.
