Re: DB 990A Implematic Hydraulics Not Working

Thanks for the updates on BSW and BSF! For my control arm, the part at the bottom that the "grub screw" goes into completely snapped off when I was trying to get the stuck bolt out. So I've attached a long nut (not sure what the term is, but that's how I view it 8=) with JB Weld. I'm using a threade...

Re: DB 990A Implematic Hydraulics Not Working

Thanks for the correction ollek. I'm just learning about the different thread standards and I knew it was British and Fine. And the other standard is Whitworth or something like that. Are they very common still in the UK? Or are the metric standards more common? Here in Canada the universal are stil...

Re: DB 990A Implematic Hydraulics Not Working

Thank you for the tips on the pushrods. I'm having trouble with the actual control arm as the bottom piece which holds the adjusting screw for the pushrod under it has snapped off. The previous owner put the wrong bolt in there (UNC rather than the BFT or BWT that likely requires). I applied a littl...

Re: DB 990A Implematic Hydraulics Not Working

It looks like there is something called a "mills pin" that is missing. I'm also missing a belleville washer to keep things properly tensioned for the friction washers. So I'll be picking those up as soon as I can. But the machine is working and I'm happy! I did put some SeaFoam conditioner in the fl...

Re: DB 990A Implematic Hydraulics Not Working

It took a while, but the fluid change is done. Next time I won't wait until the snow is flying to do it! There was a fair amount of water in the system but having a propane heater running on the back end for a couple hours got most of it and a diesel flush took care of the rest. The hydraulics are o...

Re: 3 way valve for 990 implematic

Thanks db2d and ollek for the answer to my question. I suspected it might be a project for the future, but now I know it isn't going to be worth it for this tractor. I can't think of any other need for the auxiliary connection in what I intend to use the tractor for.

3 way valve for 990 implematic

I'm learning so much about the hydraulics of my 990 the hard way. Lots of fun but dang awful timing! Anyway, a side question has popped up for me. Is it possible (and not too difficult to switch it to the 3 way diverter taps so that I could add an external hydraulic line if I needed to? Some snow bl...

Re: DB 990A Implematic Hydraulics Not Working

Thanks for the tips! Good to know that I don't have to remove that screw. I'd heard about the diesel thing before but I wasn't sure if it was the right thing to do. It kind of makes sense though. I suppose I can just put some in without building a gasket since it will only be in there temporarily. I...

Re: DB 990A Implematic Hydraulics Not Working

Yesterday I was able to warm up the tractor in a carport/tent with the temps just above freezing. I was able to get the drain plug and plate off to let all the fluid out. It was quite messy and sludgy after all. I guess the good stuff rises to the top for the dipstick to look at 8=) I'm having troub...

Re: DB 990A Implematic Hydraulics Not Working

Thanks for the tips! I may wait until Sunday since we are supposed to get a day of above freezing temps which might make it easier. I did look at the shifters and the rubber gaiter (I would have called it a boot) for the hi/low shifter was not in its proper place. It looks like it's intact so I put ...

Re: DB 990A Implematic Hydraulics Not Working

I didn't have a chance to get to the tractor today so I'll be working on it tomorrow. I did some reading though, and while I can see how to drain the oil and remove the mesh, I'm not seeing anywhere that describes how to refill it. It doesn't go back in through the dipstick opening does it?

Re: DB 990A Implematic Hydraulics Not Working

I was unable to get the cable to move - it is seized pretty good. I did look in the opening for the PTO cover and it seems that the rod is moving up and down. It is the one directly under the port, correct? I eventually decided to take the load off the lift arms and disconnect them from the ram shaf...

Re: DB 990A Implematic Hydraulics Not Working

Thanks db2d

My top link is not the original, so I'm not sure if I can hook up the cable (which the previous owner never used so it's likely seized 8-(

I'll definitely check the plug on top of the PTO unit and see what is in there tomorrow.

Thanks
Bill

Re: DB 990A Implematic Hydraulics Not Working

The diverter is where most of the documents show the 3 taps on the left side by the seat. It is a single tap. You actually helped me with this a week ago and I need to find a castellated nut to fit on it, but I manually move the valve in or out and it doesn't work either way (loader or 3 pt hitch)

Re: DB 990A Implematic Hydraulics Not Working

Thanks db2d!

Is it possible that there is a blockage in the ram cylinder that is blocked somehow? I can't see any other cause for both up and down not to work although I can't rule out multiple problems simultaneously.

Thanks
Bill
