Re: 995 Hydraulic issues

Not sure about your tractor but the older ones like a heavier oil than Hytrans, I assume you have the owners manual? I have seen it recommended to move the tractor someplace where the front is higher, then the pump and lines are submerged in oil so pump will still work if a O-ring or pipe is damaged...

Re: Dead Clutch Pedal

The shaft that is below the one that the pedal mounts to should be rotating by way of a lever that connects the 2 shafts. This is the cross shaft that actually operates the clutch mechanism. It is hard for me to tell if something is missing or just installed incorrectly and why it would of been disa...

Re: Tyre Swap

Thanks, my experience is the auto paint is dry to the touch in a around 10 minutes and it took more like 24 hrs to get there with the tractor paint. I know this will depend on temperature, humidity and the exact type of paint. With the auto paint you could prime a part, clean the paint gun have a cu...

Battery cable size (AWG)

What would be the correct (or best) battery cable size for a 900 diesel tractor? The battery is mounted on the side so quite close to the starter. What is on there now is not original. Alternately if there is a guess about the current draw of the starter I could look up a size/length/voltage drop. T...

Re: Tyre Swap

I tend to go by the paint manufactures instructions, in general the automotive epoxy primers can go over any sound surface. I do not think a small amount of sound rust by itself is a problem. There is an acid pretreatment sometimes recomended but often the primers are self etching. I have used wire ...

Re: Tyre Swap

I like using automotive paints, the primer is a 2 part epoxy and the enamel top coat has a hardener added. The 2 pak or 2 part paint dries an a couple minutes, seems easier to get a good looking job and seems much tougher than the what is sold at the tractor supply store. On some parts I do the sand...

Re: Tyre Swap

In our area the tire company sends a service truck out with a guy that can take the old tires off and install the new ones and also deal with the fluid ballast if required. This was done with wheels attached to tractor and I thought it was a pretty quick and reasonable price. After watching him once...

Re: 1967 David brown 990 very slow to tip trailer.

I have used basically the same procedure SteveCollett describes on the 990 implematic tractor for many years when the front end loader is needed. For some reason the manual I got from the local dealer at the time (1991) did not cover the hydraulics well or at all. After the internet came along and I...

Re: piston rings and bearing shells

My local auto parts store has gauges for both oil pressure and water temperature (with sender). They have worked well for me. These were reasonably priced and came with a handful of adapters. If I was going to do it again I might look for something designed to be used in exposed areas, I think a lit...

Re: Wear in 880 Selectamatic Linkage

I have also used a large bolt and nut, it takes out a lot of the movement. The bolt goes thru the frame on the tractor, thru the ball on the lower link with a nut holding it all on. I am sure replacing all the parts would be better but in the meantime this does help. On the other tractor, a new pin ...

Re: Gearbox Oil

I also use the SAE 80W/90 GL-4 Mineral oil in the old tractor. I recently got a more modern tractor, the book recommends warm up of 30 minutes or more at -20C (-4F) if mineral oil is used. I read someplace that warm up was not required with the synthetic oil option (Kubota) so that is what I put in ...

Re: 1965 David Brown 880UE Implematic, adding thermostart

Do you know what the thread size is of your manifold and thermostart? I wonder if it would fit in my 990 implematic.
Diameter and threads per inch are fairly easy to measure if it is not installed yet.
Thanks

Re: 1965 David Brown 880UE Implematic, how to prime transmission hydraulic pump?

I agree you need the manual for your specific implematic system. I was able to get my implematic TCU system to work by building a simple bracket to hold the cable extended because I did not have a proper top link. The dimensions of the bracket was determined from the manual. My understanding is the ...

Re: 1965 David Brown 880UE Implematic, how to prime transmission hydraulic pump?

I think you are correct about which valve is which, If you have not done so already, I suggest disassemble and cleaning of each, there are some small passages in them if I remember correctly.

Re: 1965 David Brown 880UE Implematic, how to prime transmission hydraulic pump?

Its an interesting mystery to me as to what is not working in there. I know I would have a hard time giving up on the original system but I do not have any one tractor that I really need on the farm. I can understand the need to get it working one way or another (external pump) but its kind of a sha...
