Re: 990 selectamatic hyd. problem

The ball is too big if it is stuck in the bore. The bleed screw has to have a groove across the end of the screw, so that the oil can get around the ball and out trough the drilling in the bleeder. You need to have pressure from the valve chest when you bleed the cylinder. A low pressure from the li...

Re: 990 selectamatic hyd. problem

Are you sure that all parts have been fitted correctly (especially those in the valve chest) and have you done all adjustments to the Selectamatic system? There are 3 groups of settings to be done if you have stripped down the valve chest. All the adjustments have to be perform absolutely correctly ...

Re: AL2 front loader remote control cables

Try to take the damaged cables with you and go to a local company that sells hydraulic spool valves valves and remote cables for the valves.

Re: 1212 rear hydraulics/quadrant issues

You wrote " I’ve also cleaned out the 2 valves under the kidney shaped cover, 1 was clear the other a bit blocked". By saying that I assumed that you knew how to clean the valves, but obviously not. These two valves are the hold valve and the by-pass valve. These are the two valves you get to trough...

Re: 1212 rear hydraulics/quadrant issues

The one and only filter in the hydraulic system is the suction filter under the transmission. ALL oil going to the pump is first going trough the filter and that same pump is feeding both the loader and the 3-point hitch. Did you clean the small nylon screen and the small hole in the restrictor plat...

Re: 996 maintenance

The cooling system volume and all other volumes in your tractor are mentioned in the Operators Manual. A OPS manual also givers information about all levers and knobs and the use of these. In addition all service tasks are explained in detail, telling how much and what sort of lubrication and fluids...

Re: Question on the hydrashift

The JD you are referring to was a tractor manufactured and sold in the US. Completely unsuitable for farms in Europe in those days. I am talking about European needs and tractor models. I have also later on tested and evaluated the Case 1270 and 1370 tractors. Big tractors, no 4-wheel drive availabl...

Re: Question on the hydrashift

Hydra Shift was never built for loader work, David Brown have other models for this type of work. A Hydra Shift tractor is ideal for heavy pulling in the field or on the road. The range gears are mechanical and you can drive or start in any range (1, 2, 3 or reverse) but you have to stop the tractor...

Re: 1212 rear hydraulics/quadrant issues

It looks like it says " for Quiet Cab" on the manual you have. This manual is meant for a 1212 tractor with a cab with a floor in. All pictures you have sent, shows a non cab tractor. Most of the levers and controls are therefor different in your tractor, compered with what is shown in the manual. F...

Re: 1212 rear hydraulics/quadrant issues

Have you moved the 3-way valve lever to the correct position, as instructed. Please show a picture of the lever position as it is now.

Re: 1212 rear hydraulics/quadrant issues

The picture of the 3-way valve shows that the lever (it is not a switch) is fully at one of the end positions (looks to be fully left). The instruction given was to move the lever fully to the right and then back one "click" to the left from the fully right position. There is 4 positions for the 3-w...

Re: 1212 rear hydraulics/quadrant issues

To the original poster. A hoe is an implement, not an "back actor". The hoe is not connected to the pto, but to the lower and top links and this is called 3-point hitch. The pto is the shaft on the rear of the tractor pto housing. This is used to give power to rotating implements connected with a pt...

Re: 1412 Adjustable track rods

Widening the front track will NOT make the tractor more stable. The front axle can tilt the same amount regardless of the track. You need to widen the rear track if you need more stability.

Re: Engine Oil Filters.

Cobbadog, I would urge you to stop searching for the filters locally, they are not available on the open market, and this has been told to you and others, several times. There is absolutely no reason for why you can not buy these filters from UK. A lot of people from America and Canada are buying pa...
