Re: 885 Engine Rear Crank Seal

The one or two piece refers to the paper gasket ( not the seal) betwen the seal retainer and the cylinder block, but this info must be wrong. There has always been two halfs of paper gaskets (one for the top and one for the lower half of the retainer) as you can not fit a one piece gasket. It is not...

Re: 885 Engine Rear Crank Seal

I do not think you can slide he clutch to the rear with the tractor not splitted. The clutch release plate will but onto the release bearing. The best and fastest way is to split the tractor as for a clutch repair and then remove the clutch and the flywheel. Follow the procedure on pages 25 and 26 i...

Re: Red 880 Selectamatics

I have a list of serial numbers that suggests that the first 880 Selectamatic was built in October 1965 and had the serial number 530001. The list does not show if the tractor was red or white.

Re: David Brown 996 hydraulic issue

Feeding the 3-way valve from the trailer tip pipe (outlet 2, bottom outlet), will not let the oil to the lift cylinder (outlet L). If you want to feed the lift cylinder from a external supply, you will have to connect the feed to outlet 1 (top outlet on 3-way valve) and select 1/L with the 3-way val...

Re: David Brown 996 hydraulic issue

Please try!!. Erkki is talking about valves in the valve chest and you have by-passed the valve chest and you have also said that you have blocked the oil feed betwen the valve chest and the 3-way valve! There is no relief or any other valves in the lift cylinder. We can not go on like this and I th...

Re: DB995 brake master cylinder removal.

All David Brown tractors are made in UK. As J.I.Case was the owner of the company, they had the right to specify their own recommendations and build instructions for the US market.

Have a look in the following link https://drive.google.com/drive/folders/0B9-7bn5CX9NDNUpzY3pSaXQxWkU I think figure A3 in image 243 shows the studs (not rods) you are talking about 5/16 UNC x 1 7/8 inch All bolts and nut on a David Brown tractor are UNC (coarse thread) or in a few cases BSF (fine t...

Re: David Brown 996 hydraulic issue

Keeping the hydraulic main control lever fully back will also prevent the oil from leaking back. I think you have pushed the hydraulic lever forward and as this puts the valve chest into lowering you ended up with no lift. Keeping the control lever constantly in full lift position is not a reliable ...

I think you have been given all informations you need, or what do you think I was talking about when I wrote "If you remove the 3-way valve, you will find a pipe sticking out from the rear axle" and "This is the pipe betwen the Selectamatic valve and the 3-way valve, that has to be blocked off.

Re: David Brown 996 hydraulic issue

If you remove the 3-way valve, you will find a pipe sticking out from the rear axle. This is the pipe betwen the Selectamatic valve and the 3-way valve, that has to be blocked off. Have you measured the pressures I asked you to do?

Re: David Brown 996 hydraulic issue

There is no pipe from the 3-way valve to the lift cylinder, it is just a hole in the valve and the front of the lift cylinder. It is a 3-way valve with 4 positions at the operating lever, not a 4-way valve. Are you sure you have the 3-way valve lever in position L for operating the 3-point lift? Is ...

Re: David Brown 996 hydraulic issue

It looks like the feed to the extra spool valve is taken from the top plug on the camels hump. This is incorrect and the oil will escape trough the extra valve center drilling when you try to operaste the 3-point hitch The same will happen when you activate one of the two extra levers, the oil flow ...

Re: DB995 brake master cylinder removal.

There is no need for wondering about the fluid to be used. ALL David Brown brake and clutch hydraulics are built for mineral oil use and the oil with the needed spesifications is LHM. Using anything else can lead to problems. Dot brake fluid is ruinig the seals and a mineral oil with a lower viscosi...
