Get your 'well trusted mechanic' to test the compressions on each cylinder.

Re: 780 power take off does not stop turning

A bit more detail on adjusting the PTO adjustment. Adjusting the PTO setting on a Borg and Beck two stage clutch is never easy whatever make of tractor. You would be lucky if you needed to do the adjustment on the David Brown 880 because it has two inspection holes. The majority only have one inspec...

Re: 885 q cab seized throttle

The foot throttle will more than likely be seized where it goes through the cab. Did you remove the metal panel under the dash? Removing this panel should enable you squirt penetrating fluid down on the inside if you cannot do it from the outside because of the loader. It is just a matter of letting...

Re: 880 Engine Stop Cable

Did you check the new cable was the same length as the old one, some of these new cables are shorter so the curve at the pump is more acute. Also make sure the cable run is smooth with no tight bends, oiling my help.

Re: 1290 Hydraulic problems

As philedge says the reason the main hydraulics are not working is that bolt so it needs to be removed.

Re: 1210/990 parts

The part numbers are different so there is a good chance the parts are also different.

Dont block the oil feed line under the camels hump if you still want to use the quadrant lever to control the 3 point link and anything connected to the 3 way valve.
I did mention that in my last post.

Re: 1394 control valve assembly - where is it?

You won't do because it's inside the axle casing. The dump valve screws into the control valve and sit on top of the hold valve. If you remove the dump valve and the plate it goes through you will see the bypass valve cap beside the hold valve,

Re: hydraulic david brown

If you remove the block and block the rearmost pipe, a suitable bolt with an 'O' ring on will do, this will block the oil supply to the control valve so none of the tractors hydraulics will work. Then you have a constant pressure feed to the loader controls BUT YOU MUST HAVE A RETURNS LINE IN FROM T...

Re: hydraulic david brown

Under the block there are three pipe ends, the rearmost one goes done to the control valve, the middle one comes up from the hydraulic pump and the front one is connected to the tractors internal lubrication system. If you look under the block you will see the rear two are connected whilst the front...

Re: 1594 Trailer Brake

It maybe the spool valve (it acts like an ABS) it sticks so the spool does not allow hydraulic oil to pressurise the trailer brake system. The spool can be accessed by removing the end cap, with the bleed screw on, and remove the spool and clean it up. Don't forget the brake will need bleeding after...

Just remove the outer cable clamp and the split pin from the end of the inner wire.

Re: clutch and brake fluid in highway

I am sure Highway tractors use the normal brake fluid used in cars and the like Castrol Girling for example not the oil used in agricultural DB's.
