Re: 880 serial number please help

I think you will find that is the engine number. On the 880 the tractor serial number is on top of the chassis just in front of the radiator on the right hand side. Probably quite difficult to read if its had a repaint you may need strip some pain to find it. Search this forum in the right top of th...

Re: DB 990A Implematic Hydraulics Not Working

Just to add one small point to the comment db2d made regarding the main control lever connecting to a small push rod giving lift hold and drop - It does, and is located directly under the control lever acting on a cam inside the back axle - This as he said controls the up/down of the 3 point lift. T...

Re: DB 990A Implematic Hydraulics Not Working

Not a job I would fancy outside in the snow - It's bad enough in a workshop :) There is another drain plug about 6" behind the Screen Cover in the back axle. You don't say the age of the tractor but the earlier Implematics have a rectangular filter later ones are circular as per the link supplied. B...

Re: 990 Implematic

From what I have been able to suss both 2 way and 3 way valve were able to be installed as a retro fit by DB Stockists and BD produced this pamphlet to assist in their installation. Both use the same connection point but to fit the 3 way you replace/don't install the 2 way, with 2 unions Oil Supply ...

Re: 990 Implematic

There is a document DBT 218 called Fitting instructions for the David Brown Isolating Valve - It deals with the U90D (2 way valve) and it's removal and replacement with U279 (3 way valve) for All Series Tractors With External Hydraulic Equipment dated 1965 which covers the Implematic - In it there i...

Re: 4600 selectomatic

Click on board index

There is a couple of posts there as how to do it

If your using Apple you can click and resize the image but it takes a while and a few goes to get it right

Keep resizing and trying to send - Eventually you will hit on a size that works :idea:

Re: david brown 900 diesel

What exactly are you looking for here? Someone to repair your nose cone? - Someone to donate some 900 grills? Attach some pictures of the nose cone - so we know what we are dealing with. I don't mind having a go at it but you will have to deliver to Pembrokeshire and leave it with me for a while, Am...

Re: david brown 900

No - It's not necessary.

If it was me I would use some copper slip or the like on the taper to help get them apart in the future.

If you have the old type replace the split pins in the castleated nut or if they are the newer type replace the nylock nut with a new one.

Re: Information on a 1490?

Ask the previous owner for the V5 Document - If it has not got one it may never have been road registered. The V5 should be transferred with the tractor (it's a legal requirement) but for some reason they don't seem to be. I have a 950 that was sold with a V5 but on closer inspection the serial numb...

Re: david brown 900 diesel

DSC_0027 4jpg.jpg Attached is a photo of new nose cone for an implematic that is available - Note the poor fit of the grills, the hole to accept the DB Badge that the 900 does not have and the narrow strip between the grills that on the 900 is wider. If you go down the new nose cone route and want ...

Re: david brown 900 diesel

The 900 bonnet only fits a 900 - the nose cone opening and grills are different on the other "younger" red/yellow tractors. An early 950 "pre implematic" Bonnet with the rectangular side hinged radiator opening would be the nearest swap as they are the same length but the nose cone takes the tapered...

While you had it to bits did you replace the inlet valve rubber seals?

950 Front Axle

While refurbing my 950 front axle I thought to take off the hubs and replace the oil seals as they were looking a bit past it I smelled a rat when the split pins that hold on the castleated nuts were 2" wood nails but pulling the hubs off someone had used the inner races as drifts to "press" the out...

Re: david brown 900

Where is the breather pipe for the rocker cover vent piped into? On the early tractors they were piped into the inlet manifold and if they came blocked would pump oil straight into the engine They were later modified to discharge into the chassis Try taking the "wire wool" out of the breather and se...

Re: 950 Bonnet and Throttle handle?

You could try Pocock Tractor Supplies on the net or Flea Bay John Conaughty in Ireland were selling whole new bonnets a while back but I think they have run out now unless they have had a new stock in. Good second hand straight bonnets are like hens teeth, most have a flattened top to a greater or l...
