Re: Dead Clutch Pedal

Clutch Pedal Spring - Implematic and Selectamatic are available from David Brown Parts Ltd in the UK - Part Number 624909 at 14 GBP if that helps. Also there is a video on You Tube regarding the replacement of a clutch on a 3 cylinder DB Title is in German but video is in English. Its not for a 990 ...

Re: Dead Clutch Pedal

The spring should measure about 4" coil to coil in it's "at rest" position. Who ever managed to stretch the spring in your video past it's point of no return has had to use considerable force. You could not do it by hand. Andy

Re: Dead Clutch Pedal

The hooked part of the clutch lever should be hard up against the roller and is kept there by the spring, when you depress the clutch pedal the lever rolls round the pin and when you re-engage the clutch the spring brings it back. Previous comment about the free play adjustment bolt localed at the b...

Re: Dead Clutch Pedal

I agree with Gard - The clutch lever (with the hook on) should locate above the roller - (The pin with the holes in it) and the spring looks to be stretched so nothing will work as it is. If its something more serious inside is anyones guess. Attached is a photo of my 950 showing how the cluch assem...

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...

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...
